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.

    If the scientists need any help writing the code that will drive their randomly bouncing robot scouts, I may be able to help them. I still have the source code to the bouncing ball applet I wrote in a class a couple years ago...

  3. That would be very hard to debug, IMO by smoondog · · Score: 3

    The problem with bounding robots, is that the communication time is so slow, they need to have something that can move very slowly and make very carefull movements. Remember the rover moved one step at a time controlled by earth. To have something moving randomly around would limit the ability of researchers to look at specific things and to be careful. -Moondog

  4. Distributed robotics for the Defense Department by rhea · · Score: 3
    Researchers at the University of Minnesota have been working on bouncing robotic scouts for some years now for the US Department of Defense. They pair the scouts with "ranger" units which transport them and then launch them. Potential applications include scouting behind enemy lines, counting the number of terrorists with guns and transmitting to a nearby helicopter, etc. Fascinating stuff.

    See the Center for Distributed Robotics website for lots of info, demos, etc. Or read this article from the UMN CS Dept Newsletter featuring this project.

  5. This reminds me by John+Jorsett · · Score: 3

    Just to prove there's nothing new under the sun, I recall seeing movies of an experimental WWII mine-clearing device that was essentially a heavy sphere that had some sort of rockets or other propellant devices. It would be launched and bound through an area in a random fashion, supposedly detonating any mines. It looked pretty hazardous to be around, so I don't think it was ever used, but it was quite entertaining to watch.

  6. Greenpeace? by Vuarnet · · Score: 3

    what damage will it to do the "planet" it is exploring? where is green-peace at a time like this.

    Greenpeace in Mars. Hmm. Would that make them Redpeace? Besides, we all know that Mars, that so-calledd "planet", has to be preserved in its pristine natural setting until we arrive in hordes, build MarsDisney themeparks and eat Earth chocolate bars.

  7. Are you kidding? by Anne+Marie · · Score: 3

    [W]hy would mother Nature tell us that we don't need to eat meat to get by in life while giving us sharpened teeth to eat meat better?

    We have neither the sharpened teeth nor the intestinal infrastructure necessary to be meat eaters. Besides, my point wasn't one of material necessity but of moral obligation. You don't *need* to eat meat; therefore, you *ought* not eat meat.

    But eating meat is a part of almost every human culture.

    I do frown upon senseless violence to animals

    Then don't kill them and eat their little bodies. It's entirely senseless.

    So's spousal abuse. Social prevalence does not make it anything more than just popular. People like beating their spouses and they like eating their meat. It doesn't help your point.

  8. Time to send space probes out in pairs again? by jamesc · · Score: 4
    No doubt L-M was properly roasted for its mistake, but I think it is time for the mission planners to go back to sending out pairs of probes again.

    Just like the Viking missions, two spacecraft give you two chances to succeed. They are launched at different times, in slightly different orbits. The arrival times are usually set to be a couple of weeks apart, mostly because of limited ground crew resources.

    If there had been two such Mars probes, after the first one crashed there might have been enough time to diagnose the bug and upload a fix before the second one arrived.

    Also, two probes do not cost twice as much as one. Only the launch costs are duplicated. The R&D costs are the same, and the money needed to build two one-off engineering prototypes (the probes) is less than twice that for building one.

    Ob disclaimer: I realize that some persistent defects in two mechanically and electrically similar probes will fail in the same way, and may very well not be fixable from the ground. But, that's no reason not to try.

  9. Picture by John+Jorsett · · Score: 4

    Here's a picture of the guts of the thing (which in government-speak, they call "Long Range Mesoscale Mobile Hopping Platform". Guess "hopper" doesn't cut it for the bureaucrats.)

  10. Hopper or Hole Digger? by martyb · · Score: 4

    First off, this sounds like a really interesting approach! It seems, at first, that it would go a long way to avoid problems with surface obstructions (e.g. large rocks).

    But, on further thought, can you imagine one of these things trying to hop out of a valley of loose sand? Sand gets kicked around, all right, but it'd be just digging itself in deeper and deeper! (It'd be even worse in an area where there was mud or a pond, but there's not too much of that on the moon <grin> and doubtful there'd be much on Mars.)

    Sure, you could make a larger "base". That is, the part that gets thrust against the surface. But, then there's another issue. From the article:

    On landing, the hopper's egglike shape allows it to pop back upright before reassessing its position, ready for the next leap.

    If you made the base larger, how would you make sure that it was on the bottom?

    Maybe a larger, birdcage-like superstructure? That might make it roll back into the proper orientation, but it would also add to the weight of the hopper and lessen its range. Further, it would risk the possibility of it getting mired in a crater:

    1. Hop!
    2. Hit side of crater.
    3. Roll to bottom of crater.
    4. Repeat.

    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?

  11. 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.
