then the Download link will download a compressed folder (.zip file) containing the program file(s) for the project. Your computer must be able to read zip files to read these. Most newer computers can read and open zip files directly, and you will be able to see the files inside after downloading it and selecting 'Open' when prompted for what to do with the file. On some computers, you may need to download and install an 'unzip' utility (many are available for free). On some systems, you may need to save the .zip file to a location on your computer before opening/unzipping it if it will not open directly.
Alternately, if the project instructions link directly to a program file in the description such as the Power_Saw program, then the program file is uncompressed and will download directly.

Once you reach an NXT program file (.rbt), you can either save it to a location on your computer, or open it directly. In either case, you will need the LEGO MINDSTORMS NXT software installed to read it (see below).
Required Software
The downloadable programs for the projects (.rbt files) are written using the NXT-G programming system, which requires the LEGO MINDSTORMS NXT software to be installed in order to view them, edit them, or download them to the NXT brick. The program files cannot be used with RoboLab or any of the other NXT programming systems, not can they be viewed in standard text/graphics programs such as Microsoft Word or Adobe Reader.
Mindstorms Tribot Program
| Note: The NXT 2.0 projects require the NXT 2.0 version of the software, which comes with the 8547 set. If you are using the LEGO Education software, the LEGO Education NXT-G 2.1 software is required to use any programs that use the color sensor or the Pack-and-Go (.rbtx) format, otherwise the LEGO Education NXT-G 2.0 software will work with most 2.0 programs. The NXT 1.0 projects will load and run in any version of the NXT software. |
If you have the LEGO MINDSTORMS NXT software installed, then a program file (.rbt) will automatically load into the NXT-G programming system when you open the file.

Press the Open button to load the program into the NXT-G programming system. |
Downloading Programs to the NXTAfter the program file loads into the NXT-G programming system, you download it to the robot by connecting the USB cable to the NXT brick and pressing the Download button on the controller in the lower right corner of the NXT-G window. |
Errors Trying to Load or Compile a Downloaded Program
All of the program (.rbt) files on nxtprograms.com should load, compile and upload to your NXT through the standard NXT software without any additional software, if you have a suitable version of the NXT software installed, as explained in the Required Software section above.
If you are getting 'Error 5002' or 'The program is broken. It may be missing required files', you are most likely trying to load an NXT 2.0 program into the NXT 1.X or other older version of the software.
Ftp Synchronizer Professional Serial Numbers. Convert Ftp Synchronizer Professional trail version to full software. 
If you have the correct NXT software installed but you still get an error trying to load or compile a downloaded program such as 'Invalid program file', or 'Internal Compiler Error', it is possible that the file was not downloaded completely by your browser or was corrupted. The .rbt files are large and may fail to download completely in some cases. If this happens, try downloading the program again.
Saving Changes to a Program
Lego Mindstorms Program
If you open a program file directly from the web site without saving it to your computer first, and you want to make changes and save them, you will need to save the file to a different location using the File -> Save As menu command. If you want to save the program to the default location for NXT program files, this location will be something like the following:
Windows: (Your Documents Folder)/LEGO Creations/MINDSTORMS Projects/Profiles/Default
Macintosh:(User)/Documents/LEGO Creations/MINDSTORMS Projects/Profiles/Default
NXT 2.0 vs. NXT 1.X and Retail vs. Education Versions of the NXT Software
The retail versions of the NXT kits (The original 8527 and the NXT 2.0 8547) come with the NXT software CD. If you lost your CD, you can contact LEGO Technical Support to get a replacement. The NXT 2.0 software can read and use all programs written for NXT 1.X, so if you have the NXT 2.0, you will also be able to load the programs from the NXT 1.X projects and possibly adapt them a similar robot of your own design. The NXT 1.X software cannot in general use programs written for NXT 2.0. You will usually be able to load them and examine them, but some blocks may not display properly. Some very simple NXT 2.0 programs can be downloaded to a 1.X NXT, but in general you will not be able to use them.
The NXT software for the Education version of the NXT (9797) is sold separately here at LEGO Education and contains different help material and building instructions from the retail version of the software, although either version of the software can be used to write programs for either NXT kit. For the NXT 2.0 projects on this site, the LEGO Education NXT-G 2.1 software is required to use any programs that use the color sensor or the Pack-and-Go (.rbtx) format, otherwise the LEGO Education NXT-G 2.0 software will work with most 2.0 programs.
