This paper describes the automatic manipulation system by the motion controlled mass 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. We can transport the object by Euglena group by making collision to the Euglena group to the object and moving the scanning laser to move the Euglena group. In this study, a plastic rectangular rod was transported to the aiming position by using this system. We have to use visual feedback control program to decide the laser irradiating position to achieve the stable transportation preventing the wear or the adsorption. Simple two-dimensional shaped mechanical parts are assembled by Euglena group. Therefore, we can use Euglena as living micromachines.
