Product Display

Joint module is a highly integrated mechanical component, which combines motor, reducer, encoder and harmonic reducer to achieve high precision motion control. This integrated design makes the joint module widely used in industrial robots, automation equipment and other fields.

Support SDO TPDO RPDO
In the joint module, the host software using CANopen protocol can effectively manage and monitor the motor state of each joint and modify the related parameters.
Monitor motor running status, speed and torque monitoring, modify motor speed parameters, torque limit modification, position monitoring parameters modification
Size & Interface


Application Cases
The limb movement of the humanoid service robot depends on the joint module. They can be used in hotel reception services, robots through the joint module control arm and body movements, such as guiding guests, delivery and other service behaviors. Its joint module can make the robot's movements more natural and smooth, improving the user experience.
Devices such as exoskeleton robots for limb rehabilitation use joint modules to assist patients in rehabilitation training. The joint module can provide help or resistance depending on the patient's stage of recovery and movement ability. For example, for rehabilitation after knee injury, the knee module of the exoskeleton robot can guide the patient to the correct flexion and extension movement, and at the same time can record the movement data to provide a reference for doctors to adjust the rehabilitation program.
