At the Osaka-Kansai Expo (Duration: April 13 – October 13, 2025), a spatial art installation featuring 450 synchronized spheres and light will be exhibited at the Kansai Pavilion, Shiga Prefecture booth. This installation, titled Kinetic Light Vision, is a light art system planned by Lucent Design Co., Ltd.
Our company's EtherCAT-compatible closed-loop stepper motors have been adopted for use in the Kinetic Light Vision system.

Kinetic Light Vision (KLV):
A unique spatial expression system developed by LUCENT, in which translucent acrylic spheres are suspended with ultra-fine wires and illuminated individually with specialized lighting. The spheres are moved vertically with extremely smooth motor control, creating the illusion that they are floating in space.
A proprietary full-color lighting system with an ultra-narrow beam angle of just 0.2 degrees has been specially developed. This world-first spatial system combines delicate motion and richly colored light spheres to create an immersive visual experience.
(Patent pending)

Story Behind the Project
It all began when Lucent Design Co., Ltd. contacted us through our website with an inquiry about motors.
Upon conducting a thorough consultation, we discovered that the project involved several technical challenges: controlling several hundred axes beyond the capabilities of general-purpose controllers, advanced motion control, strict power supply limitations at the venue, a need for compact and simplified wiring, and all within a constrained budget.
We started by proposing the use of EtherCAT for its capabilities in multi-axis control and minimal wiring. Based on this requirement, we considered a system composed of compact motors and controllers compatible with EtherCAT. We selected the FASTECH closed-loop stepper motors—distributed by our company—paired with a PC-based real-time OS architecture.
For the control software, we turned to Micronet Co., Ltd., known for their expertise in EtherCAT and developers of the real-time OS INtime. We requested their assistance in creating a control system that could meet the project's stringent demands.
Our company was responsible for coordinating the overall system architecture, selecting suitable motors, providing experimental setups, proposing a mechanism to reduce wire oscillation, and developing control methods compatible with limited power capacity. Together, we worked toward building a truly unprecedented system.
Thanks to the collaboration of all involved parties, we succeeded in realizing Kinetic Light Vision—a breathtaking spatial art installation where 450 spheres move in sync with light.

System Overview & Technical Highlights
・Compact Wiring & Space-Saving Design
We adopted FASTECH's Ezi-SERVO II-EC-ALL-42M-A-BK-R closed-loop stepper motors.
These integrated units combine an EtherCAT interface, driver, and motor, drastically simplifying the physical wiring.
Control signals are transmitted via EtherCAT fieldbus, with all 450 axes connected through a single daisy-chained LAN cable.
・Motion Control
The control system was developed by Micronet Co., Ltd.
Although the controller provided relatively low-speed (250 Kbps), low-resolution (256-level) position data with a refresh rate of 44 Hz, this data was processed and refined by a smoothing software on a PC.
The refined data was then transmitted to each motor at high speed (4 ms cycle) using the real-time OS INtime, achieving ultra-smooth motion with minimal velocity ripple, complete freedom of movement, and perfectly synchronized control across 450 axes.
We warmly invite you to experience the stunning, vividly colored world of Kinetic Light Vision at the Shiga Prefecture booth, Kansai Pavilion, during the Osaka-Kansai Expo (April 13 – October 13, 2025).
