Bouncing Robots Exploring Planets?

revision1_1 writes: "New bouncing robots could advance planetary exploration by leaps and bounds. The exploration of other planets could benefit from a giant leap for robot-kind, according to researchers in New Mexico. Rather than use wheels or legs, robots could rove across alien landscapes far more effectively by bounding over the surface in an almost random fashion, they say." Well, science hasn't given me talking fruit and a jet pack yet, but this looks pretty close.

    Same kinds of problems if it should land in a narrow ravine... it could hop itself right across to the other side of the ravine and imbed itself in that wall.

    I'd like to think they've considered these problems, but I saw no mention of them in the article. Any other ideas on potential problems and their solutions?

  112. Are you insane? by karma_policeman · · Score: 4
    I'm not sure that it's really all that wise to be sending all kinds of junk all over Mars. Now instead of 1 little wheeled thing per mission we could have dozens of bouncing machines littering the planet.

    That sounds like environmentalism taken quite a bit too far. That is almost as bad as the people who think we shouldn't colonize mars because "we'll just ruin it like we ruined earth". Nevermind that there's nothing on Mars to be ruined. No evidence of life, just thousands of acres of dust.

    If bouncing "litter" helps us one little bit in exploring mars, I say go for it. Mars isn't doing us any good just sitting there, all pristine.

    Leave it to us humans to destroy the beauty of planets that we have yet to even inhabit with bouncing bundles of robotic goodness.
