System for determining manipulator coordinates

摘要

An inverse kinematics method of determining joint variables for a manipulator is obtained by forming a model by modifying offset values of a selected arm segments of the manipulator to define a model for which it is possible to derive closed-form inverse kinematics equations for solving the joint variables for said model, developing from said closed-form inverse kinematics equations a system of not more than 3 non-linear equations in not more than 3 unknowns which when solved give an inverse kinematics solution for the model, solving the system of at most 3 non-linear equations to provide the inverse kinematic solution for said manipulator to determine its joint variables.
