The past five to ten years have seen the birth of microbotics. A whole range of components that are vital for building robots, such as actuators, motors or batteries, became available in micro-scale only fairly recently. Finally enthusiasts got what they needed to put their own systems together, and the whole field benefited from their work. But there are obvious limitations to scaling down robots full of sensors, motors, and other mechanisms. That is, unless you make the machines extremely simple, which is exactly what Ron Pelrine of SRI International has done. His work on levitated microrobots may have powerful implications for robotics, and is likely to bring us a step closer towards fast, precise and affordable robotic systems comprising thousands, if not millions of microrobots.
