Product Introduction
The linear joint module is specifically designed for humanoid robots, employing a high force-to-weight ratio motor and planetary roller screw integration solution to achieve efficient linear drive and precise position control. It features high rigidity, low backlash, and built-in force and position sensing capabilities, meeting the demands of high-load movements such as jumping and squatting. The module's compact structure supports high dynamic response and low-energy operation, making it a key actuator for constructing the lower limbs and core drive system of high-performance humanoid robots.
