Intelligent control of redundant manipulators in an environment with obstacle

Abstract

A neural optimization network is proposed to control redundant robot manipulators in an environment with obstacles. The weightings of the network are adjusted by considering both the joint dexterity and the capability of collision avoidance of joint differential motion. The fuzzy rules are proposed to determine the capability of collision avoidance of each joint. To show the validities of the proposed method, computer simulation results are illustrated for a 3-d.o.f planar redundant robot.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
