AndreV writes "A University of Waterloo in Ontario engineering research team has developed the world's first flying micro-robot capable of manipulating objects for micro-scale applications, which include micro-assembly of mechanical components, handling of biological samples and even microsurgery. It moves around and manipulates objects with micro-grippers, remotely controlled by a laser-focusing beam (heating the pincers with a laser opens them; when the laser is turned off, they cool and close). Its magnetic drive mechanism controls the field using continuous feedback from positioning sensors in order to position the 'bot. 'It can enter virtually any space and can be operated in a sealed enclosure by a person outside,' the project leaders says, 'which makes it useful for handling bio-hazardous materials or working in vacuum chambers and clean rooms.' The video of the contraption shows it floating in mid-air."
