Abstract:
A calibration system for calibrating a robotics system, wherein the calibration system comprises:a laser detection device that has at least one laser detection surface and wherein the laser detection device is operational to determine a presence of a laser beam on the laser detection surface;a plate that has at least one hole wherein the plate is coupled in parallel to the laser detection device so the laser beam will be present on the laser detection surface if the laser beam passes through the hole in a direction perpendicular to the plate and toward the laser detection surface;a laser projection device that is operational to project the laser beam and that is operational to be coupled to the robotics system; anda control means for directing the robotics system to position the laser projection device at a plurality of calibration positions that project the laser beam toward the plate, for obtaining information from the laser detection device regarding the presence of the laser beam on the laser detection surface when the laser projection device is positioned at the plurality of calibration positions, and for determining a corrective factor for the robotics system based on the calibration positions and the information from the laser detection device.
