NASA space copter ready for first Mars flight

The helicopter that NASA has placed on Mars could make its first flight over the Red Planet within two days after a successful initial test of its rotors, the US space agency said Friday.

The smallest motor in the world

A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor ...

Locked movement in molecular motor and rotor

For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. University of Groningen organic chemists led by professor Ben Feringa are the first to achieve ...

Scientists simulate tiny bacteria-powered 'windfarm'

A team of scientists from Oxford University has shown how the natural movement of bacteria could be harnessed to assemble and power microscopic 'windfarms' - or other man-made micromachines such as smartphone components.

A folding drone that's ready for takeoff in a snap

Thanks to the power of its rotors, this fold-up quadrotor extends its articulated arms and takes off in a fraction of a second. This prototype will be viewed by specialists on May 25 at the International Conference on Robotics ...
