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. Image courtesy of SplashBotix. 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 .

As differentiating features of automobiles are increasingly defined by software, OEMs are transforming their development processes from hardware- and component-centric to software-centric approaches. Complete Automotive Design Through Virtual Prototyping As differentiating features of automobiles are increasingly defined by software, OEMs are transforming their development processes from hardware- and component-centric to software-centric approaches. Gunnar Braun, Technical Product Manager, Synopsys and Stewart Williams, Segment Mamagement Director, Synopsys Cool Stuff Jul 29, 2025 In the race to develop software-defined vehicles (SDVs), automotive manufacturers (OEMs) and their suppliers are facing pressure from all angles. With vehicular codebases often exceeding those of commercial aircraft, OEMs must wrangle enormous complexity while shortening developing cycles. In addition, companies must deliver frequent software updates throughout the vehicle’s lifecycle, which continually assures quality, safety, security, and reliability. Further, cost pressures are enormous. These challenges demand faster, more rigorous software development, testing, and validation. While traditional hardware-in-the-loop (HiL) testing rigs are still a mainstay for system validation, their expense, latency, and inflexibility are increasingly at odds with the agility required by today’s automotive software development practices. To enable earlier and more efficient software testing and validation, the industry is adopting cloud-based development practices and the use of virtual prototypes. Cloud-native development Automotive software is simultaneously becoming more expensive and central to a car’s identity. Infotainment, advanced driver-assistance systems (ADAS), traction control, and even powertrain management are all shaped by lines of code. The growing adoption of electric vehicles (EVs) and the push toward fully autonomous transport have further increased the role and importance of automotive software. The shift from hardware-centric to software-centric vehicles means that OEMs and suppliers must rethink their development models. The IT industry pioneered cloud-native development approaches, leading to web applications and Software-as-a-Service (SaaS) solutions that are quickly delivered and continuously updated. These approaches involve incremental development and a strong emphasis on automation. DevOps practices further bridged the gap between the software development process and its operational deployment environment. Thanks to technologies such as containerization, testing cycles are now performed and automated in a production-simulated environment. This is one of the key challenges for OEMs and suppliers adopting cloud-native methods for SDV development: The replication of the operating environment — the vehicle — when developing and testing software. While the cloud provides virtually unlimited compute and collaboration resources, physical hardware—the ultimate destination for automotive software—often lags behind in availability. Teams often wait months for electronic control units (ECUs) to be ready for initial testing and validation. If hardware revisions are required, it extends the waiting period before OEMs and their suppliers can fully test their software at scale. All photos courtesy of Synopsys. Virtual prototypes accelerate automotive software development Virtual prototypes are models of target hardware that are used for software development, testing, and validation — before the hardware is available. Referred to as electronics digital twins (eDTs), these virtual prototypes simulate the behavior of automotive compute platforms; enable continuous software testing, integration, and delivery (CI/CD); and minimize the reliance on hardware and eliminate associated delays. Virtual platforms are used throughout the embedded software industry for starting software development before hardware is available, which results in a significant time-to-market advantage. A notable example is the open-source community’s use of QEMU, an emulator that allows open-source software stacks to leverage cutting-edge Arm CPU features well before the corresponding hardware is available. But traditional emulation-based tools were never designed for the complexity of modern automotive processors, such as Arm’s Cortex-A720AE, or the runtime demands of continuous, cloud-based software development. With Synopsys’s introduction of Virtualizer Native Execution, they are addressing these limitations and enabling Arm embedded software to be executed directly on Arm server CPUs—in the cloud, with no emulation or hardware required. This means developers can run workloads at the speed of the eventual hardware, roughly 100x faster than traditional instruction set simulators, while retaining the benefits of virtual prototypes and full compatibility with the existing ecosystem of models, tools, and workflows. Here are some of the technical and operational impacts: Software teams can validate complex system-level behaviors early and often, reducing the dependency on HiL rigs during the development cycle. With architecture parity between cloud and vehicle CPU (via Arm’s instruction set), developers can use the same development tools to significantly reduce workflow complexity. Native execution on Arm-based cloud instances, such as AWS Graviton servers, enables continuous DevOps and CI/CD pipelines, with virtual prototypes providing the critical link between development and operational environments. Leveraging the SOAFEE reference architecture An essential part of this puzzle is the SOAFEE (Scalable Open Architecture for Embedded Edge) initiative. Led by Arm and other industry stakeholders, SOAFEE provides a standardized framework and reference architecture—based on the principles of modularity and orchestration—for SDV workloads. By adhering to common standards like SOAFEE, the ecosystem of automotive OEMs, suppliers, and technology leaders can increase interoperability and reduce vendor lock-in. All photos courtesy of Synopsys. At Embedded World 2025, while in collaboration with Arm, Synopsys demonstrated how virtual prototypes, SOAFEE reference architecture, and cloud-to-edge software development come together: Leveraging Synopsys Virtualizer Native Execution in an AWS cloud environment, the demonstration featured an open-source autonomous driving workload running on top of the SOAFEE edge reference stack. Executed at real-time speed, the virtual prototype was approximately 100x faster than a comparable QEMU-based simulation. The demonstration showed how virtual prototypes replicate the structure of an edge device with sufficient granularity to validate real-world functionality and software behavior, while remaining scalable and shareable across teams and geographies. While the technical underpinnings are compelling, the business value of virtual prototypes and cloud-native development is just as important. Cloud-based workflows are becoming a prerequisite for meeting time-to-market expectations in a world where vehicle features are continuously updated via over-the-air (OTA) software pushes. Synopsys’s collaboration with Arm and other SOAFEE partners is ongoing, and forthcoming advances to Virtualizer Native Execution will enable more complex scenarios and system-level parity. This includes better support for real-time behavior, safety domains, and full-vehicle E/E system integration. In the meantime, the automotive industry has a powerful foundation on which to build.

