ABSTRACT:
In a robot, the transmission of electrical power and signals is effected without contact at a joint position, either by using a magnetic coupling provided by means of a transformer formed by windings housed in ferrite cores, or by capacitive coupling obtained by means of two capacitors formed by annular surfaces facing each other, the two cores or the two plates being at a predetermined spacing so that one part of the robot is able to turn by more than 360.degree. around an axis relative to another part without any limit on rotation.
