APPARATUS AND METHOD FOR ROBOTS TRACKING APPOINTED PATH WITH HIGH PRECISION

Document Type and Number:

WIPO Patent Application WO/2010/003289

Kind Code:

A1

Abstract:

An apparatus and a method for robots tracking appointed path with high precision are introduced. The process is divided into three phases. The welding line position measure information and coaxing vision measure information are used in the former two phases to compute the welding line position forehand and the deviation between the tool center of the robot and the welding line, and the compensation data of the track deviation of the tool center of the robot and the reference data of the welding line are obtained. The track and compensation is achieved by the welding line position measure information and the reference data of the welding line in the practical welding phase. The tool center of the robot is made to go ahead continuously along the appointed path according to the movement of the robot system corrected by the position correction apparatus.
