ABSTRACT:
A robot `teaching head` for attachment to the operating arm (8) of a robot and usable for accurately setting the robot arm to respective ones of a sequence of positions, relative to a workpiece or template while `teaching` the robot to carry out a process involving movement through that sequence. The head comprises a hollow cyclindrical body (1), a sprung slidable sleeve (14) on the body from which there extends a series of attitude setting contact fingers (42) able to make contact with the workpiece and thereby set the attitude of the robot arm, a distance setting contact member (29, 34) for defining a desired distance between the workpiece and robot arm, and a hydraulically driven probe (24, 38) for centering the arm over a desired position on the workpiece. A series of indicator lamps (49) give a visual check of accurate positioning.
