Laser defined and driven bio-inspired soft robots toward complex motion control.

The design and actuation of soft robots are targeted at extreme motion control as well as high functionalization. In spite of robot construction optimized by bio-concepts, its motion system is still hindered by multiple actuator assembly and reprogrammable control for complex motions. Herein, our recent work is summarized and an all-light solution is proposed and demonstrated using graphene-oxide-based soft robots. It will be shown that, with a highly localized light field, lasers can define actuators precisely to form "joints" and facilitate efficient energy storage and release to realize genuine complex motions.
