ABSTRACT:
An electronic circuit adapted to receive conditioned force signals from a three-axes load cell mounted on the arm of a robot and provide a stop signal for use by a controller of the robot. The circuit compares the sum of the absolute value of the forces with a variable reference signal. A force trip relay and a masking relay are connected in parallel to provide the stop signal when both the resulting sum is greater in value than the reference signal and the robot is in an operating condition in which high forces do not normally occur.
