The TX90 measuring robot from Stäubli Robotics
The task of measuring is handled by the Stäubli TX90L robot. A stationary laser tracking system is used to achieve the level of absolute precision required. In conjunction with the exemplary real-time control of the robot and a multi-axis force/ torque sensor, it is possible to position the six-axis robot within a range of a few micrometers and reliably maintain the margin of measurement uncertainty to less than 100 micrometers throughout the process. While the robot’s kinematics are controlled with near-micrometer accuracy by the laser tracker, its precision and motion control also play key roles. Ultimately, the mechanics of the robot must be capable of transforming the most intricate of commands from the laser tracker for precise mechanical positioning into micro-movements.
Here, Stäubli’s own JCM drive technology, in which the engine and gears constitute a single unit, has proven to be extremely accurate. It requires only very short control intervals before the robot reaches its measurement positions. This results in quick, reliable measuring.
