The production of a robot joint motor integrates multiple advanced technologies, including electric motor design, precision reduction systems, encoder technology, servo control, torque sensing, mechanical structure design, communication protocol development, and reliability testing. As a result, the technical barrier for developing a high-performance robot joint actuator is significantly higher than that of a conventional servo motor or standalone gearbox. This article introduces several companies that have entered the market with commercially available robot joint motors and integrated joint actuator solutions.
