Patent number: 10632630Abstract: A robot joint and a robot using the robot joint is provided. The robot joint includes a first part and a second part configured to be rotatable with each other around a joint axis. A flexible printed circuit board is further included with a first fixing point and a second fixing point respectively fastened to the first part and the second part. The flexible printed circuit board is spiral-shaped prior to bending. With the relative rotation of the first part and the second part, the flexible printed circuit board is bent at various bending portions.
