Penelope Boston and Steven Dubowsky have received some bling-bling in the form of a grant to design hopping microbots for NASA. A rover would deliver hundreds of these miniature robots to the Mars surface for exploration purposes. The small spheres store up muscle energy and release it causing it to hop into various directions. The microbots would be able to analyze the surface material and map out the planet.
