摘要
为了提高肠道疾病主动诊断能力,研究了基于摩擦力控制的结肠微型机器人.摩擦力模型分析了肠道摩擦力控制因素,并利用实验模板和黏附制剂在体外肠道开展的摩擦力实验,验证了接触纹路和接触黏度对肠道摩擦力的影响.摩擦接触装置的研制综合考虑了肠道应用环境和摩擦力控制因素,最终装配在内窥镜机器人样机上实现了摩擦控制运动.实验结果表明:基于摩擦力控制内窥镜机器人样机能够适应不同的运动环境而实现有效的主动运动,且运动环境会对其运动速度产生不同影响.
To improve the diagnosis ability of intestinal diseases, a colonic micro-robot was proposed, based on friction control. The friction model analyzed the factors of the intestinal friction control. Under the use of custom-built templates and adhesive polymers, some experiments on the in vitro intestinal surface inves- tigated the influences of contact pattern and contact viscosity. Considering the frictional factors and the ap- plied environment, a friction contact device was designed for the endoscopic robot to realize the frictional locomotion. The experimental results show that the robotic prototype can adapt the serious environments to realize the active locomotion, and the locomotion environments may also produce different influences on its active locomotion speed.
