Program Downloads

There are two kinds of program download links you will find on this site. If the program download looks like the following:

LEGO System A/S, DK-7190 Billund, Denmark. Must be 18 years or older to purchase online. LEGO, the LEGO logo, the Minifigure, DUPLO, LEGENDS OF CHIMA, NINJAGO, BIONICLE, MINDSTORMS and MIXELS are trademarks and copyrights of the LEGO Group. ©2020 The LEGO Group. Bring yourself one step closer to integrating WeDo 2.0 into your classroom. Download the software and learn about the solution's system requirements. Download and install all the software and student apps needed to successfully integrate SPIKE Prime, MINDSTORMS EV3, WeDo 2.0 and more into your classroom. Combine this app with the LEGO DC Super Heroes App-Controlled Batmobile (76112), the LEGO City Cargo Train (60198), or the LEGO City Passenger Train (60197) (each sold separately) to operate the motorized engines via Bluetooth controls, or use your imagination and build entirely new creations using LEGO Powered Up components and bring them to life by coding them.

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.

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.

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.

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

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

Download Lego System A/s Driver Installer

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.
