BigDog Robot Grabs, Lifts, and Throws Cinder Blocks With Its New Arm 91

Posted by Soulskill from the please-don't-teach-it-to-aim-for-humans dept.
cylonlover writes "Boston Dynamics' BigDog may have already been replaced by the beefier LS3, but that doesn't mean it's totally obsolete. Today the company unveiled a version of the quadruped equipped with an arm where a head (or tail) would go. As can be seen in a slightly disquieting video, it's powerful enough to lift and toss a heavy cinder block. Key to this work, funded by the U.S. Army Research Laboratory, is that BigDog uses the dynamic forces of its whole body to help it throw the cinder block. It begins by taking several steps to the side before quickly accelerating as it swings its arm, temporarily launching itself into the air in the process. This approach is similar to the way an athlete winds up before throwing a discus, for example, and greatly enhances the robot's throwing power. Since few robots are as capable as BigDog when it comes to balance, it's an excellent platform to test these sorts of strenuous actions."

    Considering the military is preparing for a future of cyber warfare. I find it interesting that we are willing to put war fighters into suits that assist with body movements. You know they will have connectivity eventually. I mean, what if the Chinese hack into the systems that control these suits. They would have a whole battalion playing twister in no time :)

Put a hopper on top of that thing so it can load and haul a few blocks at a time and it would be invaluable to a masonry worker for fetching blocks for a job instead of a helper or the masonry person him/herself having to haul them....would be very handy...

  • What sort of current is in-flowing through those cables?

    Will that chassis support batteries which will make the thing function? If so, for how long? What's the recharge time?

    Until the robots are running on some sort of power which allows dynamic recharge and sustained off-grid operations, all one has to do is outrun them until their batteries run down.

      That chassis supports batteries since 2008 when they demonstrated the fucking thing in their parking lot. And if not batteries it could probably run with a diesel generator.

      The cables are there because
      1.It's easier to develop a device that you can run without swapping batteries all the time
      2. Support cables to prevent it from falling over when you test and fine tune the movement algorithms

      That cinder block weights what? 20 kg?
      It throws it about 2 meters high in half a second...

      This gives a power output of 0.5 * 20 * 9.8 * 2 = 196 W Let's assume that there are inefficiencies and I guessed low on height and weight so peak output would be in the ballpark of 1kW

      Say it's powered by a car battery.
      A car battery is about 40Ah at 12V = 480Wh or 0.5 kWh

      What that comes down to, is that humans don't *need* electrical power to merely function. We certainly *like* electrical power, but if it were us versus computers/robots, cut the power, the batteries only last so long, then disassemble them.

      Even if they're guarding all of the power stations and somehow manage to operate them without humans (which is currently impossible), there's absolutely no way to guard all of the power distribution.

        This part of your post made me think of something: while we certainly *like* electrical and gas power for a lot of convenience and we can certainly live without watching the latest popular TV show, we do sorta depend on it for food. I suppose most farm equipment is still mostly mechanical powered by gas/diesel, but I don't think we can continue to feed 7 billion people without the help of machines. I don't think this affects our outcome in a robot revolution, just something interesting that your post induce
