World's first directly light powered walking device

Scientists have developed a polymer film with liquid crystals, that can undulate under the influence of light. They clamped a strip of this material in a rectangular frame, and it goes for a walk all on its own when illuminated. This research, performed by scientists of Eindhoven University of Technology and Kent State University, was published in Nature on 29 June 2017 (DOI 10.1038/nature22987).

The video runs on real speed, the device is 2 centimeters long.
