The increase in the number of EVs on the road has also increased the demand for more charging stations, which require high-end components to keep them running cool. Pump Technology Keeps EV Charging Stations Cool The increase in the number of EVs on the road has also increased the demand for more charging stations, which require high-end components to keep them running cool. KNF Cool Stuff Jul 9, 2025 Sports The world has become more environmentally conscious, and emissions regulations are becoming stricter, making electric vehicles (EVs) increasingly popular. As the demand for newer, better EVs increases, so too does the demand for the charging stations that are necessary for keeping EVs powered and operational. These stations will need to be installed both commercially and residentially as more drivers move to EVs. Also from EE: Hydraulic Gimbal Aids Iron Man’s Motion Control Because charging stations output so much electricity, they also generate substantial amounts of heat. There are three different levels of chargers, with levels one and two available for both public and private use and level three available for public use only. The level three DC Fast Chargers (DCFCs) can output up to 500 A and 350 kW. Even more powerful chargers are on the horizon, which could be capable of outputting more than 400 kW and charging a vehicle to 200-mile range in less than eight minutes. How Cooling Systems Work Liquid cooling works by pumping a fluid, called coolant, through pipes or tubes, absorbing heat and dissipating it away from critical components. This reduces the temperature of those critical components, including capacitors, inductors, and control circuits, leading to more efficient charging and longer product life. The coolant is typically water mixed with glycol to prevent freezing or boiling. High quality liquid pumps are essential for effective liquid cooling operations. Constant and consistent flow is required for these systems to function properly. This ensures heat is being adequately transferred away from the element while also keeping the coolant at an appropriate temperature. Reliability is also key, as leaked coolant could result in catastrophic equipment damage. Photo from Depositphotos.com Liquid Pump Experts KNF has extensive experience creating state-of-the-art diaphragm liquid pumps for a variety of OEM and process industry applications. These pumps are self-priming and dry run safe, with flow rates ranging from 0.018 to 12.4 l/min and pressures up to 16 bar (rel.). KNF pumps are suitable for use with a variety of liquids, including abrasive and corrosive media and offer clean and reliable operation. Because of this, KNF pumps are trusted in some of the most demanding applications. In addition to offering a wide range of liquid pump series, KNF also provides custom options for all liquid diaphragm pumps. Pump heads, valves, and diaphragms are all available in various materials, while hydraulic and electrical connections can also be customized. Several motor options are available. KNF’s modular design approach allows pumps to be tailored to specific applications and ensures customer needs will be met. Cooling is Critical More power is required for EV chargers to provide faster charging. However, more power also leads to more heat generated. This makes cooling, specifically liquid cooling, an essential part of their operations. This is especially true in the larger, publicly available fast chargers, which need to output huge amounts of power to charge vehicles quickly and effectively. Faster charging is important for increased adoption of EVs, but it is also directly correlated to excess heat generation. Many readily available cooling systems are unable to adequately cool EV chargers quickly or efficiently enough, leading to slower charging speeds, performance issues, and increased maintenance costs. Cooling is also important in EV charging station cables, which are required to transport large amounts of energy very quickly. Reaching adequate charging speeds requires cables that are capable of doing so, often resulting in large, bulky cables that can be difficult to maintain. Liquid cooled cables allow for faster charging and better performance while also being easier to handle. A New Era for EVs The latest data from the International Energy Agency estimates there are more than 40 million EVs on the road worldwide, an increase from about 26 million in 2022. Sales of electric vehicles are climbing worldwide, increasing substantially in North America, Europe, Asia and other parts of the world. Estimates vary, but predictions for percentage of global vehicle sales for EVs by 2030 are as high 86 percent. With this relatively new technology rapidly gaining in popularity, efficient and safe charging stations will be a necessity.

A behind-the-scenes look at the drive systems, automation, and comms that keep America’s #1 Broadway musical running smoothly. The Technology Behind The Lion King Musical’s North American Rafiki Tour A behind-the-scenes look at the drive systems, automation, and comms that keep America’s #1 Broadway musical running smoothly. Nicole Persun Stage Events Dec 16, 2025 Lead photo: Cheetah and Giraffes with the sun in the background | Photo by Joan Marcus and courtesy of Disney Since its debut in 1997, more than 114 million people have experienced the awe-inspiring artistry of Disney’s The Lion King on Broadway. The musical has won six Tony Awards, is Broadway’s third-longest running show in history, and is the highest-grossing Broadway production of all time. From the iconic first notes of “Circle of Life,” to the song’s reprise at the end of the final act, every element of the show — moving sets, puppets, dancers, actors, and the crew behind the scenes — must work together with precision. To celebrate The Lion King’s latest North American Tour, Entertainment Engineering spoke with Head Carpenter Kyle Techentin at Seattle’s Paramount Theatre about what goes into running this iconic and beloved show, and the technology that helps make it happen. Managing 23 Axes of Motion As the Head Carpenter, Kyle Techentin manages the setup, takedown, and ongoing maintenance of the show. “We start with a blank canvas,” he said. “The stage, lighting, hardware — all of it is ours.” The show never stops, so the production owns duplicate sets: one for the current city, and one that travels to the next location on the tour. “If something breaks,” Techentin explained, “we send it to the upcoming city to be maintenanced, so that it’s ready for the next stop.” This strategy helps keep the tour running continuously without unforeseen breaks. The Lion King musical has gone on multiple tours since its inception, with slightly different set configurations evolving over time to suit the needs of the locations it visits. The show is currently touring North America on their Rafiki Tour; the tour is open-ended, with cities currently announced through the end of September 2026. “There was actually more automation in the Gazelle Tour,” Techentin said, referring to the previous tour. “We cut the set down by about four feet to be able to fit it into smaller theaters.” This resulted