How To Program Mindstorms Ev3
Introduction to Lego and the Mindstorms NXTThe Lego Group is a manufacturer of toys and construction kits which has been around for exactly 50 years as of this writing. In the 1990's, Lego created a line of basic robotics design and programming sets (deemed 'Mindstorms'). These sets generally consist of a processing unit and various Lego pieces for building, motors for moving, and sensors so that the processing unit is able to know what's going on around it. When the Mindstorms series was created, no other company offered a do-it-yourself robotic creation kit, and as of today there is no other product out there that offers a kit like this that includes everything needed to create simple to mildly complex robots.
The latest of these sets is the Mindstorms NXT, which is the second set in the series that allows for complete programming on a personal computer. With a slogan of 'Build and Program Robots that Do what You Want,' the Lego Group advertises that the set includes 577 building pieces and a new 'intelligent brick' with a 32-bit microprocessor and more FLASH memory for storing programs and other files. It also advertises a new ultrasonic sensor and sound sensor, as well as built in rotation sensors for each of its three included motors. At $249.99, this kit may sound pricy, but educational and scientific products with similar capabilities to the components of this set often sell for more.
General Design and Function: Neutral Statements
The first aspect of this product that I noticed, and also one of the more important changes to be aware of compared to past Mindstorms sets, is that everything about this set is larger. The processing unit is about 20% larger and the sensors are on average about twice as large. The motors are about 3 times as large as the previous motors. This makes for larger and more powerful robots (with more sensitive sensors), which can be both good and bad.
In addition, traditional Lego stud-based building has been all but completely done away with. This means that Lego 'Technic' pieces (a system of rods, pegs, axles and gears) will be what robots are made of. As a result, I felt that this system has a tendency to produce vehicular robots rather than robots that rely on stationary structures or mounts. Again, this design decision can be both positive and negative, depending on what types of bots you're thinking of creating.
One last important but not necessarily good or bad design decision is an all new programming language. Though it is still an icon based drag-and-drop language (like the last installment of Mindstorms used), it was reworked from the ground up with more advanced features specifically for the NXT. Dragging icons around to make robots behave differently may be easier to understand for young users, but as an icon-based language it still seems trivial to me (although less so than did the last set's language), and it will seem especially trivial to anyone with other programming experience.
Performance Evaluation: The Good
* Older Lego and Lego Technic pieces are easy to incorporate into the design of robots, and a large assortment of additional sensors is available for purchase from either Lego or other manufacturers, adding large amounts of opportunity for all kinds of robots. In addition, adapters can be purchased so that sensors from the previous Mindstorms set can be used with the NXT.
* All included pieces (electronic and mechanical) were well designed and without defects (showing that a lot of thought went into their design and manufacture).
* Although bulkier, sensors are sturdier and more accurate, and motors are stronger and can sense rotation to the degree. In addition, motors can rotate an axle that goes all the way through or parts that attach to other peg holes on the motor.
* The NXT has Bluetooth for connecting wirelessly to home computers.
* Parallel programming (telling two or more strings of code to run at the same time) is made possible for the first time, and is easy to accomplish with the built in language.
* Third party programming languages like C and Java are available for the NXT, and a new data logging feature offers something advanced users will enjoy.
* An available (but not included) rechargeable battery eliminates the need for 6 AA's every time the NXT runs out of power, and the ability to turn off 'sleep mode' has been added so that programs can run for a long time if you want them to.
Performance Evaluation: The Bad
* The programming language included is useful for learning but not useful for very detailed projects. A large part of this problem could have been avoided if Lego had added some more advanced 'programming blocks.'
* Advertised flash memory is incredibly limited for a device of this size. Even a few megabytes (which is tiny by today's standards) would be enough, but the device offers less than 100 kilobytes for program, sound, and data log storage. To compensate for the lack of space, the software automatically compresses programs, making even very large programs fit, although storing multiple programs is still a problem.
* The set is packaged like traditional Lego sets, meaning storage and sorting of various pieces is a problem (with this type of set, you'll constantly be disassembling and reassembling different robots, and it's necessary to have a place to put the pieces between these times.)
* The models that the set comes with instructions to build are clunky, slow, and somewhat poorly designed (unusual for Lego). The flashy appearance of these models adds to the feeling that Lego is really trying to attract kids to this product and neglecting advanced users, even though the system as a whole has such advanced capabilities.
Conclusion
I recommend the Lego Mindstorms NXT set with reservations. The functionality of the product is much more than what you might expect from a toy manufacturer, but as a 'toy' this product can be a bit child-like. Advanced users will have to find ways around its issues (such as using other programming languages), but for the most part everything you need to make a robot is right in the box.
