This paper describes the manipulation system by the motion controlled mass group of Euglena. A manipulation system in thin pool using scanning blue laser beam had been developed in the former study. Using this experimental system, an assembly of some two-dimensional plane shaped simple mechanical parts was achieved by the huge groups of Euglena. Transportation of high-density particle was also done by using a long rectangular plastic rod for the operation tool of the Euglena group. These manipulations, however, are limited in only two-dimensional thin layer. Therefore, in this study, the authors have been developing a new manipulation system in a deep vertical lengthwise pool by using a laser sheet beam to correct Euglena group and move them to the vertical direction. With the new system, it was succeeded to form group of euglena in arbitrary height and to follow the group after laser sheet along the vertical direction. The detail will be presented.