in more manual set pieces and fewer electronically-operated elements — but there are still plenty of ways that technology fits into the show. The production itself has 23 axes of motion. “Anything that moves is considered its own axis,” Techentin explained. Pride Rock — a motorized staircase that travels across the stage on a track circuit system — is considered one axis of motion. The grasses — props with wooden bases that also move across the stage on the track — are another. The diaphanous fabric sun is its own axis, too. Company of The Lion King on Broadway during “Circle of Life” | Photo by Matthew Murphy and courtesy of Disney “There can be up to thirty-six actors onstage at a time, and many of the costumes greatly hinder the actor’s ability to see,” Techentin said, emphasizing the importance that everything runs according to plan. All axes must move with precision and reliability to ensure a safe environment for the actors and crew — and an unforgettable experience for the audience. Motion Control Pride Rock is perhaps the most iconic and recognizable part of the set, traveling out from the wings and turning in slow circles while the actors move through a scene. Its path is operated by a circuit track system in the stage that incorporates pneumatic switching units and eleven magnetic sensors. Inside Pride Rock, there’s a battery powered friction drive that controls its speed and timing as it moves along the track. A top-down camera allows a stage manager to monitor its progress in relation to the actors onstage. Peter Hargrave as Scar atop Pride Rock | Photo by Matthew Murphy and courtesy of Disney Entertainment Engineering also got an inside look at the mechanical wildebeest “herd” that is used to indicate the fateful stampede scene toward the end of Act I. As Simba runs from the stampede of wildebeest, there are three visual elements used to create a sense of depth onstage. First, in the background, a piece of fabric painted with tiny wildebeest rotates on a wheel to give the illusion of the herd running toward the audience from a distance. Then, in the middle ground, is a motor driven “herd,” which consists of multiple wooden wildebeests mounted on rotating arms. If there’s an error, the crew can flip a switch to “kill the beast” and operate it manually. Finally, in the foreground, actors in large wildebeest masks crowd the stage. It’s an intense moment in Simba’s journey — but it’s also an intense part of the musical for the crew due to the various set axes happening simultaneously. Closeup photo of the mechanical, motor-driven wildebeest “herd” taken by EE Staff with permission. This combination of set design, motorized components, and actors all add to the grand scope of one of the most pivotal and emotional scenes in the musical. How it All Comes Together It takes about 120 people — including actors and behind-the-scenes crew — with a minimum of three stage managers (there are five on staff) to run the show on any given night. Techentin manages many of the moving parts at his onsite automation desk that incorporates a Blackmagic Design control system and software used to monitor all of the set axes. The backstage support crew stays in touch using a professional-grade, multi-channel intercom system from Clear-Com, known for their complete connectivity and effortless scaleability. Techentin relies primarily on Hudson Scenic for much of the motion control and automation components, including custom jobs when required. “They get us whatever we need,” Techentin said. When watching Disney’s The Lion King Musical, it’s easy to get swept away in the incredible set designs, puppets, costumes, and superb acting. The technology might be subtle, but the seamlessness is intentional. From friction drive motors, to all-LED lighting, to CO2 “geysers,” and more, all the components — and the crewmembers who operate those components — are an essential part of the magic. The result? A truly unforgettable experience.

Coco Robotics partners with Prime Video and Omnicom to promote Eddie Murphy film Delivery Robots Used to Market New Film in LA Coco Robotics partners with Prime Video and Omnicom to promote Eddie Murphy film Film and TV Sep 1, 2025 Coco Robotics, an urban robot delivery company, partnered with Prime Video and Omnicom to promote The Pickup , a heist comedy film starring Eddie Murphy, Pete Davidson, and Keke Palmer. Coco Robotics was founded in 2020 and brings zero-emission deliveries in the U.S. and Europe through robot delivery. In a new campaign, the robots will be doing double duty, serving as marketing devices for the new film. Marketing with robot delivery The campaign launched July 21 and repurposed Coco's Los Angeles fleet of “robocouriers,” which are urban delivery robots, into marketing bots on the streets of LA, or as they call them, “immersive mobile brand activations” that blend entertainment and technology. As part of the campaign, Coco wrapped its LA-based mobile robots in Prime Video and film branding, designed “to evoke the film's iconic armored money trucks,” according to a press release. The campaign is intended to play on the film's central theme while it turns the robots into an extension of the film's story. The robots play voice lines from the film when deliveries are picked up, “turning each vehicle into an in-world character that expands the cinematic universe from screen to sidewalk.” So, Coco's robots deliver food, but also generate “broad exposure” that the company says rival traditional marketing methods, such as billboards. “Unlike static ads, Coco's robots draw eyes wherever they go - making them an attention-grabbing ad surface in any city that naturally sparks filming and sharing,” said the company in a press release. See Coco robot in action The visibility is powered by a combination of proprietary impression-tracking technology and OOH measurement tools. "This campaign shows how our robots can amplify brand storytelling in real time," said Josh Dubin, Head of Ads at Coco Robotics. "It transforms routine deliveries into personal, one-to-one brand experiences that connect with consumers in a natural, memorable way." This type of out-of-home advertising is something that some believe will be more common in the future. "We're always looking for ways to push boundaries and create media moments that people haven't seen before," said Elizabeth Boone, Senior Associate in Emerging Platforms and Partnerships at Omnicom Media Group. "This campaign is a glimpse into the future of media. It's a perfect example of a unique integration of robotics, storytelling, and neighborhood-scale visibility that can come together to bring a movie to life in the real world." The campaign also includes a custom commercial using Coco's delivery robots in a heist scene from The Pickup . Source: Coco Robotics Previous Facebook LinkedIn Copy link Next

