Abstract: A dual-output-shaft servo includes a housing including two first sensors and two actuating mechanisms. Each actuating mechanism includes a motor assembly, a speed reduction mechanism opposite the motor assembly, and a transmission mechanism arranged between the motor assembly and the speed reduction mechanism. The speed reduction mechanism includes an output component, and a connection shaft is fixed to the output component. A first sensor counterpart is attached to an end of the connection shaft which faces the motor assembly. The transmission mechanism is to transmit mechanical power from the motor assembly to the speed reduction mechanism. The axes of rotation of the output components of the speed reduction mechanisms are skew or intersected with each other.

Abstract: A robot joint includes a casing, a motor assembly including a stator and a rotor that are arranged within the casing, and a harmonic drive received, at least in part, in the rotor. The harmonic drive includes a circular spline, a wave generator fixed to the rotor, and a flex spline. The circular spline is arranged around and engaged with the flex spline. The wave generator is received in the flex spline and configured to drive the flex spline to rotate with respect to the circular spline. The robot joint further includes an output shaft fixed to the flex spline.
