RobStride

A Chinese maker of robot joint actuators whose RS-series integrated joints are common in quadrupeds and small humanoids.

RobStride Dynamics is a Chinese maker of robot joint modules, best known for its RS00–RS06 line of integrated joints: a brushless motor, planetary gearbox, driver, and encoder packed into a single disc-shaped module that takes commands over a CAN bus and supports position, velocity, torque, and MIT-mode control, which sends target position, velocity, stiffness, damping, and feedforward torque all at once. These “quasi-direct-drive” joints have a low gear ratio and can be back-driven, which suits reinforcement-learning-based locomotion control that outputs joint targets directly, making them a common power source for quadrupeds, small humanoids, and desktop robot arms. Its core team is reported to come from Xiaomi's CyberGear micro-motor project. No reliable source was found for its founding year or funding, so those are omitted here.
