Harvard university's "RoboBee" has become the lightest vehicle to ever achieve untethered flight.

This means it doesn't require jumping or liftoff.

The little robot -- which weighs 259 milligrams -- relies on solar cells and an extra pair of wings to achieve the lift and power needed to fly on its own.

Details of this development were published this month in the journal "Nature."

RoboBee's developers' next goal is to decrease the power the robot requires and add on-board controls that will let it fly outside.
