This little robot can jump three feet in the air

In the future, flocks of small, one-footed robots may bound across areas too dangerous for humans to traverse, carrying out search and rescue operations. They'll be able to leap across rubble like monopodal kangaroos. Today, their predecessor prototype tends to fall over after most jumps. The landing needs work, but the jumps themselves are impressive. The robot, SALTO, can leap up to a meter into the air.
