Abstract: A method based on algebraic and identity conditions for mechanism is presented to solve artificial upper limbs inverse kinematics problems. The method can avoid multi-times inverse matrics mutiplication in the course of deduction. The spatial positions of each joint angel are shown in CATIA by secondary development of CATIA with VB. It can determine the solutions directly and lay the foundation for movement research of artificial upper limbs.

Key words: computer application, artificial upper limbs, visualization, secondary development of CATIA, inverse kinematics resolution
