A newly developed microrobot defies the force of gravity by flying or levitating, powered by a magnetic field. It moves around and dexterously manipulates objects with magnets attached to microgrippers, remotely controlled by a laser-focusing beam. (Credit: Image courtesy of University of Waterloo)
From Science Daily:
ScienceDaily (Apr. 14, 2009) — A University of Waterloo engineering research team has developed the world's first flying microrobot capable of manipulating objects for microscale applications.
The microrobot discovery provides researchers with more control over the microscale environment, allowing them to move and place tiny objects with far greater precision. The microscale deals with tiny objects, at levels that are too small to be manipulated by humans.
