AI Technical Summary
Existing harmonic joint modules, when integrating torque sensors, suffer from difficulties in sensor data processing, insufficient accuracy, or structural interference from load bending moments, making it difficult to meet the lightweight, miniaturized, and highly integrated requirements of embodied intelligent robots for torque sensing.
A force-controlled sensing lightweight harmonic joint module is designed. By installing a torque sensing component on the output flange and combining it with a reverse-mounted harmonic reducer, the inner ring of the roller bearing is used as the input support ring surface to directly support the output flange. The sensor installation position and support structure are optimized without increasing structural complexity.
This approach achieves miniaturization and weight reduction of the module, improves the detection accuracy and structural stability of the sensor, simplifies the connection structure of the robotic arm, shortens the axial length of the module, and enhances the overall torque sensing capability.
