Abstract

A robot having a low-inertia manually actuated arm that functions as a teaching arm for a symmetrically similar powered operating arm disposed on the robot symmetrical thereto. The teaching arm is provided with compensating devices continuously balancing the combination of the teaching arm and a tool removably mounted thereon so that gravitational forces are continuously compensated. The teaching arm is in a state of continual equilibrium so that the tool thereon can be moved manually accurately and smoothly and substantially inertia-free. The teaching arm accordingly functions as a light-weight highly accurate programmer for the powered operating arm of the robot.
