An anonymous reader writes "IEEE Spectrum reports on a rover design being developed at NASA Ames Research Center: Super Ball Bot. The premise is that the rover's brain and scientific equipment would be suspended in the center of a structure made of rigid rods and elastic cables. The rods and cables would be deformable, allowing the rover to roll over complex terrain without damage. This design would be ideal for exploring a place like Saturn's moon Titan. Its atmosphere is thick enough that a probe could drop the rover from 100km above the surface, and it would survive the fall without a parachute. 'In a scenario studied by the team (PDF), the robot could be collapsed to a very compact configuration for launch. Once it reaches the moon, it would pop open and drop to the surface, flexing and absorbing the force of impact. By shortening and lengthening the cables that connect its rigid components, the ball bot could then roll about the surface. These same cables could be used to pull back parts of the robot, so that science instruments at the center could be exposed and used.'"
