MIT Trains Robots To Jump 62

Nerval's Lobster writes: MIT just announced that its researchers have programmed a robotic cheetah that can leap over obstacles without a prompt from a human controller. The machine's onboard sensors rely on reflected laser-light to judge obstacles' distance and height, and use that data to fuel the algorithm for a safe jump. The robot's controlling algorithm takes into account such factors as the speed needed to launch its mass over the obstacle, the best position for a jump, and the amount of energy required from the onboard electric motor. As of this writing, the robot can clear 90 percent of obstacles on an open track. "A running jump is a truly dynamic behavior," Sangbae Kim, an assistant professor of mechanical engineering at MIT, is quoted as saying in a university press release. "You have to manage balance and energy, and be able to handle impact after landing. Our robot is specifically designed for those highly dynamic behaviors." For years, some tech pundits have worried that robots and software will gradually replace human workers in key industries such as manufacturing and IT administration. Now they have something else to fret over: Robots replacing the world's hurdlers.

    You know, somehow I'm betting a significant chunk of Slashdotters can't do a running jump without falling on their ass. ;-)

      It is not right to make fun of special people, and you should have some sensitivity training so you can appreciate your fellow Slashdoters: they don't fail to do a "running jump", they succeed in "falling on their ass" - if i was you, i would be ashamed for not understanding this... retard!

          It is not right to practice exclusions, and you need some diversity training to help you understand that everyone is a winner, including experts at falling on their ass - and don't call me an "insensitive clod"... fat ass!

    • Why should I run and jump when there is a perfect capable (and awesome) robot that can do it for me?

      Robots will take our jobs and our exercise routines!

  • Thanks MIT!!! Now we can't set up small barriers to stop the robots from making their advances.

    Not to mention it is a "robotic cheetah"... good luck out running that.

  • some tech pundits have worried that robots and software will gradually replace human workers in key industries such as manufacturing and IT administration

    "Some"? WTF??? Absolutely *ALL* the gizelle pundits are worried robots will replace actual cheetahs now.

  • Jumping Robots, cute. How about a Robot that can take a Nail out of Wood?
    • I cannot help but wonder of the judgement of my stating, "Hay MIT, how about building a robot that put a nail in a piece of wood?"
  • Is there a reason why all the obstacles are flat, low and pink? Can the lasers only see pink objects? What happens with higher/lower objects? What happens with irregular objects? What happens with different coloured objects? What happens on irregular ground?

    • Is there a reason why all the obstacles are flat, low and pink?

      Most likely because they already had some pink Styrofoam lying around.

      Can the lasers only see pink objects?

      Who cares? Obstacle detection with lasers is already a solved problem, and that was NOT the point of this research. The point is the algorithms and mechanism of jumping.

      • Most likely because they already had some pink Styrofoam lying around.

        If you actually look at the idea you will see that there is pink paper taped to white foam.

        Obstacle detection with lasers is already a solved problem,

        If all the obstacles have to be pink to be detected that might be an issue.

        • If all the obstacles have to be pink to be detected that might be an issue.

          Thousands of cars already have laser based obstacle detection that works in real time at highway speed. They work just fine with non-pink objects. They may have used pink in this instance just to make their image analysis easier. The color of the obstacles has no significance whatsoever to the basics of jumping and landing, and it is silly to fixate on that.

        I have my own personal reasons but MIT, as a whole, almost never fails to impress me. I even appreciate it when they put a car on the roof or make the roof into R2D2.

      I think you've just given them assignments B, C, D, and E :)

    • Is there a reason why all the obstacles are flat, low and pink?

      That's because the obstacles are meant to represent people gunned down by the robotic cheetah. Robot Cheetah will need to leap over them to gun down more people. Otherwise, we could just send wave after wave of men at the robot cheetahs until they are blocked in by corpses.

  • Looks like one of the Boston Dynamics machines. Also interesting is it seems to be self-powered and not with a noisy motor like Big Dog [youtube.com].
    • by KGIII ( 973947 )

      Boston Dynamics came out of MIT IIRC. I would not be totally surprised if they had something to do with it and it just was not mentioned in the summary. I, of course, did not RTFA. That is against the rules.

      • by Whiteox ( 919863 )

        Partially DARPA funded according to the FA with no mention of Boston Dynamics. That means the world will have jumping robotic military units in the near future. Looks like a pack animal though, so I envision it to be support or scouting. What it needs is a head and jaws with sharp fangs to be scary.

  • Next thing you know, the Daleks will climb stairs and there will be no escaping! (Yes, I know Daleks are not technically robots)
  • What I'm most impressed by with the videos is that it looks like the initial power for the jumping is coming from the front legs, rather than the back legs (which have more leverage).

    It seems to be the case (at least on one standing start [youtube.com] cheetah jump that I've seen, as well as a lion jump [youtube.com]) that the front legs are moved back for balance and the back legs used for the power push for the jump.

    • The reason why this thing uses the front legs for the initial vertical push is that the back legs are shorter than on most running animals. Notice when it's running that the back legs and front legs never overlap, while on an actual cheetah their back legs stretch forwards past the front legs in order to allow the more powerful hind muscles to do more of the work.
