Sure, Mindstorms NXT is a toy, but it is an important toy, like a piano or a chemistry set. It's one of those items that engages an imagination and possibly opens doors to new interests. Since our future is surely to be shared with robots--it's already started happening, just look at Roomba--those robots will need, at least initially, humans to program and maintain them. Those people, years from now, will likely remember their experiences with Lego Mindstorms.
Out of the Box
The main part of the kit is the NXT itself. It's about the size of an iPod (though a bit thicker) with a a loudspeaker, a monochrome LCD, and navigation keys on the front. This is the controller for the robot--it's brain, if you will. It has three ports on top for connecting to the servo motors and four ports on the bottom for connecting to four different sensors: Touch, Light, Sound, and Ultrasonic (see detail below).

The set includes Ethernet-like wires for connecting all of these to the NXT, as well as software and a basic USB cable for downloading programs from your computer. Then there are all the Lego parts, hundreds of them, and most are very small. It would be a good idea to get a plastic organizer for the different parts--it would not only make construction and storage easier but also part loss less likely.
Hitting the Bricks
The instructions for MNXT are simple, illustrated, and they gently take the new user on an introductory path through the system. The quick start guide promises a 30-minute robot building and programing intro, though for me it was closer to 50 (I'm a little old and slow). It starts with a simple diagnostic routine which shows you how to test the function of all sensors, then proceeds to step-by-step picture instructions for building a basic first robot. It's about as complex as building a piece of Ikea furniture.
Programming is the real gem in this system. It has a drag-and-drop interface using pre-programmed objects that you pull from a palette and snap to other objects. |
Next, I installed the software. Be sure to check the system requirements (below). The software is well-designed and very intuitive. It comes with built-in video instructions on how to create your first simple program and download it to your NXT.
Bringing It To Life
Programming is the real gem in this system. It has a drag-and-drop interface using pre-programmed objects that you pull from a palette and snap to other objects. Each object is configurable. For example, the Sound object brings up a sub-window that allows you to choose between a tone and a list of sound files, set the volume, set duration, and so on. Little Lego bricks between the objects reinforce the idea that building a NXT program is like building a Lego model. Programming this way is much easier than, say, creating a web page from scratch. Lego even offers a software development kit for getting deeper into the programming.

| Mindstorms NXT "challenges" from top: Tribot, RoboArm, and Spike. |
There comes a genuine thrill from seeing something you've created--even something simple and silly as my first program--come to life in a robot. It's akin to seeing yourself on TV for the first time. I played that program a dozen times.
The software contains "challenges," which are similar step-by-step instructions for creating and programming more complex models, such as a robotic arm that can "perform simple tasks and react to different colors." Each challenge is divided into smaller tasks with step-by-step building, programming, and testing guides for each task.
Accessing your latest program once it's downloaded to the NXT is pretty easy. Lego has set it up so that you can execute it by pressing the big orange center button four times in a row after start-up. I was surprised to find out that you don't need a computer to program the NXT. You can program directly into the NXT Program submenu.
Bluetooth Ready
The NXT also has built-in Bluetooth wireless technology. If your computer has Bluetooth, you can test and download programs to the NXT without connecting the USB cable--a really handy feature if you're programming a complicated dance routine and you don't want your robot getting tripped up in cables. If your phone or PDA has Bluetooth, you might be able to use your device to control the robot. Best of all, Bluetooth allows you to create a network of up to three NXT devices. Think of the possibilities: three NXTs plus three sets of blocks and sensors equals bigger, more complex robots.
My one and only complaint is that I wish the sensors had more "studs," those little round parts that allows Lego bricks to interlock. --Porter B. Hall

I'm a parent of two (6 and 3-year old) so this is mainly for me for now. I was an early adopter of the first generation of Mindstorms, so naturally I pre-ordered the NXT. I've played with it for two hours, so these are my initial impressions:- the new motors are Wonderful -- they work as motors or servos (you tell them which angle to go to). They look futuristic and robot-y - it comes with an ultrasound distance sensor -- whoa that's neat! - All of the sensors are "slick-looking", and seem to work very well. - the brick display is quite nice, but the interface is a bit niggly. Lots of nested menus. My 3 year-old managed to delete the built in demo program by button twiddling. It was easy to restore, though. - the box itself (the "out of box experience") is disappointing. You have to punch out some quarter-circles to allow it to hinge, but they're poorly serrated, so the tears... Read more 217 of 228 people found the following review helpful: A great toy! But, an even better learning tool., By This review is from: LEGO Mindstorms NXT (Toy) I built my first robot out of a cardboard box (I was inside) and, at the time that was pretty much the same way they did it on TV and in the movies. We've come a long way since then!My entry point to the NXT robotic platform was in search of a faster, easier way of implementing remote sensing and data accumulation. I had been working with Crossbow motes, but found their "programming" tedious and non-intuitive. I checked out LabView first ($1,000 for the base level) and figured that for a quarter of that price I would get a taste of the software plus ready-to-use sensors and servomotors. I was pleased beyond my most optimistic expectations! I won't repeat the other reviews other than to say that the first "rover" was done in less than 30 minutes (once I figured out that its parts were in the smaller box labeled "open me first") and I am a long way from being a Lego wizard. What I want to do is clear up some of the confusion that might result from... Read more 70 of 73 people found the following review helpful: Very fun introduction into robotics. Great for kids AND adults, By This review is from: LEGO Mindstorms NXT (Toy) Lego has again released a ground breaking product. This is a great way for anyone to get into robotics. No tools are necessary, not even a screwdriver. Everything is built using lego blocks. These are not the lego blocks that you might be used to. They are not the studded ones that snap together. These are Technic blocks ("studless legos"), which create a more human, less boxy look.Everything talks to the central computer, which is called a "brick". It is maybe 1/4th the size of a "real brick". It has ports to connect to the four sensors and three servo motors. Additionally, the brick can connect to a computer using USB or bluetooth. The three motors are controlled using your own programs. You have a great deal of control, you can specify the exact angle a motor should move. Also programming is easy, using a visual block-dragging software application. It works great on both Mac and Windows. The four sensors are very cool... Read more |