The most powerful standalone telescope in the world uses modern miniature drives commonly used in industrial automation World's Largest Binoculars Allow Astronomers to Achieve Sharper Images The most powerful standalone telescope in the world uses modern miniature drives commonly used in industrial automation Edited by EE Staff Cool Stuff Nov 3, 2025 Astronomers are particularly interested in setting sights on distant galactic systems, young double stars, and newborn suns. A definitive way to proceed with such goals includes the Large Binocular Telescope (LBT) located on Mount Graham in Arizona. The telescope has a height of over 20 meters and weighs over 600 tons and is the shape of an outsized pair of binoculars. The LBT’s two reflectors each have a diameter of 8.4 meters, and together they make up an approximately 100 sq. meter dish for collecting light. In this way it can even collect the radiation from weakly illuminated objects at the limits of the universe being observed. The interaction of the two reflectors mounted 14.4 meters apart provides the telescope with a resolution that would correspond to that of a pair of binoculars having a diameter of 23 meters. Each reflector resembles a giant "honeycomb" made from borosilicate glass and weighs 15.6 ton. All photos courtesy of Faulhaber. The design of the telescope and its integrated optical systems provides scientists with a high level of flexibility when making their observations. That way they can use each of the reflectors independently of one another to view the same object, but also study different objects by tilting the viewing axes slightly or use both reflectors to observe the same object at maximum resolution. In order to achieve the unusually high definition, the rays of light reflected by each reflector are superimposed—brought to a state of interference. Consequently, the resolution is nearly ten times better than with conventional standalone telescopes. However, the requirement that has to be met to ensure the LBT works smoothly is that individual components made in the three partner countries—the US, Italy, and Germany—interact perfectly and under adverse conditions. After all, Mount Graham is approximately 3,300 meters high. The climate is characterized by temperatures below freezing, humidity of up to 90%, and extreme temperature fluctuations. Positioning unit for interference generation If a high-resolution image is to be created by the generation of interference, the optical assemblies attached to the two reflectors for bundling and superimposing the reflected light have to be positioned with an accuracy of 5 µm. For this purpose, the Feinmess company in Dresden (Germany) developed a three-axis positioning system that moves the appropriate optical system on the two reflectors of the LBT into the correct position. Horizontally, distances of up to 200mm have to be covered (longitudinal positioning), and vertically, for focusing purposes, there are distances of up to 50mm. At the same time the optical assembly has to be rotated through an angle of up to 36 degrees. In order to ensure the required positioning accuracy, the system has to operate with as little play as possible. That is why great importance is accorded to the drives on the spindles. In this case, the drive solutions included traditional bell-type armature motors with coreless rotor coil from FAULHABER. The small DC drives operate reliably even under hostile ambient conditions such as ambient temperatures between -30°C and +125°C. The devices are not affected by a high level of humidity (up to 98%) when specified appropriately. An important basic criterion for motor selection included instant, high torque starting for the DC motor after application of voltage, which ensures a direct response to control signals. The coreless copper coil allows an extremely lightweight motor design with a high efficiency of up to 80%. The motors used on all three spindles of the positioning system have a diameter of 26mm and are only 42mm long. At speeds of up to 6,000 rpm they provide a power output of 23.2 W. All photos courtesy of Faulhaber. A Compact Unit In the LBT application, the motors were combined with two-stage planetary gearheads with a ratio of 16:1. Flanged to the end of the motor, gearhead performance is extremely impressive, not only due to their compact design but also because of their steady running and durability. Gearhead backlash was factory optimized for use on the positioning system. Instead of the values of about 1 degree, customary on standard gearheads, these planetary gearheads have a backlash of only 12 angular minutes, measured at the output shaft. Knowing the actual position of the motors is an essential prerequisite for precision positioning. With the positioning systems employed on the LBT it is detected at each motor by an optical pulse encoder that generates 500 pulses per revolution. Using a metal disk, a transmitted-light system generates two phase quadrature output signals. The index pulse is synchronized with output B. For each of the three channels there are inverted complementary signals. The pulse encoder is fitted to the free end of the motor shaft and fixed with three screws. Supply voltage for the pulse encoder, the miniature DC motor, and the output signals are connected via a ribbon cable and a 10-pin connector. Since the drive units, comprised of the motor, gearhead, and pulse encoder, are extremely compact, they are easy to integrate into three-axis positioning systems.

