Abstract
This study presents a solution for the inverse kinematics problem in serial 6R manipulator. Using only seven equations—composed of Duffy’s four kinematical equations containing three angles and three corresponding angles’ identical equations—instead of the traditional 14 equations, the authors reduced the inverse kinematics problem in the general 6R manipulator to a univariate polynomial with a minimum degree based on the Groebner Base method. From that, they concluded that the maximum number of the solutions is 16, generally. Also, the mathematics mechanization method can be extended to solve other mechanism problems involving nonlinear equations symbolically.
