    are excellent for getting kids interested in science/engineering. These sorts of things can be modified and are fun to learn so they're perfect. The prices are also relatively modest compared to other expenses.

    My rapid prototyping machine is the T-1000. The biggest problem is that it can't form complex machines. Guns and explosives have chemicals, moving parts. It doesn't work that way.

    I have to say, this is one of the most useful things I've seen on Slashdot in a while. For getting kids interested: my old middle school used to participate in a robotics league, which really got me interested in the whole idea of AI and computer programmming. There was too much demand: we could only send 16 people (8 per team) and every year 50 kids would show up. Let's get some schools to join...

  5. Excellent technique by Anonymous Coward · · Score: 4, Interesting

    While it may look Mickey Mouse, building a prototype with Lego can save a huge amount of time. It is very easy to get a working system using Lego. I've had students build pick and place robots and conveyer systems with Lego. That's step one. At that point you have a working system consisting of mechanical parts, electrical parts, driver circuits and software.

    Step two is to replace part of the system with the real item. Repeat step two until you have a complete system comprised of 'real' parts. Then, you're done.

    The beauty of this approach is that you are always dealing with a working system. If you build a part and it doesn't work, then that's what you have to fix. The alternative, where you build all the parts and assemble them and hope it all works, doesn't give you that advantage. If the system doesn't work, you don't know which part to fix first.

  6. Is this a really a robot? by rufusdufus · · Score: 4, Interesting

    I saw my first homemade robot well before the PC ever came out. It was made by a guy with only rudimentary electronics skill; he used a blow torch as a soldering iron. The thing didn't do much, drove around and moved its arm up and down and it had a great gripping arm. But from what I see on this page, it did a lot more than this "robot" from the year 2005 can do.
    Is this thing anything more than a very expensive remote-control car minus the remote? I don't see any reference to sensors and feedback. Without some sort of sensor/feedback mechanism, some sort of intelligent behavior, I wouldnt call it a robot.

    After skimming TFA, this idea seems all well and good. However, this immediately brought to mind Lego Mindstorms.

    Besides, with Legos, you don't have to have power tools. Just your handy dany digits.

  8. most useful thing for physical prototyping by Mungkie · · Score: 5, Informative

    Some stuff called polymorph (a trade name I think?) it's a thermo plastic that becomes maleable in boiling water and sets tougher than most other plastics. Perfect for making parts for almost anything that is not heated above 50'C.

    Tools wise a dremmel type drill, lathe, set of files, hacksaw, and a screwdriver.

  10. OMNI Magazine story on prototype robots in '81 by RancidPickle · · Score: 4, Interesting

    Back in the early 1980-1981 era, OMNI magazine had a great artical on building prototype robots that thought like insects. The gent in charge of the program at MIT decided that it would be a good idea to begin a robotic life at the insect level, then build (evolve?) from there. He used toy cars from Radio Shack, and they had programmed responses, such as flee when the lights came on, following tail-lights, and setting up a territory.

    When the robots started doing odd things, they learned quite a lot. One thing that was programmed into the bugs was to defend a territory. The bugs would run a perimeter, and if another robot had tresspassed, they would park and shine their headlights on each other. Theoretically, they should have stayed locked this way, but sometimes one would give up and stake out a new territory.

    They were using this for prototyping, and I wonder how far they've come since 1981.
