Elasto-kinematic modelling and calibration of industrial manipulators with coupled wrist gearboxes
This thesis examines how elastic deformations affect the kinematics and stationary positional and orientational accuracy of an industrial manipulator. The analyzed robot had a wrist design which introduced a coupling between the two wrist joints, i.e., the outermost two joints responsible for orienting the end-effector. This meant that one of the wrist motors had an effect on both joints, and that