Building a large interactive exhibit took insight, innovation, and the perfect systems to get it right. Volcanoes Explode on Interactive Table Exhibit Building a large interactive exhibit took insight, innovation, and the perfect systems to get it right. Edited by EE Staff Museums Sep 12, 2025 Ideum recently completed an interactive exhibit for the Volcano Discovery Center located inside the Valles Caldera National Preserve. For 1.25 million years, Valles Caldera has been shaped by dramatic geological events, thriving ecosystems, and a rich tapestry of human history. These stories unfold across the 89,000-acre landscape and span vast stretches of time. To represent this significant landscape, Ideum, in collaboration with the National Park Service, created a 12-foot topographic relief map as a canvas for this rich history to be projected upon. Immersive Technologies Suspended above the map, a 4K projector brings the table to life with projection-mapped sequences that engage multiple visitors at once. Synchronized RGB lighting washes over the walls in colors, while a 6.1 surround sound system with a 15-inch subwoofer creates a dynamic audioscape that can be felt. The show control system ties into motorized roller shades that darken the room every hour for the signature volcanic eruption sequence, transforming the exhibit hall into a fully immersive, cinematic environment. All photos courtesy of Ideum. Interactive Touch Screen Displays While the large map table captivates groups, the experience is designed for multiuser interaction. Four Ideum-built 34-inch 5K UltraWide Presenter touch screen displays surround the perimeter of the table, giving multiple visitors simultaneous control of the projected animations. Each station offers games and activities tied to one of four themes: Cultural History: Traces human activity from archaic-period settlers to the present day, developed in collaboration with 38 tribes and pueblos to honor their enduring cultural connections to the Caldera. Geology: Features a scrubbable geologic timeline where guests can witness the Caldera’s primary eruption 1.2 million years ago, along with the formation of lakes, lava domes, and other dramatic landscape changes. Ecology: The exhibit’s most extensive library of animations allows users to visualize wildlife migration patterns, plant communities, watersheds, and wildfire impacts across the preserve. Scientific Discovery: Explores the scientific research that has occurred in the region, including paleomagnetics, geothermal research, and seismic monitoring efforts. Exhibit Design and Fabrication The Ideum team starts work on a project with an exhibit design phase where they collaborate closely with the customer to design an immersive digital experience that will be engaging for visitors of all ages. Using Geographic Information System (GIS) data provided by the National Park Service, the Ideum exhibit fabrication team created the true-to-life scaled model of the Valles Caldera landscape. The CNC topographic relief map model, exhibit base, and screen mounts were created entirely in-house. The floating screen mounts were a particularly fun engineering challenge—the end result being a low-profile hidden mount meant to fade away into the table. The mount is tied off to the center ring of the exhibit, allowing for structural rigidity and strength even under the weight of visitors leaning or hanging on the screen. All photos courtesy of Ideum. The topographic relief map, spanning 12-feet in diameter, was fabricated in sections using 3D milling operations on a CNC machine. The map surface was machine-milled from high-density foam, then coated with epoxy for durability and finished with projection-enhancing paint. This hard-wearing surface is easy to clean and resistant to damage. The pieces were trimmed to the outer diameter of the circle and glued together. The map was then cut apart into five organic shapes that follow the natural landscapes of the Valles Caldera. Once on site, the map was seamed together with silicone and repainted. The table’s substructure, built from steel and wooden joists, is clad in Staron and Nevamar Armored Protection, creating an ultra-durable piece designed to endure the heavy use of public spaces while maintaining a refined appearance. Beyond the Exhibit Hall Since the newly branded Volcano Discovery Center sits more than a mile from the park’s main entrance, Ideum and the NPS created a way to draw visitors into the new interactive exhibit hall. At the Welcome Station, a 65-inch Ideum Presenter is programmed to be a Digital Docent providing maps, FAQs, and other day planning tools. Most notably, it includes a countdown clock inviting guests to witness the “volcanic eruption” of the table every hour, a feature drawn from the visitor anticipation that surrounds Yellowstone’s Old Faithful geyser.

An innovative approach to teaching music brings music education and technology together.  Violins Too Expensive? School Superintendent Turns to 3D Printing An innovative approach to teaching music brings music education and technology together. Joe Gillard Cool Stuff Sep 23, 2025 Here’s a story at the intersection of entertainment and engineering that will tug on your heart strings, so to speak. A school superintendent in Pennsylvania, Laura Jacob, noticed that students from low-income families had difficulty purchasing violins for music, and came up with a solution inspired by something she had heard of an orchestra doing: 3D-printing instruments. In the past five years, Jacob has 3D-printed 200 violins that are free for students in a school where 70% of them are low income. Violins can be very expensive, even relative to other instruments. It can cost hundreds in rental fees for the families of students, if they want their child to have the opportunity to learn violin in school. Jacob started out with two 3D printers. She now says she has 34 of them, and students can learn to use the machines, too. “I’m not a computer scientist or an engineer by any means, but after a variety of failures, I found one that actually printed and it sounded good,” Jacob told CBS News. The violins are made from a template created by a company called Hova Labs. Beyond that, Jacob used real violin strings, a few additional wooden parts, and then added modified guitar pegs. Hova Labs violin template for 3D printers The whole process takes about three days to finish a violin. If the instrument breaks (probably a strong possibility with schoolchildren), they can easily be fixed. As a fun added benefit, the 3D-printed violins can be made in different colors, which might make the instrument more interesting for kids. Prusa 3D Printers The Prusa XL 3D printers are designed for precision. According the company website, “the precision tolerance of a well-assembled Original Prusa printer is 0,1 mm on the Z-axis and 0,3 mm on X and Y.” And the company says that calibrations can be done to further improve the result. “It can be as little as 0,05 mm on all axes, after making additional calibrations such as the Extrusion multiplier calibration and Extruder linearity correction.” Prusa XL 3D printer The magnetic heatbed can hold a two-sided flexible spring-steel sheet, for removal of printed objects from the print surface, according to the product page for the Prusa XL. There are six varieties of sheets for the Prusa XL: smooth, powder-coated textured, PA Nylon, PP, and HighTemp, all of which serve a specific type of 3D-print job.