How Tolomatic accurately positioned a large and heavy camera in a very tight space. Camera Positioning System for Theme Park How Tolomatic accurately positioned a large and heavy camera in a very tight space. Terry Persun Theme Parks Jun 12, 2025 When a well-known amusement park required a digital camera positioning system for a popular attraction, they turned to Tolomatic for a solution. The major attraction required the positioning of a large and heavy, 25-pound camera to happen in a very limited space. The solution could not use a separate control cabinet or extensive cabling, yet the motion control drive components were required to maintain an overall pleasant attraction experience. In addition, maintenance free operation was highly desirable. For the final solution, the engineering team selected to use the JVL integrated servo motors integrated with the Tolomatic ERD electric cylinder actuator. JVL’s innovative motors are integrated with the drive included, providing a flexible motion control solution that can exist outside of the control cabinet. Tolomatic’s ERD series is an economical electric cylinder that is compatible with many NEMA and metric mount stepper and servo motors to create a flexible and powerful, yet cost-effective electric cylinder solution—over the use of traditional pneumatic cylinders. ERD actuators are available in three body sizes, offer force/thrust capabilities up to 500 lbf (2.2 kN), and stroke lengths up to 24 inches (610 mm). IP67 and IP69K options are available. The Tolomatic and JVL camera positioning system for the amusement park application was chosen based on its compact size, maintenance-free ball screw design, and ease of system integration. Offering a very simple setup and configuration software added to the ease of implementation. The system incorporates a closed loop positioning configuration to ensure proper positioning of the camera every time and with minimal electric components. The final application stroke length is three inches which happens within a speed of 6-8 inches per second. For the customer, Tolomatic provided an all-in-one actuation solution that also eliminated the need for additional components. The easy, clean actuator installation with minimal maintenance requirements provided an enhanced attraction aesthetic by eliminating the need for separate control enclosures.

Flexibility and Stability 35North Studios selected an OptiTrack system after evaluating the different types of motion capture technologies including how each one would support their vision for the new virtual production stage, both immediately, and long term. “We wanted our LED ceiling to be a reflective surface at all times, which automatically ruled out inside out camera tracking ,” Fairfax said. “If we had to place a bunch of trackers on the ceiling for positional tracking, then that would mean they would be visible in the reflections. We wanted to avoid that.” Because of their need for more creative latitude, their search eventually landed on optical camera tracking and the OptiTrack system. “For us, it’s all about flexibility and stability,” Fairfax said. “With an OptiTrack system, we are not tied solely to virtual production. For example, if we decide at a later stage to invest in an animated feature that needs motion capture, we can do that.” The flexibility of OptiTrack proved beneficial when 35North Studios wanted to expand its tracking volume. “We decided to also track our side walls to Unreal, which allows us to avoid having to remap everything every time we move one of those mobile walls,” Fairfax said. “That wouldn’t be possible using different tools.” The decision to integrate an OptiTrack system was also based on 35North Studios’ set up to use two ARRI cameras in their virtual volume and to be able to track both at once. OptiTrack provided the ability to track props, which the company can build into an active tracker and send to Unreal in real-time. “It’s such a multipurpose tool,” Fairfax said. According to Fairfax, OptiTrack provides several other advantages—the system is user-friendly, the equipment is dependable, and the software is easy to learn and understand. But what stands out the most is that the technology is virtually unnoticeable. “I haven’t had to worry about it being visible once on set,” Fairfax said. “It’s never a thought in my mind.” For information: OptiTrack Planar Epic Games ARRI Brompton Technology Previous Facebook LinkedIn Copy link Next

