摘要: A substrate transport apparatus includes a transport chamber, a drive section, a robot arm, an imaging system with a camera mounted through a mounting interface of the drive section in a predetermined location with respect to the transport chamber and disposed to image part of the arm, and a controller connected to the imaging system and configured to image, with the camera, the arm moving to or in the predetermined location, the controller effecting capture of a first image of the arm on registry of the arm proximate to or in the predetermined location, the controller is configured to calculate a positional variance of the arm from comparison of the first image with a calibration image of the arm, and determine a motion compensation factor changing an extended position of the arm. Each camera effecting capture of the first image is disposed inside the perimeter of the mounting interface.
