Apparatus for detecting distortion of transfer arm robot An apparatus for detecting distortion of a transfer arm robot comprising at least an electromagnetic radiation source and at least a sensor for detecting said electromagnetic radiation. The source and sensor may be mounted on a reference plane parallel to the plane of the arm at which portion distortion is to be detected wherein the radiation is reflected off said portion of the arm. The sensor may be mounted at an appropriate distance from the source to receive the radiation reflected by said portion of arm at a normal and distortion-free state. When the sensor is out-of-range to receive radiation reflected by said portion of arm at a distorted state, signal may be generated to alert or halt the operation of the transfer arm or equipment as a whole.
