Abstract:
1. A robot teach tool, comprising: a body assembly with a proximity sensor mounted therein that is releasably mated with a robot end effector; a foot assembly coupled to the body assembly, wherein the foot assembly comprises a sensor target mounted therein that is located about the proximity sensor; and wherein the proximity sensor and the sensor target are configured to detect signals representative of a perturbation as the robot end effector moves the body assembly and foot assembly from a central position within a workpiece receptacle through six degrees of freedom, wherein the signals are used to determine a precise orientation for the robot end effector to pick up and place a workpiece to and from the workpiece receptacle, wherein the signals representative of the perturbation are generated in response to the foot assembly colliding with a horizontal surface or a vertical surface of the workpiece receptacle.
