Abstract: The robotic work object cell calibration system includes a calibration device that emits a pair of beam-projecting lasers acting as a crosshair, intersecting at a tool contact point. The calibration device also emits four plane-projecting lasers, which are used to adjust the yaw, pitch, and roll of the robot tool relative to the tool contact point. Initially, the calibration device is placed in a selected position on a fixture or work piece on the shop floor. The robotic work object cell calibration method increases the accuracy of the off-line programming and decreases robot teaching time. The robotic work object cell calibration system and method are simpler, involve a lower investment cost, entail lower operating costs than the prior art, and can be used for different robot tools on a shop floor without having to perform a recalibration for each robot tool.
