Design and Kinematic Analysis of a New End-Effector for a Robotic Needle Insertion-Type Intervention System

International Journal of Advanced Robotic Systems, 2014
This paper presents a new end-effector as a key component for a robotic needle insertion-type intervention system and its kinematic analysis. The mechanism is designed as a spherical mechanism with a revolute joint and a curved sliding joint, and its ...

Characterization and control of self-motions in redundant manipulators [PDF]

The presence of redundant degrees of freedom in a manipulator structure leads to a physical phenomenon known as a self-motion, which is a continuous motion of the manipulator joints that leaves the end-effector motionless. In the first part of the paper,
