A distributed approach for solving the position inverse kinematics of mobile parallel manipulators

摘要

This paper presents a modified method for solving the Inverse Kinematics problem for Parallel Manipulators. The manipulator assumed consists of two 6R serial chains in parallel (biped configuration) with multiple orthogonally intersecting joint axes. The problem question is to determine whether or not is it possible to attain a certain goal configuration of the base and if yes then how to solve for the unknown joint angles. In principle this method can be extended to applications for mobile parallel manipulators with more than 2 serial chains.
