Electric robot joint actuators are replacing hydraulic systems in humanoid robots with higher efficiency, compact integration, precise control, and scalable motion solutions.

Compare Harmonic Rotary Actuator, Direct Drive Rotary Actuator and Hollow Rotary Table for automation. Learn the differences in torque, speed, precision, integration and applications.

According to statistics released by the EtherCAT Technology Group (ETG) in 2024, EtherCAT has captured 39.2% of the global industrial robot communication protocol market, with an annual growth rate of 12.7%, significantly outperforming other competing protocols. Its advantages are particularly evident in key application scenarios: from multi-joint real-time coordinated control in humanoid robots, to multi-sensor fusion in autonomous driving, and human–machine collaboration in Industry 4.0. EtherCAT is redefining how intelligent systems interact with the physical world.

The TCHL Harmonic Joint Module is a harmonic joint module that integrates a torque sensor directly into the harmonic drive reducer. The torque sensor enables precise measurement of the drive system’s operating status and required torque values, allowing accurate load detection of the actuator. This helps prevent overload and enables safer human–robot interaction. The module features fully integrated cables and connectors, allowing fast, precise component connections and enabling safe, responsive motion control through a highly integrated design.
