A Study on Anchoring Ability of Three-Leg Micro Intestinal Robot

Abstract

This paper proposes an anchoring and extending micro intestinal robot for medical inspection and surgery propose. The three-leg anchoring method is discussed in detail, and micro robot phantom model is used to test anchoring related parameters for mechanical design. A prototype is designed and fabricated base on the experiment results and is tested in in-vitro experiment. The prototype is locomotive in a pig small intestine under a diameter limitation.
