Error Modelling for Master Slave Surgical Robot System

Abstract

The Position and orientation accuracy of robot manipulator has long become a major issue to be considered in its advanced application. A linear error model that described the end-effector position and orientation errors of the master salve surgical robot system due to kinematics parameters errors has been presented. A computer program to perform the accuracy analysis has been developed in MATLAB. This methodology and software are applied to the accuracy analysis of a master-slave surgical robot system. The position error in its workspace cross section (XOZ) has been plotted as 3D surface graph and discussed.
