A stable visual servo controller for camera-in-hand robotic systems

Abstract

In this paper we present a new visual servo controller for camera-in-hand robotic systems. We provide a Lyapunov stability analysis including the full nonlinear robot dynamics into the overall closed-loop system. Besides the closed-loop stability property, the control system obviates the use of the inverse kinematics and inverse Jacobian. Experiments on a two degrees of freedom robot manipulator are presented to illustrate the controller performance.
