The MAX IV synchrotron laboratory in Lund, Sweden had a difficult challenge. They needed to catch X-rays coming from a high-energy atomic collision with an extremely expensive and very small sensor. For each new experiement, while they could theoretically determine the direction of the X-ray, they needed a flexible device to position the sensor in exactly the calculated position and orientation. Using Max IV Lab’s Kuka robot as the start, Cognibotics used its deep knowledge on robot calibration, robot elasticity, and patented measurement technology to provide high performance absolute accuracy positioning cabability for the Kuka. The accuracty result was beyond what was normally provided by the Absolute Accuracy option for the Kuka robot. With the Cognibotics software, the Max IV Lab Kuka robot accurately catches X-rays, even in the dark.
