本文探讨了原生动物能否被视为活的微操作器/执行器的可能性。原生动物的运动控制是利用负趋性电流进行的。首先，用直流电场对草履虫的基本性质进行了测试，结果表明草履虫可以通过电位梯度进行控制。通过使用八向碳电极池(电极距离4 mm，厚度0.2 mm)，操作者可以在瞄准方向上控制草履虫。利用图像处理技术和模糊控制方法实现了对原生动物运动的自动控制。提出了快速车削的控制方法。将这种方法应用到自动运动控制程序中，可以控制草履虫沿任意形状的导向路径运动。利用草履虫驱动旋转直径为0.5 mm的微型叶轮。这些事实表明，原生动物可以被用作微操作器/执行器。
This paper investigates the possibility as to whether protozoa can be treated as a living micro manipulator/actuator. Motion control of protozoa is made by using the negative galvanotaxis. First, a basic property test with a DC electric field showed that the Paramecium could be controlled by the electrical potential gradient. By using the eight-direction carbon electrode pool (4 mm electrode distance and 0.2 mm thickness), the operator can control the Paramecium in the aiming direction. Automatic motion control of protozoa is also achieved by using the image processing technology and fuzzy control method. The control method for rapid turning is also developed. To adopt this method to the automatic motion control program, Paramecium can be controlled along any shaped guide route. The actuation to rotate the micro-impeller (0.5 mm diameter) is achieved by Paramecium. These facts show that protozoa are able to be used as a micro manipulator/actuator.
