RobotPy web-based low fidelity FRC robot simulation package

Project description

pynetworktables2js

A cross platform library that forwards NetworkTables key/values over a Websocket, so that you can easily write a Driver Station Dashboard for your robot in HTML5 + JavaScript.

This library does not provide a full dashboard solution, but is intended to provide the necessary plumbing for one to create one with only knowledge of HTML/Javascript. Because the communications layer uses NetworkTables, you can connect to all FRC languages (C++, Java, LabVIEW, Python).

Documentation

Documentation can be found at http://pynetworktables2js.readthedocs.org/

Installation

Make sure to install python 2 or 3 on your computer, and on Windows you can execute:

py -m pip install pynetworktables2js

On Linux/OSX you can execute:

pip install pynetworktables2js

Why make an HTML/Javascript dashboard?

TL;DR: It’s simpler.

pynetworktables2js lowers the barrier of entry for teams that want an additional way to tune/control their robot with a minimal amount of programming.

Lots of students and mentors know how to create simple web pages to display content, and there’s lots of resources out there for creating dynamic content for webpages that use javascript. There is a lot of visually appealing content that others have created using web technologies – why not leverage those resources to make something cool to control your robot?

Usage

Go to the ‘example’ directory distributed with pynetworktables2js, and run:

python server.py --robot 127.0.0.1

If you want to try this out with your current robot, you can do:

python server.py --robot roborio-XXX.local

If you navigate your browser (I recommend Chrome) to http://127.0.0.1:8888, all of the current NetworkTables values will be shown as they change.

One way of testing this out is use FIRST’s TableViewer application (you can launch it using the “Outline Viewer” WPILib menu item in Eclipse), and start it in server mode.

Feel free to copy the example directory to create your own customized dashboard. Just add your custom files to the www directory.

Contributing new changes

pynetworktables2js is intended to be a project that all members of the FIRST community can quickly and easily contribute to. If you find a bug, or have an idea that you think others can use:

  1. Fork this git repository to your github account

  2. Create your feature branch (git checkout -b my-new-feature)

  3. Commit your changes (git commit -am 'Add some feature')

  4. Push to the branch (git push -u origin my-new-feature)

  5. Create new Pull Request on github

One place in particular I would love to see contributions is in adding useful javascript functions/objects that make creating dashboards even easier!

Authors

Leon Tan of FRC Team 1418 did the initial research/work to get this working, and created an initial working prototype for Team 1418’s 2015 Dashboard, which was instrumental to winning an Innovation In Control award at the 2015 Greater DC Regional.

Dustin Spicuzza cleaned stuff up, rewrote things, added more functionality, wrote documentation, and packaged it so other teams could use it.
