Fault Tolerant Control in Shape-Changing Internal Robots [PDF]
2020 IEEE International Conference on Robotics and Automation (ICRA), 2020 It is known that the interior of the human body is one of the most adverse environments for a foreign body, such as an in-vivo robot, and vice-versa. As robots operating in-vivo are increasingly recognized for their capabilities and potential for improved therapies, it is important to ensure their safety, especially for long term treatments when little
