Human Robot Harmonic Joint Module with Torque Sensor and Integrated Cable Connector

●  Introduction

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.

Harmonic joint modules with multiple connection options

Designer Speaking 

Primarily developed for users in the field of embodied intelligence, this system features comprehensive mounting interfaces while significantly reducing joint volume and weight, allowing users to systematically reduce the weight and manufacturing complexity of connecting components.  Furthermore, it integrates an output torque sensor without increasing the weight or volume of the joint, enabling the robot to achieve higher dynamic response performance, superior data acquisition quality, and greater load-carrying capacity.
