Slip sensor, for workpiece in robot gripper, has light source to provide reflection image onto sensor with predetermined threshold

摘要

The workpiece slip sensor for a robotic gripper has a light source directed to produce a reflection on the workpiece. The reflection is picked up by a sensor head which determines the image produced and compares it to a threshold value to determine if slippage has occurred. The sensor compares its position to the position of the workpiece reflection. The robotic gripper can be a linear gripper.
