Accuracy and Repeatability of a Parallel Robot for Personalised Minimally Invasive Surgery
摘要
The paper presents the methodology used for accuracy and repeatability measurements of the experimental model of a parallel robot developed for surgical applications. The experimental setup uses a motion tracking system (for accuracy) and a high precision measuring arm for position (for repeatability). The accuracy was obtained by comparing the trajectory data from the experimental measurement with a baseline trajectory defined with the kinematic models of the parallel robotic system. The repeatability was experimentally determined by moving (repeatedly) the robot platform in predefined points.
