Hobbyist One-Ups Sandia Labs 76

An anonymous reader writes "A robotics hobbyist has created what he claims is the world's smallest autonomous robot. The robot is half the volume of the robots produced by Sandia National Labs in 2001, moves quite a bit faster, and was made using techniques and supplies accessible to anyone." While Sandia Labs has had some time to improve on their original designs, it's still pretty cool to see what one can do at home as well.

    Why not place it in a box? I understand he doesn't have the sensor working to stop it from going off the table, why would he not then place it in a box as it looks like the device recognizes an obstacle and changes courses.

      Possibly because it would have been somewhat more difficult to film, because lighting levels would have been greatly reduced? Or else he wanted to showcase the robot's speed, which would not have been as effective inside a small cardboard box. He could have built a shallow cardboard border around the table, though.

      Perhaps he wanted to demonstrate that it did not have any edge detection capabilities?

  • Why do researchers keep wasting time on these stupid little robots? There's very little actually learnt from making an autonomous robot. So it's not for science.

      I teach electronics to a bunch of kids and use autonomous robotics as a vehicle for this.

      Kids really enjoy problem solving for things that move. This creates a great learning environment.

      Even plain old bump-and-turn robots have some very interesting control problems, like getting trapped. THis really helps people extend their problem solving skills.

      I also work in real-world robotics (big multi-ton mothers).Sure we use simulations for developing control ideas, but those are pretty limited. You can test out various theories, but simulation only takes you so far. You need the real thing to get the dynamcs correct. For some real fun you want to see a huge robot go out of control.

      Some of the most interesting research in robotics is being done at the hobbiest level. Lejos http://lejos.sourceforge.net/ [sourceforge.net] has some very interesting abstractions and models for defining and controlling behaviour. Then there's also http://www.seattlerobotics.org/ [seattlerobotics.org]

They just repeat the same work that has been done a hundred times.. get the exact same results.. and learn nothing new.. And there's the researchers at other labs that rarely publish papers (if at all) and when they do, the findings are the same as what others found 40 years ago.

        You learn from your mistakes, and there's no substitute for "the real thing." You can crash the robot in a sim over and over, and it's no big deal. Real destruction with sparks and fire teaches you life-lessons ... I had a summer job (many years ago) with a rather large gub'ment contractor. We were working on a robotic arm tasked with de-palletizing ammunition - ammunition of the 5-inch diameter variety. The second day at the site, the programming team had gotten the arm all twisted up after several hours of fussing with the control software. The design lead saw the "home" switch on the control panel, and decided that starting from a clean setup would streamline things.

        *** CRASH ! ***

        Nobody had programmed any obstructions within the cell, and some Genius had put the servo drive rack within the robots hemisphere of motion. The shortest path to the home location went directly through the servo drive rack. And when I say "directly through," I mean "ripped the rack in half." Literally. Big multi-ton mother, indeed.

        So there's a bunch of down time while equipment is replaced, and we're back on-site after about 3 weeks. To my surprise, the servo control rack is still within the robot's operating envelope, but the obstructions have been properly programmed. There's even a short demo where they try to move the arm into the obstruction, but the machine refuses (rather politely, I might add.) Several days of progress are made before the Brain Trust is at it again. One of the programmers decides it will be "cool" if the robot commits suicide - he'd been reading an Asmiov book if I recall correctly. So they program the BMTM arm to reach over and press the main power switch on the servo control rack. It refuses. So they place a piece of 3/4" black pipe in the end effector to create the necessary tool offset. Attempt number two goes [click] ...

        *** CRASH ! ***

        They had shut the main power breaker off, resulting in a rather ungraceful de-energizing event. Apparently the servo drives can "lurch" if power is abruptly removed. The arm stuffed the black pipe and the end effector halfway through the servo control rack ... which was thankfully de-energized.

        Not surprisingly, we were not invited back for a third attempt to program the arm.
    • It's basically a hobby and, as this hobbyist has shown, best left to the hobbyists.

      I hear that. I've been into RC for a long time, and although I never had one, I remember electric RC planes that were hand launched from 20 yrs ago. Whenever I see those recent Army commercials where the guy throws the recon plane into the air and acts like it's some high-tech shait, I just have to laugh. Bet the Army pays at least $10,000 for each of those, which you and me could build for $300.

    I'd like to see Emacs, the microbot, though... It makes toast, does taxes and raises your children, but unfortunately it has the size and weight of a phone book, draws a kilowatt of power and the wheels don't quite reach the ground.

  • Someone made a robot half the size of what Sandia made did six years ago. So this person had six years worth of COTS component improvements and six years to refine designs.

    I'm impressed. Truly. In high school I built a computer out of TTL chips. Wow, I sure one-upped Eniac.

    Sure the product is cool, but this is hardly a one-uppance.
    • Your poor analogy assumes that no one made a computer out of TTL chips (or anything smaller) between the time of Eniac and your high-school education.

      I don't doubt that Sandia could one-up pico with something new and 1/8th the size if they threw PhDs and hundreds of thousands of dollars at it. I hope they do - I'd like to see it.
      • by Excelcia (906188)
        Refinement isn't "one upping". Pico is an accomplishment, but it is hardly groundbreaking. The analogy is apt, because while designing a computer using TTL components is something of an accomplishment, it too is hardly groundbreaking.

"...it reacts to electric changes in the grid of electrodes it moves on. This grid also supplies the microrobot with the power needed to make these movements." While I'm impressed with the (incredibly) micro-bot, it still can't carry around its own juice.

    Why is the "smallest" consistently an issue when it comes to electronics and motorized equipment? They're being made smaller all the time. This will continue to be non-news headlines for some time to come.

    I'm not impressed at all. They're all using microcontrolers and ROMS and such. A researcher at Los Alamos developed stepper-motor driven insect-like robots using 12, 14, or 20 transistors that'd "learn" to walk, some with different speeds/strides, with no preprogramming and within a few attempts steps. They even developed what amount to social behavior when operated in groups. The more agile ones that could run would run over the smaller, slower ones. In groups, the latter gathered together and backed themselves into a circle, which prevented the larger, faster ones from running over them. The "beheavior" emerged from some very simple conditions, and stretches the definition of "behavior", much like the light-sensing toy cars exhibited in an old SciAm article. In both cases there's no real learning because there's no collecting of information to be used other than immediate feedback through hardwired circuits. But when you saw a table full of these "bugs" circle the wagons to protect themselves against the attacking "lobsters", it was hard to not think of it in those terms.
