Product Introduction
This planetary joint module is specifically designed for humanoid robot joint actuation, integrating a high-torque-density frameless motor and a precision planetary reducer, featuring high rigidity, zero backlash, and strong overload capacity. The module incorporates dual encoders and a torque sensor, supporting high-precision force and position control and compliant interaction. Its compact and lightweight structure enables smooth, highly dynamic rotational motion, making it widely applicable to core load-bearing joints in robots such as the hip, knee, and shoulder, meeting the complex movement and safe collaborative requirements of humanoid robots.
