Using tiny combustion engines to power very tiny robots

A team of mechanical engineers at Cornell University, working with a colleague from Technion-Israel Institute of Technology, has designed and built a tiny robot that is powered by a combustion engine. In their paper published in the journal Science, the group describes how they built their tiny engine and possible uses for it. Ryan Truby, with Northwestern University, has published a Perspective piece in the same journal issue outlining the work done by the team on this new effort.
