While a Mars rover can't operate upside down, the Hedgehog robot can function regardless of which side lands up.  "Hedgehog is a different kind of robot that would hop and tumble on the surface instead of rolling on wheels. It is shaped like a cube and can operate no matter which side it lands on," said Issa Nesnas, leader of the JPL team.
