Abstract
A method, system and test fixture for allowing testing and calibration of various operation parameters of an overhead traveling vehicle (hereinafter 'OTV') are disclosed. The invention implements a test fixture that includes a rotatable bearing set for rotatably engaging a wheel of the OTV such that the wheel can rotate but the OTV remains stationary. The bearing set is held in a raised position, similar to the operational position of the OTV, by a raised support. The test fixture may also include a reflective tape for use with an optical sensor(s) of the OTV. In this fashion, operation parameters of the OTV such as drive servomotor velocity, current gain, current offset, OTV travel profile, optical sensor op-amp gain, etc., can be tested and calibrated.
