Here is a swarm of micro bristle robots that move forward by hopping on a surface that vibrates at 300Hz. Under different vibration conditions, a swarm of these robots can be controlled to disperse to different areas on the surface.
Zhijian Hao, Siddharth Mayya, Gennaro Notomista, Seth Hutchinson, Magnus Egerstedt, and Azadeh Ansari are behind this project.
