END EFFECTOR BUMP DETECTOR

Abstract:

A system and method is described for detecting abnormal contacts and misalignment of end effector of a robot arm during robotic arm operation. A contact shock transients sensing unit detects signals on the robot arm and generates alarms, identifies the location of the contact shock transients in the robot arm operation, and controls robot arm operation to prevent further damage to the robot arm and articles handled by the robot arm.
