Robstride joint motors

Integrated joint motors from a Chinese vendor that pack a brushless motor, gearbox and driver into one cylinder speaking CAN FD. LeRobot Humanoid uses them in its lower body, which is a large part of how that machine reached USD 2,500: the money goes into motors rather than custom joint modules.
