The paper presents an application of Interval Newton method to solve the inverse kinematics and redundancy resolution of a serial redundant manipulator.Such inverse problems are often encountered when the manipulator link lengths, joint angles and end-effector uncertainty bounds are given, which occurs due to because of inaccuracies in joint angle measurements, manufacturing tolerances, link geometries approximations, etc.The inverse kinematics of three degree of freedom planar redundant positioning manipulator without endeffector has been evaluated using the manipulability of Jacobian matrix as performance metric.To solve the nonlinear equation of inverse kinematics, the multidimensional Newton method is used.The inverse kinematics is intended to produce solutions for joint variables in interval of tolerances for specified end effector accuracy range.As exemplar problem solving, a planar 3-degrees-of-freedom serial link redundant manipulators is considered.