Designed to operate in various environments where human-machine interaction is essential, this humanoid robot provides versatility, intelligence, and is fully modular. Reachy the Open-Source Robot is Designed for Research and Industry Designed to operate in various environments where human-machine interaction is essential, this humanoid robot provides versatility, intelligence, and is fully modular. Edited by EE Staff Cool Stuff Jan 6, 2026 Reachy 2, from Pollen Robotics, was designed to adapt to a wide variety of uses and allows users to choose from several configurations. Its natural expressions and gestures make it an intuitive and engaging robot, capable of integrating into social environments. The robot’s fluidity is based on the company’s key innovation, Orbita, the bio-inspired joint system. The Orbita 3D is mounted to the robot as the wrists and neck, allowing harmonious and smooth movements with a wide range thanks to its three degrees of freedom. Similarly, the Orbita 2D, integrated into the elbows and shoulders, articulates via two degrees of freedom. The Orbita 2D is design to support loads of up to 3 kg. Image courtesy of Pollen Robotics. Reachy 2 is equipped with a Python SDK and is based on ROS2, offering researchers and developers an open and flexible programming environment. According to Elsa Kervella, Sales and Marketing Director at Pollen Robotics, “We designed Reachy as a platform: researchers can integrate their own algorithms, and developers can enrich the software.” Reachy even includes a teleoperation feature—remote control—opening up additional prospects for difficult-to-access environments or those requiring great precision. With a virtual reality headset, an operator can control the robot's movements in real-time as well as teach it new movements. This learning capability allows Reachy to reproduce learned gestures autonomously. Image courtesy of Pollen Robotics. The open-source approach is a central pillar of Pollen Robotics' identity. By making Reachy's plans and resources public, the company offers the global community an opportunity to customize and enrich the platform. This choice promotes collective innovation, aligned with the goal of democratizing access to useful robotics. "This not only allows our customers to adapt Reachy to their needs but also a global community to advance the technology, " said Kervella. Reachy was designed to appeal to both the academic world and industrial world. In prestigious institutions like EPFL or Cornell University, it is used to explore human-robot interaction and machine learning, pushing the limits of artificial intelligence in real conditions. In industry, its modularity allows it to adapt to complex environments, whether for cobotic tasks or specific simulations. When Pollen Robotics sought to push Reachy's limits, the company found a solid partner in maxon. The two teams closely collaborated to meet a challenge: adapting the components to demanding environments while respecting the robot's design and modularity constraints. Integrating the motors into the Orbita joints was a challenge as it was necessary to reconcile performance, compactness, and reliability while respecting Reachy's humanoid design. maxon met this challenge with a series of integrations including different motors, gearmotors, and sensors. For example, the maxon EC-45 flat motor featured an optimized winding design and powerful magnets. Its efficient heat dissipation enabled continuous operation at high performance levels while its flat design facilitated integration in confined spaces. The MILE inductive encoder was the perfect complement to the flat motors, offering high resolution and precision. The inverted-signal encoder was extremely resistant to magnetic and electric fields, as well as to dirt. It was directly integrated into the motor. GPX32 gearboxes offered over 90% efficiencies to ensure smooth and efficient movements. Their robustness ensured reliable handling, even under demanding conditions. From left to right: EC flat, ECX torque, GPX gearhead. Images courtesy of maxon. Additional components included maxon’s ECX22torque motors and GPX22C gearboxes. Compact and powerful the motors provided exceptional torque densities for precise motion, while their iron-core windings and multipolar design guaranteed the optimum energy efficiency necessary for dynamic, real-time movements. The gearboxes delivered exceptional power transmission, and their modular design made it possible to create customized solutions for customers. According to Kevin Schwartz, Sales Engineer at maxon, “The compactness and performance of the motors were essential to respect Reachy's humanoid design while increasing its load capacity.” Overall, the integration of maxon solutions has pushed the limits of Reachy, making it a platform as powerful as it is modular.

