Microbots Made of Bubbles Have Engines Made of Lasers

We’re used to thinking of robots as mechanical entities, but at very small scales, it sometimes becomes easier to use existing structures (like microorganisms that respond to magnetic fields or even swarms of bacteria) instead of trying to design and construct one (or lots) of teeny tiny artificial machines. Aaron Ohta’s lab at the¬†University of Hawaii at Manoa has come up with a novel new way of creating non-mechanical microbots quite literally out of thin air, using robots made of bubbles with engines made of lasers….
