Experiences on the Design of a Needle Insertion Surgery Robot: Kinematic Analysis

Abstract

In this work is presented the evolution of the concept of a needle insertion surgery robot. Five different prototypes were proposed, keeping the core concept of decoupling kinematics, and passing from a passive device to an autonomous robot. The kinematics of the mechanisms are presented. The different configurations for the inverse kinematics are introduced. The workspace of the final prototype is analyzed.
