Micro-nano robots intended for application to various fields are developed. However, motors, which are robot's power, are not yet practical. In this paper, to realize the motor, which can be applied to micro-nano robot's power source, we established bio-motor by using surface swarming of Vibrio alginolyticus. We succeeded in controlling movement of surface swarming by ratchet shape micro channel and then driving the micro gear in the closed micro channel. As a next step, to transmit power of rotational movement, we fabricated the open micro channel and micro object (floating pillar, micro gear etc.) and succeeded in driving the object in the open micro channel. In addition, we revealed that rotational power of floating pillar by deformation of nano probe. Finally, we assembled the micro gear with shaft like crank. Therefore, it became possible transmitting the power from rotational movement to outside. Thus, we achieved to construct base of bio-motor.
