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.
