New robot bee may soon be a spy's secret weapon

People fear robots are becoming too human, but, in reality, robots are becoming a little more bug-like every day.

A team of Harvard University researchers proved this axiom when they found the solution to extending tiny robot flight is by mimicking the way small bugs alight on walls and ceilings.

The applications for such a robot are wide-ranging, from small spying devices that can conduct surveillance missions while suspended from a ceiling to research drones that can allow scientists to take measurements where no other sensors can physically go.