Rushed and dangerous scenarios require equipment that's safe and reliable. Here's how the aerial ladders on firetrucks just got safer. Fire Trucks Get a Ladder Safety Upgrade Rushed and dangerous scenarios require equipment that's safe and reliable. Here's how the aerial ladders on firetrucks just got safer. Edited by EE Staff Cool Stuff Nov 17, 2025 Amity Fire & Safety serves the Fire & Equipment industry by producing swivels, telescopic waterways, weldments, machined parts, and pins for extremely demanding applications. Their international customer base includes industry giants such as KME (Kovatch Mobile Equipment), Pierce Manufacturing, and Rosenbauer. Amity’s customers manufacture the fire trucks that are seen at local fire departments around the world. KME custom manufactures the broadest family of aerials in the fire service and incorporates IQAN E-Control™ (motion control system) in their trucks to ensure a high level of safety. Ladder base swivels allow for rotation of the aerial ladder while acting as a pass-through for water and continuous hydraulic and electrical circuits. The position of the aerial ladder on a fire truck needs to be monitored to reduce risk of injury and damage to equipment. Although Amity used limit switches to monitor whether the ladder was within certain degrees of rotation, the proximity switches still couldn’t monitor the accurate position of the ladder within that range. Safety swivel side and top view. Images courtesy of Advanced Micro Controls, KME, and Amity Fire & Safety. Without knowing the absolute position of the aerial ladder, damage or injury can occur in several ways. Trucks could tip over when the ladder’s range of movement is exceeded. This could happen during a short jacking operation where a narrow jack spread is used to avoid obstacles such as parked cars. Damage can also occur when bringing the ladder to cradle position. When the ladder is brought back into the resting (cradle) position, misalignments can damage the cradle ears. On mid-mount ladders, pump panel damage can occur when the aerial ladder is brought below grade (too far down). Outrigger jacks fully extended. Images courtesy of Advanced Micro Controls, KME, and Amity Fire & Safety. Accurate Positioning By using an absolute analog DuraCoder®, Amity is able to acquire the accurate feedback they need. The DuraCoder recognizes where the ladder is within the 0–360 degree revolution without guesswork. When the ladder is at a low angle, the operator is now capable of automatically stopping rotation at a pre-set point known to eliminate risk of damage to the body of the truck and injury to firefighters during a rescue operation. When KME upgraded to their Parker IQAN™ (motion control system), they realized that the grey scale encoder they had initially specified would no longer meet their voltage output requirements. Additionally, an excessive amount of mathematical programming was required with the grey scale encoder; and together, Amity and KME set out to find a more efficient solution. “If we want to be successful, we have to get to that next level.” DuraCode® absolute encoder. Images courtesy of Advanced Micro Controls, KME, and Amity Fire & Safety. Signal Changes After reviewing all of their options, KME contacted Amity with the solution: an AMCI DuraCoder with integrated cable. The DuraCoder’s analog output signal eliminated much of the mathematical programming that was necessary with the grey code encoder. With the integrated cable, KME no longer needed to produce their own cable, simplifying wiring and installation, and ensuring the IP67 sealed rating. The DuraCoder is installed in an area of the truck that is exposed to water mist during firefighting, high pressure wash downs, and airborne contaminants from smoke and ash. AMCI’s DuraCoders are designed to provide consistent reliable feedback while preventing water and contaminant ingress. With the DuraCoder, KME’s IQAN “E-Zone™ system stops rotation or elevation of the ladder when the operator attempts to position the ladder in a pre-defined zone (cab avoidance, body avoidance, and short jack operation). This eliminates the possibility of cab or body damage and makes operation of the device on the short jack side of the vehicle safer, according to the KME product brochure. Amity’s concerns when selecting an encoder included its ability to withstand heavy shock and vibration caused by the truck’s engine, onboard generators, and road vibration. The DuraCoder is resolver based, meaning that it was designed to provide absolute position feedback without plastic disks or magnetic components, enabling it to withstand high levels of shock and vibration. Amity Swivel with AMCI DuraCoder. Images courtesy of Advanced Micro Controls, KME, and Amity Fire & Safety. The optional 5/8-inch stainless steel shaft boasts exceptional shaft loading, and the high shock and vibration rating provides reliability where most sensors fail. The IP67 rated product line comes standard with either a ¼-, 3/8-, or 5/8-inch stainless steel shaft and an oversized double row sealed bearing. Additionally, DuraCoder brand encoders are available in six different versions, including SSI, Digital, Analog, Incremental, DeviceNet, and Ethernet/IP. Amity was able to change out the original optical encoder for the AMCI DuraCoder quickly and easily. The units’ industry-standard mounting pattern made it easy to replace the existing encoders. While the standard lead time for the AMCI DuraCoder is three weeks or less, Amity could not wait that long. Because AMCI designs and manufactures their products in-house, they were able to expedite the process, sending the full shipment out within a few days. After an easy installation, Amity’s swivels were ready to be sent off to KME.

A student team gained valuable STEM experience by developing an underwater remote operated vehicle using commercially available industrial-grade components. Industrial Devices Used in STEM Project A student team gained valuable STEM experience by developing an underwater remote operated vehicle using commercially available industrial-grade components. Geoff Gardener, North Paulding High School Cool Stuff Jul 9, 2025 Exploration of both the deep sea and of outer space share a lot in common. Both are extremely unforgiving environments where it is very expensive to create manned vehicles to carry out missions. As automation has become more capable, robotics and unmanned remote operated vehicles (ROVs) are used to execute much of this work. Underwater ROVs operate in challenging environments, which means that industrial-grade automation products are a natural fit to support these designs. Also from EE: Escape Room Experience Uses Automation Tools Although, ROVs are controlled remotely by human operators, most have some degree of on-board automation, combining mechanical, automation, and other skillsets. To develop young talent to support this field, Monterey Peninsula College—via a grant from the U.S. National Science Foundation—has established a program called the Marine Advanced Technology Education (MATE) Center. MATE promotes marine engineering by inspiring and challenging students to learn and creatively apply STEM skills for solving real-world problems. Part of the program is the MATE ROV Competition, which offers five different contest classes, each based primarily on skill and not strictly by age group. At North Paulding High School in Dallas, GA, a number of students make up the “WhaleTech” team. Some of them have participated up to seven consecutive years, starting in middle school. Each year, the competition organizer publishes challenges and mock mission profiles simulating real-life conditions, with various restrictions. For example: dive to a pipeline simulation at a given depth, strategically remove a “bad” pipe segment, replace it with a new section, and bring the bad portion to the surface. The