Inverse kinematic control of a shape memory alloy actuated smart needle for percutaneous intervention (original) (raw)

TENCON 2017 - 2017 IEEE Region 10 Conference, 2017

Abstract

This paper presents the development and control of a novel active needle for percutaneous intervention. Using vision feedback of the actual tip of the needle, inverse kinematics based closed loop control in tracking a 3D curved path is performed. Shape Memory Alloy (SMA) wires are deployed as actuators for the developed active needle system. In-air experiments are performed to evaluate and validate the inverse kinematic closed loop control performance of the needle in 3D curvilinear path tracking. The results obtained are acceptable within clinical limits.
