Calibration of parallel kinematic machine tools using mobility

In the application of parallel kinematic machine tools (PKM), because of errors in the geometric parameters, it is necessary to calibrate the PKM to improve the positioning accuracy. In existing self-calibration methods, either some redundant sensors on passive joints or some mobility constraints on the kinematic chains are used. However, the mobility constraints …

Parallel robots [1], [2], [3] are closed-loop kinematic manipulators usually with two platforms (a base and an upper platform as the end-effector) that are linked by several kinematic chains. Each kinematic chain has joints that are either actuated (active joints generating the motions) or not (passive joints). The consecutive joints are linked by a body.
