Abstract: A robot is disclosed having a plurality of movable links or members interconnected end-to-end in series. Associated with each is an actuator and position transducer. Some of the links are relatively massive and cannot be readily moved without power assistance when the robot is manually programmed, while other links or members, namely those constituting the wrist, are relatively lightweight which permits movement thereof without power assistance during manual programming. A force transducer is connected in series with the output element of the robot in association with one of the massive links located between the wrist and the stationary base on which the robot is mounted. The transducer senses forces during programming applied to the massive links via the wrist when manual programming forces are applied to the robot output. The force transducer provides an output signal for each of the massive links correlated to the component of the manual programming force transmitted thereto via the wrist.