team builds a ROV to meet those challenges, and along the way they must act and present themselves as a professional company by developing technical documentation, conducting research, and selecting products. Throughout the process, the team must learn and follow safe practices, assemble and test the ROV and subcomponents, and even do a bit of marketing. The Details Many ROVs look a lot like aerial drones, with propellers arranged to provide thrust in various directions. Just as aerial drones use propellers to provide constant lift and control motion, an underwater ROV does the same, but it can also use an additional mechanism to adjust its buoyancy. Cameras and lights are common on ROVs, and many also have robotic arms and manipulators to perform tasks. Many of the monitoring and control needs mirror the types of functionalities needed by industrial automation control systems. AutomationDirect has a long history of supporting student STEM efforts, and this underwater ROV project exemplifies just how important it is for industry to support education. For the 2024 competition, the WhaleTech team needed to develop a well-controlled ROV with an extensible gripper. The buoyancy mechanism, gripper, cameras, propellers, and other components would need to be supported and arranged in a chassis, which meant that some design effort would have to be in parallel and iterative to achieve the functionality and create an integrated form factor. As part of the process, the team used cardboard mockups and 3D printing, and then they created many structural elements cut out from high density polyethylene (HDPE). The buoyancy engine is used to actively alter the buoyancy of the vehicle so the ROV can rise, descend, or stay at a fixed depth (Figure 1). A sealed cylinder compresses the fixed air volume, displacing it with water, which results in changing the overall density of the apparatus. Figure 1: The buoyancy engine consists of a specially modified pneumatic cylinder, driven by a stepper motor and an AutomationDirect SureStep stepper drive, to provide accurate control with minimal power consumption. (Photo courtesy of North Paulding High School.) After selecting an industrial-grade cylinder, the team needed a powerful yet controllable way to actuate the piston portion via a linear screw drive mechanism. After some trial and error, and investigation of technologies readily available from AutomationDirect, the team found that a stepper motor could do the job admirably. A stepper motor can continuously turn in either direction and be commanded in increments as small as 1.8 degrees per step, driven by an AutomationDirect SureStep stepper drive commanded by an Arduino nano. A stepper motor draws no power when idle, it works well within the available power budget, and there is no rebound when the target position is achieved. The buoyancy engine is also outfitted with a pressure sensor used to store depth data into the on-board computer, and a wireless transmitter to communicate this information to the surface computer for a graph display when the ROV surfaces. Similarly, the gripper assembly incorporates an AutomationDirect SureStep rotary stepper motor driving a screw shaft to provide the motion required to extend or retract a mechanism, which in turn opens or closes the gripper (Figure 2). Because this assembly must articulate, it is connected to the controller using a watertight flexible cable. Figure 2: The WhaleTech project team found the right cable assembly for the gripper by researching the AutomationDirect catalog where they found cut-to-length cable solutions that met their technical needs.

In previous competitions, the team had experienced issues with umbilical cables—running from the ROV to the surface—that were not flexible enough to allow precise movements in the water, or were insufficiently shielded and therefore susceptible to electromagnetic interference (EMI). To solve these issues, the team researched cables on the AutomationDirect website and found products with better flexibility and improved resistance to electrical noise. Further, the team occasionally used AutomationDirect’s phone support to iron out details. As a result of their design and execution efforts, the WhaleTech team won first place in the Ranger class of the 2024 MATE ROV Competition. While some members are graduating and moving on to new work and educational endeavors, a new crew will assemble next year and work to build upon their successes.

A rehabilitation of Atlanta’s historic Fountain of Rings earlier this year included the installation of a new, transformative technology that’s dramatically improved the water feature’s programming capabilities. Fountain Technology Transforms Iconic Water Feature A rehabilitation of Atlanta’s historic Fountain of Rings earlier this year included the installation of a new, transformative technology that’s dramatically improved the water feature’s programming capabilities. Theme Parks Sep 4, 2025 Cool Stuff Built nearly 30 years ago, the enormously popular LED-lighted show-style water feature comprises more than 250 manifold-mounted precision jet nozzles supplied by several large dry pumps. Designed to reflect the iconic interlocking Olympic rings, this choreographed display has become one of Georgia’s most photographed attractions, delighting guests with daily performances of synchronized water, lights, and music. Led by Texas-based fountain design firm The Fountain People, the comprehensive restoration effort included the installation of 256 new display nozzles and an integrated LED ring light fixture for dramatic color-changing effects. The project also added plug-and-play connections and a new water feature show panel with a touchscreen interface that allows operators to select among up to ten choreographed musical fountain shows.

Further improvements included modernized pump and filtration systems, fog system repairs, and remote access capabilities that give staff greater control over the fountain’s operation. Perhaps the most exciting addition brought by the renovation, however, was the installation of a new fountain valve technology that’s enabled vastly richer nozzle effects and choreographies, thrusting the historic attraction into a new, growing class of elite manifold-based fountains and water features. Until recently, manifold-based water features such as the Fountain of Rings used a water switch, a three-way valve installed at each nozzle that allows on/off nozzle sequencing. The ability to independently control spray height for each nozzle, however, has always required a distributed pump architecture where each nozzle is controlled by its own VFD-driven effect pump. This approach required extensive submerged electrical infrastructure but allowed for show flexibility where programmers could provide complex effects such as waves, variable height chase scenes, and more. Now, this same level of control is available among manifold-based water features. The Robotic Water Switch Developed by Texas-based aquatic robotics company SplashBotix, the SplashValve is a single-axis, fast-acting robotic valve that uses a specially shaped diverter to bring proportional nozzle height control to manifold-based water features for the first time. The Fountain People’s restoration effort marks one of the first and largest uses of the new technology, representing a new standard in manifold-based water feature design and programming. SplashValves are three-way valves installed at the nozzle, designed to divert incoming water to effect or bypass. Unlike water switches, however, SplashValves can also divert water to varying proportions of effect and bypass, enabling both on/off and spray height control. Capable of cycling up to four times per second, SplashValves marry the speed and on/off action of a conventional water switch with the height control flexibility of a VFD-driven effect pump.

