NXT-Python is a package for controlling a LEGO NXT robot using the Python programming language. It can communicate using either USB or Bluetooth. It is based on Marcus Wanner's work ending in 2013, which in turn is based on NXT_Python, where releases halted in May 2007.

• Python 3.x (Currently developed using Python 3.5.1)
• Bluetooth Comunications:
  • Linux/Windows: PyBluez
  • Mac: LightBlue
• USB Communications:
  • PyUSB Fantom Communications:
  • Pyfantom

1. Go and grab the latest version from the releases page - the master branch is usually too unstable to use
2. Untar/unzip source package
3. Navigate to the package directory, and run python setup.py install
4. import nxt in your program and get going!

This is a quick overview, detailed instructions can be found on the wiki page.

This version is part of the 3.x series of releases. Programs written for series 1.x or 2.x will not run properly or at all using this version, due API-breaking changes. v3.x is functionally similar to v2.x, however is written for Python3 releases and as such will not behave correctly running code designed for Python2! If you wish to run an older program, older versions can be downloaded from the releases page.

Since the 3.x and 2.x series use the same API, in most cases code can be automatically converted. Python2 and Python3 include a built in 2to3 script which will automatically modify the program. However, there is no converter between the 1.x and 2.x series - it's very unlikely you will come across a 1.x program these days. Read the documentation and do it manually!

• Doug Lau for writing NXT_Python, our starting point.
• rhn for creating what would become v2, making lots of smaller changes, and reviewing tons of code.
• Marcus Wanner for maintaining NXT-Python up to v2.2.2, his work has been amazing!
• mindsensors.com (esp. Ryan Kneip) for helping out with the code for a lot of their sensors, expanding the sensors covered by the type checking database, and providing hardware for testing.
• HiTechnic for providing identification information for their sensors. I note that they have now included this information in their website. ;)
