Preliminary evaluation of a novel vision-guided hybrid robot system for capsulotomy in cataract surgery☆☆
Displays(2022)
Abstract
•A novel 6-DoF hybrid robot is introduced to improve the stability and compactness of surgery robot.•A robot control algorithm with an RCM constraint is proposed to reduce the position error of the robot.•An edge detection method based on the U-Net is proposed to provide visual feedback to the robot and increase the precision of tracking the edge of the anterior capsule.•Experimental results are presented to indicate that the proposed robot system can increase the performance of cataract surgery.
