A pure Python implementation of NetworkTables, used for robot communications in the FIRST Robotics Competition.

Project description

RobotPy NetworkTables Project

This is a pure python implementation of the NetworkTables protocol, derived from the wpilib ntcore C++ implementation. In FRC, the NetworkTables protocol is used to pass non-Driver Station data to and from the robot across the network.

This implementation is intended to be compatible with python 3.5 and later. All commits to the repository are automatically tested on all supported python versions using github actions.


NetworkTables is a protocol used for robot communication in the FIRST Robotics Competition, and can be used to talk to SmartDashboard/SFX. It does not have any security, and should never be used on untrusted networks.


If you require support for Python 2.7, use pynetworktables 2018.2.0


For usage, detailed installation information, and other notes, please see our documentation at

Don’t understand this NetworkTables thing? Check out our basic overview of NetworkTables.


On the RoboRIO, you don’t install this directly, but use the RobotPy installer to install it on your RoboRIO, or it is installed by pip as part of the pyfrc setup process.

On something like a coprocessor, driver station, or laptop, make sure pip is installed, connect to the internet, and install like so:

pip install pynetworktables


The RobotPy project has a mailing list that you can send emails to for support: Keep in mind that the maintainers of RobotPy projects are also members of FRC Teams and do this in their free time.

If you find a bug, please file a bug report using github
