What is the key advantage of using a laser tracker for robot calibration compared to traditional methods?

The key advantage of using a laser tracker for robot calibration compared to traditional methods is its ability to accurately measure the robot's position and orientation in 3D space over a large working volume. Traditional methods, such as using dial indicators, gauge blocks, or coordinate measuring machines (CMMs), often have limitations in terms of measurement range and accuracy, especially when dealing with large robots or complex robot cells. A laser tracker uses a l....
