    Or you might be interested in the OrcBoard robotic controller [orcboard.org], which is open source (schematics, layout, firmware, userland tools all GPL). It's being used by a number of robotics classes (6.188 [mit.edu], 2.12 [mit.edu]), and a robotics competition (MASLab [mit.edu]) at MIT.

    It's a bit different than mindstorms in that it's designed to be used as a slave to a laptop or other more CPU-rich device. But you can use it in stand-alone mode too, if your robots are simple.

          Additionally, the Mindstorms controller supports bluetooth communication, which is a very nice feature.

    Fans of SNOT (Studs Not On Top) Lego design will love this kit, because there aren't any studs. It looks like everything's designed to hook together with Technic axles and connectors, and no "basic brick" connectivity.

    When I was a FIRST Lego League coach, the designs often embedded motors, sensors, even the RCX as part of the structure. The latter was usually a bad, bad, idea, since you'd have to disassemble major parts of your bot to replace batteries, and during a competition, you'd replace batteries every other run.

    I welcome the sensor-laden motors, bluetooth, ultrasonic 'vision'... but I wonder if they've beefed up the programming any. Lack of backward compatibility is a surprise -- I've got a number of old sensors and motors.

    There were plenty of strategic blunders behind the dismal results: a misguided foray into making PC software games, expensive licensing arrangements (chiefly with Disney), and designs that puzzled rather than entertained.

    I grew up playing with RCX 1.0 and Wired seems to have somehow portrayed it as a failure...

        (From one of the images, I'm guessing of a magazine spread)

    "Building Blocks" - "Two-by-four" lego blocks vs. Technic Blocks a.k.a. Studless legos
    -Okay, firstly "Technic" was a brand of lego's geared towards the technological kids like me who liked to play with motors and buttons. Second, the RCX had 4 holes that could be used with studless legos anyway, all they did with this new thing was add a few more and take off the studs.

    "User Interface" - "Non-intuitive interface, RCX Code Commands, PC Only" vs "Intuitive GUI, drag-and-drop icons, PC and Mac"
    -Whoever said RCX 1.0 wasn't intuitive is crazy, programming with the RCX was about the most basic type of programming I've ever done in my life. You dragged little blocks around to configure the order of the program. You would drag, for example a "Wait Ten Seconds" green block over someplace and then put a "Turn the motor on" purple block right below it. Then you'd download it to your brick (okay, this was a little sketchy at times with IR) then turn it on, select the number of the program and press play. How much simpler could you get? Not to mention it had tutorials that showed everything down to animating how to put in the batteries.

    "Power" - "Two Motors" vs. "Three motors, redesigned for smoother operation"
    -Uh, actually the RCX could power up to three motors too, it just typically came with two.

    "Connectors" - "Two-wire analog cables" vs "Six-wire digital cables"
    -Well yeah, the more the better, but I'd imagine homebrew stuff is simpler than digital, I've never done any so correct me if I'm wrong

    I've always heard about Wired being sketchy about their reporting, grr...

    I currently own an RIS, and I rarely mess with it (mainly because I have waaaay too many other projects to do so). I love Lego, ever since I was a child (one of my first real Lego kits was the Expert Builder crane - can't remember the number right now). When the RIS came out, I had to have it, so I bought it, and then later bought a couple of upgrade kits (the remote control/sensor pack and the expansion parts kits). But something always disappointed me, and the NXT seems to be the same way:

    Not enough I/O ports!

    On the NXT, if you look closely, you are still limited to three motor outputs (that fourth port on the controller at the "top" is for USB). As for inputs, there still seems to be a limit of 3 general purpose inputs, plus one extra "special" ultrasonic input (it is strange - they mark the other inputs on the controller brick, but leave the ultrasonic unmarked - I have to assume that it is meant for the ultrasonic sensor only).

    What if you want to hook up more sensors, or more motors? What if you want to hook up old sensors and motors, how do you do that? From what it appears, you can't - you can only hook up the same number of motors and sensors as the old RIS (minus the special ultrasonic sensor).

    This is what makes me wonder whether Lego is paying attention at all to the market they created. For anyone who has perused the websites of Lego RIS creators, they will quickly learn that there are a few things that these people want: more motor outputs and more sensor inputs (witness the number of people creating numerous schemes to allow multiplexing of the I/O space), a greater variety of sensor types (witness the number of people making and selling custom sensors), and an easy/efficient way to network the controller bricks.

    I will go further to say that there are many people who would love to see more than just motors - I know of some builders who have taken miniature pneumatic solenoid switches and converted them to allow them to control Lego pneumatics. How about a real Lego pneumatic pump (instead of having to build one from parts - although there are a ton of ingenious designs)? How about a Lego linear actuator (I have seen people build these too from Lego mini-motors and worm gears)? Why not a Lego stepper motor?

