Microsecond‑Level Synchronous Control Patent Granted

We are excited to announce that our patent for "Low‑latency RF‑based heterogeneous multi‑agent microsecond‑level synchronous control system" has been officially granted in April 2026. This achievement marks a significant milestone in robot collaborative control technology and demonstrates YJ‑Tek's international advanced level in this critical field.

The patented technology enables microsecond‑level synchronization for heterogeneous multi‑agent systems, with latency under 1μs. This breakthrough addresses one of the most challenging aspects of humanoid robot development: precise coordination of multiple joints (such as bipedal legs and dual arms) to ensure smooth, stable, and natural motion.

Technical Innovation

Our synchronous control system uses low‑latency radio frequency (RF) communication to achieve time synchronization across distributed controllers, sensors, and actuators. Unlike traditional methods that rely on centralized timing, our distributed approach reduces single‑point failure risks and scales efficiently with the number of robot joints or multi‑robot clusters.

Key innovations include:

• Adaptive clock synchronization algorithm that compensates for transmission delays and clock drift
• Redundant communication paths to ensure robustness in electrically noisy environments
• Support for heterogeneous agents (different processors, communication protocols, and sensor types)
• Seamless integration with our existing IMU, force/torque sensors, and joint modules

Applications in Humanoid Robots

This technology is already being deployed in several humanoid robot platforms across industrial, medical, and service sectors. In industrial settings, it enables precise assembly and handling tasks requiring sub‑millisecond coordination between arms and end‑effectors. In medical rehabilitation robots, it ensures safe and natural‑feeling interaction with patients.

The patent is part of our broader portfolio of 17 patents covering synchronous control, inertial measurement, wireless communication, sensor fusion, and intelligent formation. Together, these technologies form the foundation of our "Patent‑Product‑Scenario" tripartite R&D model, ensuring that our innovations are not only scientifically advanced but also commercially viable and practically applicable.

Future Developments

We are currently integrating this synchronous control technology into our next‑generation YJ‑Controller C‑Series, which will support up to 64‑axis real‑time control. We are also collaborating with several leading humanoid robot OEMs and research institutes to further refine the technology for specific application scenarios, including outdoor navigation, human‑robot collaboration, and swarm robotics.
