摘要: Various actuators have been studied to develop micro robots for a capsule endoscope. In particular, some locomotive mechanisms based on the SMA (Shape Memory Alloy) actuator, PZT Polymer and motor actively fabricate microrobot Before we microrobots, smart material-based such as SMA, PZT, Polymer, are evaluated from viewpoint of power consumption, response time, generative force. Based evaluation results, microrobots developed properly diagnose digestive organ. The earthworm-like robot is fabricated tested in colon swine order demonstrate performance locomotion. However, actuator-based does not supply enough driving force locomote Therefore, paddling-based mechanism constructed diseases small intestine. these research efforts, expect next generation that can human organs.