SplashBotix is a division of ARM Automation, an industrial robotics and automation firm with more than 30 years of experience developing high-performance motion systems for semiconductor, aerospace, and factory automation. Unlike other technical suppliers in its industry, SplashBotix takes much of its design and engineering inspiration from the world of industrial automation. For this reason, the story of SplashBotix and the SplashValve challenges assumptions about where advanced robotics and automation principles can provide value—not just on factory floors, but in public and municipal spaces as well. Design Features The secret behind the SplashValve’s advanced flow control capabilities lies in its clever electro-mechanical design. Rather than using a pilot switch to control the flow of water, the SplashValve uses a specially designed, servo-actuated diverter. Set inside the SplashValve’s bore, the diverter rotates 90-degrees between effect and bypass, incrementally changing the nozzle spray height as it shifts its position. Fully enclosed, the SplashValve’s servo motor transmits motion to the diverter through magnetic actuation, a clever static-seal design that makes the SplashValve virtually leak-proof.

Composed mainly of 316 stainless steel and a proprietary blend of wear- and chemical-resistant plastics, the SplashValve also offers advantages over competing solutions when it comes to maintenance and durability. Effectively a one-inch diameter pipe when the diverter position is at full effect, the SplashValve allows most fountain debris to pass right through to the nozzle, making screen filters largely unnecessary. When clogs do occur, SplashBotix has made the diverter easily accessible for maintenance personnel, who can remove the diverter from the magnetic coupling, clean the valve and return the diverter back to the SplashValve all in less than a minute. From a fountain engineering and design perspective, the SplashValve represents a major paradigm shift. By bringing proportional control to manifold-based systems, the SplashValve is enabling designers to deliver world-class shows without the cost, complexity and power requirements of installing hundreds of VFD pumps. For municipalities like Atlanta and other stakeholders, this means richer experiences for guests, safer public amenities, and less frequent, less costly maintenance.

Live production and signage workflow incorporates live social content into lively display screens Social Media Engages Recreational Crowd Live production and signage workflow incorporates live social content into lively display screens Brian Galante Sports Jun 4, 2025 The rallying cry of “Attention all sand addicts, duners, and dirtheads” resonated loud and clear in the YouTube event announcement for Polaris Camp RZR, one of the biggest dune gatherings of the year. It was the first serve in a social media volley that amplified the fan experience throughout the three-day recreation event. The annual event celebrates the sport and the machines, taking place at the Imperial Sand Dunes Recreation Area near Glamis, California. The location is roughly two hours east of San Diego in a region considered the Mecca of North American sand dune recreation. The reputation of the event and the region was enough to draw thousands of enthusiasts this year, driving everything from backyard quads to full-blown desert racers. Overnight, attendees transformed Glamis Beach into a massive campsite as the event prepared to open on Halloween day. Those preparations included the installation of three video walls and a fully loaded digital production facility. Alpha Sports TV, experts in delivering specialized broadcast content for sports and live events, provided the production front-end and handled content creation and delivery. This included playout of sponsor advertisements and more than 30 special features, as well as live content captured on a roving, wireless Sony HXC100 camera with embedded audio. “A lot of what we did involved processing literally terabytes of media files, primarily video, from many different sources,” said Andrew Allan, president of Alpha Sports TV. “We made sure that the high-quality content we processed was rendered in equally high quality with no artifacts, even though outdoor video walls are quite tolerant of high compression. We needed to make sure all the content, whether from an outside source or acquired live on-site, ultimately looked the same in terms of aspect ratio and overall quality.” Allan points out that many production companies can handle this, but Alpha Sports TV, with its history in Olympic Games and other high-profile events, was brought in for its expertise in integrating graphics, video, and data into live broadcasts and events. This was especially important for the social media aspect, which proved to be a major attraction and source of engagement for attendees. The social media gateway was opened courtesy of software from Bannister Lake, a graphics and broadcast automation specialist. Allan integrated Bannister Lake’s TweetOut and TweetOut Nano products into the workflow to keep screen content refreshed and dynamic. Allan ran TweetOut on the Ross Video XPression Studio platform, creating Twitter and Facebook routines for several different graphics layouts including insertion over the prerecorded Polaris features. This included full-page and lower-third layouts, the former of which could take advantage of TweetOut’s inline photo support. This means that the full-page graphics space was mostly reserved specifically for photos taken by attendees with their “feet on the ground.” Those photos were stored in the Flow database along with tweets and other data content, and made available for output into the lower-third layouts. Room to Spread The TweetOut Nano solution essentially offers users a compact form factor for integrating social media content into live broadcasts – especially ideal for temporary facilities where rack space is limited. Allan likens its size to “a few decks of cards,” noting that it’s very quick, reliable, and networkable. “We can conceivably have several different ‘content moderation clients’ networked into the switch, all providing their own social media contributions to the stream,” said Allan. At the Polaris event, the TweetOut software constantly polled Twitter and Facebook content based on search parameters, including several different hashtags provided by Polaris. The production team regularly received hits based on those hashtags. A built-in interface allowed for downstream editing of content that was raw or inappropriate. From there, the content went straight into XPression. That flexibility to moderate streams with simplicity also meant that Allan could focus on higher-end production aspects, including live camera feed monitoring and on-the-fly graphics creation. “I like to have all these different components broken out into modular