Calibration of robot kinematics using a double ball-bar with embedded sensing
Today’s industrial robots are highly repeatable, but need to be calibrated to improve their absolute accuracy. This calibration can be done on many of the robot properties such as kinematic parameters, joint friction or bending stiffness. This thesis explores a calibration procedure for the kinematic parameters, that use a specialized piece of hardware - the double ball-bar. The double ball-bar re
