Laser Guidance For Windshield Assembly Robot
Hummer chassis on the assembly line were not uniformly aligned as they entered the automated windshield installation work cell. In order for the robot to successfully perform its task, a unique coordinate registration on the windshield frame was required for each vehicle.
Newton engineers employed laser profilometry (the measurement and profiling of a 3D object) to track each Hummer chassis and guide the windshield installing robot. They developed a system using four lasers and cameras to provide individualized distance, rotation and angle data to the PLC as each vehicle moved through the work cell.