EE Staff Theme Parks Oct 7, 2025 Sports RPM Raceway, an immersive go-kart and entertainment destination with U.S. locations on the east coast, is merging go-kart racing with the familiar party video game experience of popular games such as Mario Kart. Kart Klash, which launched in September, is the first of its kind to do this type of interactive go-kart experience, according to RPM, which they call and “arcade-style battle where speed meets strategy.” Driving go-karts equipped with F1-inspired steering wheels and LED displays, racers collect and activate power-ups, including missiles, MPs, TNTs, boosts, and shields while navigating the track. Similar to the Mario Kart format, “mystery boxes” and “boost zones” add a layer of tactical gameplay, where each decision can make or break the race and give the edge needed to pass competitors on the track. “Kart Klash isn’t just about recording your fastest lap, it’s about outsmarting your opponents and crossing the finish line first,” said Andrew Farage, CEO and Co-Founder of RPM. “We’re rolling out a social reinvention of go-karting that blends the thrill of racing with the interactivity of gaming, appealing to a demographic that may prefer strategy over raw adrenaline.” In April, RPM was awarded the Guinness World Records for Longest Indoor Multi-Level Go-Kart Track in the World. The convergence of software and karting Built on RPM’s R-TECH platform and developed in partnership with SODIKART, each kart is equipped with an LED heads-up display that delivers real-time stats, sector data, and performance insights, streamed directly to each racer during the race. The technology includes projection mapping and elements such as power-ups and missiles which are displayed on the screen of the go-kart. For viewers, TV screens show what’s happening in real time. Kart Klash is $30 for members and $40 for non-members with designated race sessions where juniors, teens and adults can compete together. Live leaderboards and detailed performance tracking are available for participants and spectators. Kart Klash is launching at RPM Raceway’s Stamford, CT and Long Island, NY locations, with other locations to follow. Source: RPM Raceway Previous Facebook LinkedIn Copy link Next

The Gröna Lund Amusement Park recently inaugurated some new rides, including a refurbished “Blå Tåget” ride. Stockholm, Sweden Amusement Park Features Synchronized AV System The Gröna Lund Amusement Park recently inaugurated some new rides, including a refurbished “Blå Tåget” ride. Kreativ Teknik Theme Parks Jun 4, 2025 The “Blå Tåget” ride went through a total makeover. This ride is a ghost train loaded with new chills, thrills, and effects especially designed for visitors’ enjoyment. The train passes through several chambers, each filled with skeletons, scarecrows, rats, wolves, fire, lightning, ghosts, and more. The setting inside the ride was designed by artist Magnus Sörman and the entrance to the ride was designed by artist Joakim Hansén. For the technical portions of the adventure-ride, Kreativ Teknik was contacted by Gröna Lund. Kreativ Teknik, a Swedish-based company that mainly works with lighting, control systems, and effects, selected Medialon to be part of the project. Kreativ Teknik delivered a total solution including lighting, smoke, video projectors, control system, as well as the programming of the entire ride’s special effects. One Medialon Showmaster Pro embedded show controller controls and synchronizes the entire AV system. Medialon controls everything from light and sound to lightning, smoke-effects, movements of the animatronics, and video, which are continuously timed and trigged by the exact positions of the train’s chariots. “It was surprisingly quick and easy to set the timings of the animatronics together with the effects. I really liked the system and I want to continue to work with it in my future projects” says Marcus Persson, Project Manager and CEO at Kreativ Teknik. “We think that the project has been carried out really well and it’s been done with great interest and commitment,” Peter Osbeck, Ride Manager at Gröna Lund said.

With Heron AM, composite components featuring intricate geometries and highly customized designs can be produced directly from the digital model, bypassing the manual lamination phase. This significantly reduces prototyping and production times, enabling rapid iterations and design optimizations. Moreover, the process only requires finishing operations such as gel coat application, further cutting down on labor-intensive steps. Heron AM also allows for the use of lightweight yet strong materials, improving component performance while reducing material waste, making the process more sustainable than traditional methods. Its flexibility allows for small-batch or fully customized production, catering to the specific needs of each project. Additive manufacturing benefits The adoption of Large-Format Additive Manufacturing (LFAM) for the production of air grilles on the Pershing GTX116 yacht has led to remarkable improvements in efficiency, sustainability, and overall product quality. By leveraging Caracol’s Heron 300 system, equipped with a high accuracy extruder and a 3-mm nozzle, the grilles were printed using ASA reinforced with 20% glass fiber—a material chosen for its durability and resistance to harsh marine environments. The entire 3D printing process took only 72 hours to complete, producing an air grille measuring 4200 x 400 x 400 mm and weighing 40 kg. Compared to traditional manufacturing methods, this approach has resulted in substantial reductions in lead time (50%), material waste (60%), and overall weight (15%), making it a more sustainable and cost-effective solution. To ensure both weather resistance and a flawless aesthetic, the grille was finished with a gel coat, enhancing its durability against environmental exposure. The implementation of additive manufacturing for such large-scale yacht components showcases the potential of this technology to revolutionize production, offering greater flexibility and performance while significantly cutting down on inefficiencies. The adoption of LFAM has proven to be a key strategy for the marine industry, enabling the production of highly complex and tailored components, optimizing manufacturing processes, and reducing time-to-market. In this context, Caracol’s Heron AM technology emerges as a cutting-edge solution, capable of delivering excellent performance and greater versatility than traditional methods.
