HONPINE TCHL series harmonic drive joint module is a game-changing product that achieves disruptive improvements in multiple aspects such as lightweight design, integration level, and connection convenience. This article will analyze its revolutionary enhancements with you.

Dual encoder robot joints are becoming increasingly important in high-performance robotics. But adding a second encoder is not simply a matter of installing another sensor. The real purpose is to answer two different questions: How much has the motor moved? and How much has the robot joint actually moved? In a robot joint module consisting of a frameless torque motor, precision reducer, encoder and output flange, the motor-side encoder can accurately measure motor position and speed. However, the actual joint output can still be affected by transmission error, torsional deformation, friction, thermal drift, assembly tolerances and changes in external load. This is why a dual encoder robot joint can provide a more complete feedback architecture. One encoder monitors the motor side, while the other measures the joint output side. Together, they allow the controller to observe both the motor dynamics and the actual joint position.

As embodied AI rapidly evolves from research to real-world deployment, the robotics industry is entering a new era of intelligent automation. While many companies compete in the crowded robot manufacturing market, HONPINE has chosen a different path—building a unified robot joint module platform that serves as the foundation for the next generation of intelligent robots. According to HONPINE Founder, the company's long-term vision is clear: to become the "power heart" and hardware foundation of the robotics era.

The production of a robot joint motor integrates multiple advanced technologies, including electric motor design, precision reduction systems, encoder technology, servo control, torque sensing, mechanical structure design, communication protocol development, and reliability testing. As a result, the technical barrier for developing a high-performance robot joint actuator is significantly higher than that of a conventional servo motor or standalone gearbox. This article introduces several companies that have entered the market with commercially available robot joint motors and integrated joint actuator solutions.
