Servo assembly, robot joint and robot
A servo includes a casing, a motor assembly arranged within the casing and including a hollow output shaft, a harmonic drive including a flex spline, a wave generator arranged and a circular spline that comprises, a first bearing to rotatably connect the flex spline to the circular spline so as to enable one of the flex spline and the circular spline to serve as an output member, and enable the other one to serve as a fixed member, a post fixed to the output member and received in the output shaft, a first source member arranged at one end of the post that is away from the output member; and a control circuit board having a first sensing member. The first sensing member and the first source member corporately constitute a rotation sensor to detect rotation of the output member.
