NXT-Python is a package for controlling a LEGO NXT robot using the Python programming language. It can communicate using either USB or Bluetooth.

NXT-Python for Python 2 is no longer supported.

NXT-Python repository is on Github with a mirror on sourcehut.



Install NXT-Python with pip:

python3 -m pip install --upgrade nxt-python

See installation instructions in the documentation for more informations.

Next steps

You can read the documentation, or start directly with the tutorial.

Upgrading your code

If you used previous version of NXT-Python with Python 2, the documentation includes an migration guide.


There is a mailing list for questions.

NXT-Python repository maintainer is Nicolas Schodet, since 2021-11-06. You can contact him on the mailing list.

You can use the Github issues page to report problems, but please use the mailing list for questions.


  • 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!
  • Elvin Luff for taking over the project after Marcus, making a lot of work for the port to Python 3.
  • (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. ;)
  • Linus Atorf, Samuel Leeman-Munk, melducky, Simon Levy, Steve Castellotti, Paulo Vieira, zonedabone, migpics, TC Wan, jerradgenson, henryacev, Paul Hollensen, and anyone else I forgot for various fixes and additions.
  • Goldsloth for making some useful changes and keeping the tickets moving after the migration to Github.
  • All our users for their interest and support!
