Patent number: 11648068Abstract: A magnetic robot system is provided. The magnetic robot system comprises: a catheter having a first magnet coupling part provided at the front end thereof; and a mobile robot having a second magnet coupling part provided at the rear end thereof, and having a driving magnet, wherein the mobile robot is coupled to the catheter by means of magnetic force between the first magnet coupling part and the second magnet coupling part, and the magnetic force coupling of the first magnet coupling part and the second magnet coupling part can be released by rotating magnetic torque generated by the driving magnet because of the application of external rotating magnetic force.Type: GrantFiled: April 3, 2018Date of Patent: May 16, 2023Assignee: IUCF-HYU (INDUSTRY-UNIVERSITY COOPERATION FOUNDATION HANYANG UNIVERSITY)Inventors: Gunhee Jang, Wonseo Lee, Jae Kwang Nam, Jongyul Kim