    Furthermore, all of this could have been built into the same four-stud plate electrical connector - even the new motors with their in-built rotation sensors could have used this (two wires for power, one or two for the sensor). You would have to maybe round/notch the corner of the plate to indicate "pin 1" (like an IC chip), and you would need to add some additional protection (maybe diodes or something) for n00bi3s who connect the lines wrong, but it could be done. Standardize the motor output pins on the place (and sensor input pins) to be the same as current motors and sensor hookups. If done right, all the old stuff could work with this system, and new parts, like the new motors and sensors, could be added as well. Or, go with the current RJ jacks, and add dongles to connect old sensors/motors (maybe they will do this - I can assure you if they don't, someone else will).

    Ultimately, at the minimum, they really need more I/O jacks for more motors and sensors, and a way to easily network the controller bricks. Perhaps the USB port will facilitate the networking of the controllers (?) - we won't know until people start playing with them. If Lego was smart, they would release a "super-controller" that had more I/O for those who want it and need it. It seems strange that the original Lego controllers developed at MIT had way more I/O capability than this new controller. There is no valid excuse, unless they just want to avoid confusion (which I can't understand, because they don't seem to understand that young kids are not really their target market for Mindstorms).

    For myself, I am finding that if I want to do any kind of real development of robotics, it is just best to stick to breadboards, a soldering iron, PIC controllers and/or BASIC Stamps, hobby R/C se

    • It is high-grade, precision engineeered plastic. The LEGO robotics sets are made from lots of pieces of various shapes, not just one shape replicated thousands of times. Compare up against some of the LEGO knock-offs that are much cheaper. They hold together when you're building a static building, but if you try to build something that moves, they fall to pieces. You need plastic that fits *exactly* so that gears don't grind against each other and torque doesn't tear the robot apart. Personally, I'm impress
    • The previous Mindstorms RCX had 3 inputs and 3 outputs.
      • 8 power setting motors

        Not really, though. The outputs are really just on or off, but if you toggle them fast enough you can emulate a whole range of output voltages. Which, incidentally, is what the horribly limited system the RCX ships with does, though so slowly that the motors make wicked grinding noises (well, at least mine do) if you run them at anything less than full speed.

    • There are actually many ways to program the original Mindstorms RCX. Although initially the only language was the one it came with, it was soon hacked. Languages were developed that took advantage of the default firmware (NQC), but many more were created that completely replaced the existing firmware. You could cross-compile C for it, and there was also a tiny Java VM that ran on it. Neither of these offloaded stuff to the PC.

      I'll try to dispel some myths here without stepping on the toes of my former employer, National Instruments, which is working with LEGO on the software interface and programming environment for this product. I designed and built the compiler infrastructure (excepting the parser) for targeting the virtual machine running on the brick from a program built in the Mindstorms NXT software environment, so I speak with some authority (and little fear of reprisal as long as I stay within reasonable limits in discussing as-of-yet unpublished details :)).

      If anything, this product is designed to be more extensible than ever. They *want* third party providers to create new hardware and augment the software environment to support it. We built the brick's virtual machine with the understanding that the prior one was extremely limited for C-style programming languages that operate with a stack and a flat memory space. It is still more oriented with the highly parallel nature of the dataflow programming language kids will use, but this should only make things more interesting for the C/compiler hackers and enthusiasts out there.

      Finally, the entire compiler was written in LabVIEW itself, which is the dataflow programming language that the Mindstorms NXT programming environment is based on. The LabVIEW-based compiler can parse, analyze, optimize and generate code for other LabVIEW programs, so theoretically the programming environment provided by the product is all the enthusiast or third party needs to extend the product with new functionality. In reality, much of the API used by the compiler won't be initially available to everyone, mostly because that's not what the product is really about -- but this is mostly a matter of time and resources since they're on an aggressive schedule, and it's only a matter of time before they provide an SDK.

      They want this product to be accessible, and have nothing to lose by doing so. Fortunately this time however the underlying technology was designed to make this even easier after the product launches.

      One last request to NI is something that we discussed while I still worked there... Since NI is not ultimately a compiler company, I'd love to see the compiler open-sourced for anyone with access to LabVIEW or Mindstorms NXT. How 'bout it Joel? I've still got some G in me.

      -Robert Morton

      p.s. I left NI on very good terms, and I hope I didn't just undo that :) I'm at Intel now, focusing more closely on the types of performance analysis on which I am so keen, but NI continues to do amazing work, both for its customers and the community.
