Abstract
In this paper, we have reported that design and analysis of an in-liquid micro robot with self-energy harvesting and self-propulsion functions. There are two problems to develop micro robots with 1mm3. Those are a sticky problem and an energy source problem. To investigate solutions of those problems, we look at the natural world and found out microbes are living in liquid. They harvest energy by eating foods and solar energy and move freely in liquid; they have already solved sticky problem and energy source problem. That is our motivation to research and develop micro robot which moves in liquid. In this report, we have proposed new concept of the robot composed of voltaic cell as energy harvester and comb actuator as its source of motion. We have estimated the dynamic motion of the robot by simple linear model. We have also conduct FEM analysis to check its performance.
