Abstract
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. This makes the robot joint more compact with a larger rotation range and a long lifetime in a cost effective way.
