Rotary module for robots BSJ series

Product description
Featuring hollow wiring and a highly integrated drive-control module, this design deeply integrates drive, transmission, and sensing modules. Through built-in torque closed-loop control and full-state feedback within the servo, it achieves a bionic balance of "force control precision + dynamic response" to meet humanoid robots' dual demands for both strength and performance.
