Position Control of Continuum Manipulator with Twin-Pivot Compliant Joints

Abstract

This paper proposes a novel closed-loop PD controller based on kinematic for continuum manipulator with twin-pivot compliant joints. The purpose of the twin-pivot compliant joints is to decrease the twisting angle caused by gravity of manipulator and payload. We build the forward and inverse kinematic to control the end-effector of continuum manipulator with twin-pivot compliant joints. In this paper, first we build forward and inverse kinematic of continuum manipulator with twin-pivot compliant joints. We then build the controller based on kinematic models for a continuum manipulator with 24 Degrees of Freedom (DoF). Finally, simulation studies are carried out to test the proposed approach.
