End-effector path planning and collision avoidance for robot-assisted surgery
International Journal of Precision Engineering and Manufacturing(2016)
摘要
The limited workspace and potential for collision between the robot arm and surrounding environment are challenges in robotassisted surgery. In robot-assisted surgical procedures, the surgical robot’s end-effector must reach the patient’s anatomical targets without collision with the patient or surrounding instrument. This paper proposes a novel end-effector path planning method for a robot-assisted surgical system. A collision detection and avoidance method was also developed to create a collision-free path to enhance patient safety. The proposed algorithm also addresses how to update the planned path when the patient moves during a surgical procedure. Experimental results showed that the proposed method successfully solves the path planning and collision avoidance problem in robot-guided surgery.
