Compact Variable Stiffness Actuator for Surgical Robots
Journal of Robotics and Mechatronics, 2022 Highly rigid surgical robots are capable of precise positioning; however, there is a risk of injury to the surrounding organs owing to undesired contact. To solve this problem, surgeons can change their stiffness according to the desired motion by contracting and relaxing the muscles. Therefore, surgical robots that can change their stiffness according
