这项研究探讨了如何利用原生动物群作为巨大的活体微型机器群。原生动物的运动控制是利用眼虫的趋光性来实现的。蓝色激光扫描系统是为运动控制而设计的。其结构是蓝色激光通过两个检流扫描仪使激光进行二维定位，经凸透镜会聚后照射到实验池中。之后，蓝光通过高截止滤光片衰减，并由带有微距镜头的 CCD 相机记录。由于眼虫的趋光性反应较小，所以采用红色LED灯作为背景照明。实验结果表明，该系统可以通过沿扫描激光束聚集形成任意形状的眼虫群。它还可以控制眼虫群的运动，我们可以利用眼虫群作为微操纵系统来移动物体。
This study investigates how to use protozoa group as huge group of living micromachines. Motion control of proto- zoa is made by using the orientation phototaxis of Euglena. Blue laser scanning system is made for motion control. Its con- struction is that blue laser passed through two galvano-scanners to make the two dimensional positioning of laser possible, con- centrated by a convex lens and then irradiated into the experi- mental pool. After that, blue light is attenuated by high cut filter, and recorded by CCD camera with macro lens. Since there is little response of phototaxis of Euglena, red LED light is used for background illumination. Experimental results show that this system can make any shape of Euglena group by gathering along the scanned laser beam. It can also control the motion of an Euglena group, and we can move objects by using this Euglena group as a micro manipulation system.
