ABB of Västerås, Sweden, is a pioneer among world industrial robot manufacturers when it comes to using laser-based measuring technology to ensure robot precision. ABB, with an installed base of 125,000 robots, stands out as the world’s largest in the arena of industrial automation. And Leica Geosystems’ equipment is instrumental in a unique calibration method that offers customers exact robot positioning accuracy throughout the entire life cycle of their robots.

Absolute Accuracy in a Nutshell
Absolute Accuracy is a process that ensures that a robot will retain its accuracy throughout its entire life cycle. The method bridges the gap between the CAD system’s virtual robot’s precision and the work done by the actual robot on the factory floor. Using a laser tracker; a compensation parameter is established that corrects the positioning and the robot’s movements. These parameters take into account both the mechanical imperfections in the pattern of movements and the bending downwards caused by the loads.
