Abstract
In order to develop a robot for colonoscopy, which can provide the same functions as conventional colonoscope, but much less pain and discomfort for patient, a snake-like robot with continuum structure is proposed. The mechanical structure of snake-like robot for colonoscopy is introduced and the angle of single section is calculated. The mechanical model of cantilever beam is built, the force diagram is drawn and the mechanical analysis of single section in bending process is mainly analyzed. Finally, ‘Pro/E’ is used to build model and simulate the process that the snake-like body goes through the colon. This paper lays foundation for the research on snake-like robot for colonoscopy.
