Abstract

We propose an elastomeric microrobot actuated by ATP-driven biological traction of actomyosin. Our robot is composed of a PDMS thin film part as a body and an actomyosin-embedded collagen hydrogel part as a linear motor. The actomyosin drives the hydrogel linear motor by the hydrolysis of ATP. This actomyosin linear motor could repeatably contract by adding ATP and stretching similar to the driving mechanism of our body. By combining the linear motor part and PDMS actuator part, we succeeded in driving the whole device by the traction force of actomyosin. The traction force generated by the linear motor was estimated from the deformation of the PDMS body. We believe that our device would be a new approach to apply biological motor for micro actuators.