functionalities, which is why we have TweetOut Nano dedicated to managing the raw data,” said Allan. “That way when there is someone on site who can help, we can put them in front of the Nano box to moderate the content. Everything that comes from the Nano into my Ross XPression has been pre-moderated. That relieves me from having to keep my eye on four different machines.” Flow Motion The complete workflow included transcoding tools from Handbrake and Adobe for format conversion, and a temporary site-wide satellite broadband solution for local WiFi device connections so that attendees and participants could engage and connect via social media. The combined output of video, graphics and social media was ultimately output through a Ross Carbonite switcher, which, along with the videowalls, Sony camera and RF hardware – including six antennae spread around the site for camera feed transmission – was provided under a contract with Screenworks. The broadband link was partitioned for private and public use. This ensured that Alpha Sports TV wouldn’t lose its slice of the bandwidth if attendees swamped the network. “Nano doesn’t require much bandwidth at all – it’s purely XML data, and as such doesn’t cause any bottlenecking in terms of data throughput,” said Allan. “It was essentially an input into the Carbonite switcher, networked with one of the laptops running XPression. We used a third laptop for standalone Xpression graphics, which were basically content layouts built in advance so we could quickly post updated event schedules.” Elsewhere, Allan notes that aspect ratio was an interesting challenge. All video content was delivered to Alpha Sports TV in HD 16:9, while the main giant screen was SD 4:3. To compensate, videos were formatted for HD and letterboxed to the screen to avoid loss of content. The screen's huge size allowed the letterboxing to be an acceptable compromise. Ultimately, turning the typical event production into a “SocialTV” experience was an important step. “You can very quickly tell when people catch on to tweets and social media activity on the screens, because the comments quickly increase in quantity,” said Allan. “If you make it clear that you’re looking for photos and things to accompany tweets, it comes fast and furious. That’s really what you want to see out of an event like this, and we had the right tools in place to out as much content as possible.” For more information: Alpha Sports TV Sony HXC100 Camera Bannister Lake (now part of Ross) Handbrake transcoding tools Adobe transcoding tools Previous Facebook LinkedIn Copy link Next

How this automated bowling system — created for testing bowling balls, lanes, and related equipment — was engineered. EARL the Bowling Robot Can Reproduce Virtually Any Throw How this automated bowling system — created for testing bowling balls, lanes, and related equipment — was engineered. Edited by EE Staff Sports Nov 17, 2025 Games When the U.S. Bowling Congress (USBC), the national governing body for bowling, approached ARM Automation with a request to develop an automated bowling system capable of reproducing virtually any type of throwing style to a high degree of accuracy, the company’s creative wheels started turning. In their quest to build the ultimate testing platform for balls, lanes, and related equipment, the USBC had approached several different machine builders and had evaluated using many off-the-shelf robotic systems to no avail. What had to be done is for the ARM Automation team to break down the many different challenges presented and come up with a solution that met all of the performance criteria—within a strict budget. The team had to consider multiple elements in a bowling test, including different ball masses, ball grip orientations, spin, velocity, release point, and throw vector parameters. Any single bowl requires specification and execution of up to over a dozen variables all interacting at once. The Enhanced Automated Robot Launcher (EARL) is essentially a purpose-built seven-degree-of-freedom robot and tightly calibrated control system that allows for precision motion (± 2mm) and split second (± 1ms) timing accuracy. That’s what was ultimately required of the system to provide throwing a bowling ball at speeds up to 25 miles per hour time after time for test after test. All images courtesy of ARM Automation. Some of the key attributes of EARL include high robot tip speeds, high precision motion, fast spin speeds of unbalanced balls, and a simple touch-panel setup with flexible programmability. EARL is built for portability and rigidity. It’s mounted on air bearings, which double as vacuum chucks to secure the frame while throwing the ball. One of the key challenges of the project was the development of a suitable combination ball gripper/spindle/release mechanism. Each ball must be captured in a user-defined grip orientation (gripper spin axis relative to the ball’s rotationally non-homogenous coordinate frame) and clamped with significant pressure despite small variances in allowable ball size. To achieve required ball spin speeds of up to 900 rpm, a spindle motor system was incorporated into the scissor like gripper apparatus. Finally, in order to achieve precise release points while traveling at maximum arm speed, the gripper mechanism needed to open in a manner that imparted no adverse motion to the ball’s instantaneous trajectory and needed to do so in a very tight window of time, ±1 millisecond. This free-release grip solution required that the clamp forces on the ball be almost instantaneously reversed. To achieve this function, the ARM team of designers created a reversible scissor mechanism which once set closed was held in place by a multi-stage hair trigger release. Once set, the clamping cylinder loading was reversed, which attempted to open the mechanism. This allowed a fast-acting solenoid—combined with an accurate look-ahead control scheme—to release the spindle jaws at precisely the right moment and see that they swung wide and clear of the departing ball. EARL’s capabilities were so repeatable that it limited its own ability to bowl a perfect game. During an initial competition against a top professional bowler, EARL’s programmed perfect throw rubbed a dry streak on the oiled lane, which resulted in a progressively decreasing score. Tom Frenzel, USBC Senior Director of Equipment Specifications said, “Something I say about E.A.R.L. when I showcase him is: Due to the range of release variables E.A.R.L. can be adjusted with, it gives us a bowler for our research that can emulate any bowling style from the standard league bowler hobbyist all the way up to the top-level professionals by just pushing a few buttons. That allows us to study how our equipment specifications affect all levels of the sport.” Bonus video of EARL playing against Chris Barnes, 2007–2008 PBA Bowler of the Year: For more information, visit ARM Automation .
