Abstract
The diagnostic application of magnetic control capsules in medical treatment is progressively increasing. At present, the accurate dynamic control of the capsule robot is becoming more and more important. There is a significant aim to establish a friction model of the tethered capsule robot, and the friction model can be applied to simulate the drag force of the tethered and all friction between the capsule and the environment. We confirmed the fifth-order linear fitting relationship between the friction factor of the friction model and the speed of the external permanent magnet. With the learned friction model, effective speed ranges of three mediums are obtained on PVC, paper, and polyester-cloth. In the article, a tethered capsule robot system driven by a robot manipulator is built, and a plane motion method to learn the friction model is proposed.
