The Cartek Robotics advanced wheel alignment system,initially designed for car manufacturers has been redesigned for any service center where accuracy and repeatability is a must. This system doesn't use rim clamps or wheel unit sensors, but employs two robots that glide back and forth on either side of the vehicle to automatically perform wheel alignments. The robots find the vehicle and its position on the alignment rack, detecting different diameter wheel sizes, and obtaining alignment readings in less than 70 seconds. It lightly touches tires to record alignment angles. Made in the U.S.A.
