Abstract
This paper describes the automatic manipulation system by the motion controlled mas group of Euglena. The group of Euglena was formed by the scanned blue laser beam. Euglena gather around the blue laser by their positive orientation phototaxis. In the previous reports, the transportation of a recutangular plastic film was manipulated by the formation controlled Euglena group. The angle of the object can be controlled by using Euglena group and visual feedback control program. In this report, some two-dimensional plane shaped simple mechanical parts assembly was achieved by Euglena group controlled by the visual feedback control program. The detail will be presented.
