Abstract
In this paper, we proposed large motion control pools of paramecium by applying electrical field. To prevent the pH change in the experimental area, the culture media in the electrodes area of the pool is exchangeable by the micro tube pump. The experimental area and the electrodes area are separated by the membrane filter to keep electrical conductivity and to prevent the going in and out of the culture media. By this design, we can set the electrodes distance as 11mm. We made two types of the pool. One is fixed eight electrodes (four pairs of the counter electrodes) type that is the same as our former studies. The other is the electrodes rotatable type to improve the resolution of the electrical field application angle. This type pool has four electrodes (two pairs of the counter electrodes). A servo motor is used to rotate the electrodes. By using these pools and improved motion control algorism, the controllability of the paramecium was much improved. In the case of the electrodes rotation pool, the average control deviation was 0.149mm.
