We have been investigating how to use behavior-controlled Daphnia as a living micromachine. The control of Daphnia was done by applying their phototaxes. We have developed an operation tool for Daphnia for the object transportation on the water surface. In this study, we developed underwater operation tools for Daphnia. We installed an operational tool called 'Y-Wing custom' to the Daphnia's back and investigated the vertical object transportation performance of the tool installed Daphnia. In the beginning of the development, the attached tool disturbed Daphnia's swimming, and the object transportation performance of the Daphnia with operational tool was not improved comparing to the Daphnia without any tool. After the improvement of the tool shape, and total buoyancy, we succeeded to move and drop a nylon ball on the shelf from the designated end point of the shelf by manually controlled Daphnia in the vertical plane pool in the upright posture.
