A robot arm for industrial robots comprises one or several jointed arms ( 1,1 c) that are mutually connected to each other by means of rotary joints ( 1 a, 1 b), and a jointed arm ( 1 ) connected to a base ( 3 ), in which an angle transducer is arranged in the rotary joints ( 1 a, 1 b) in order to measure exactly the angular relationship between the jointed arms ( 1,1 c) or between the jointed arm ( 1 ) and the base ( 3 ), in order to make possible adjustment of the robot arm into the desired angular position.
