Abstract
By providing a yoke (36) to the shoulder (15) of a robot for inspecting and repairing the tubes of a nuclear boiler, which yoke can receive an expandable anchoring piece (35) of an auxiliary tool (23) connected to the wrist (18) of the robot, said auxiliary tool (23) being provided with additional span fingers (37, 38), it is no longer a time-consuming and therefore expensive procedure to also inspect the tubes that lead to the tube sheet passages (9) into which the usual span fingers (8) of the robot were originally fixed.
