Jankboard

build https://good-labs.github.io/greater-good-affirmation/assets/images/badge.svg

This repository hosts the last version of the source code for the Jankboard worked on by me.

Jankboard is the fully custom control interface designed in-house by Team 1280 for the 2024 season of the FIRST Robotics Competition. The FIRST Robotics Competition is an international high-school robotics competition which runs annually. Teams spend six weeks designing, prototyping, and building a robot to compete in each year's game. The goals for each game vary by year.

Though this is a Team 1280 project, it's hosted on my GitHub account as I wrote the vast majority of the code and retain rights to it via the license. A small portion of this codebase was contributed by @quantum9innovation. I've released it as free and open source software under the GPL v3, as permitted by Team 1280's policies for post-competition software stewardship.

The Jankboard is a fully functional control interface designed to be used with our 2024 robot. It is intended to work alongside the FRC Game Tools application, which is required by the rules to handle processing robot control inputs. The Jankboard is a dashboard which receives the telemetry data from the robot and displays it for the driver. It also processes it to provide useful features. It replaces the standard "Shuffleboard" dashboard program provided by FIRST, and has a much cleaner and purpose-built UI.

Jankboard is built with Tauri, which is a framework for building desktop application with Rust and webviews. Unlike Electron, it leverages the platforms built-in web technologies (Chromium on Windows, WebKit on Linux and MacOS) to avoid shipping a massive bloated binary with a bundled browser. Our (my) choice of web framework is Svelte, a modern framework with a compiler. To interface with and collect telemetry from the robot, a Rust backend implements the low-level networking and communication details and streams the received data back to the frontend UI. As soon as new data is received, the frontend is updated immediately. We found that this provided more than enough speed for our purposes, since the robot sends new telemetry at a rate of 10 Hz. We chose this tech stack because building beautiful and functional UIs is easiest with the Web, and it allowed us to rapidly build the application during our 6-week development period.

Installation guide

We recommend installing the latest stable release binaries from our release page, if you're just looking to run the Jankboard. Alternatively, if you can't find release binaries for your system, follow the directions below in the For developers section to build it from source. We will periodically update the releases with new builds when we come out with stable versions, and we follow semantic versioning.

A brief note on the name "Jankboard"

The name "Jankboard" comes from Team 1280's original attempt at creating a custom dashboard. Though it looked and functioned superficially similar to Jankboard, it was not designed with maintainability in mind and became exceptionally difficult to extend and develop as the codebase became bloated. Jankboard is a version redesigned from the ground up with the goal of easy maintainability and richer features. It contains both a completely rewritten frontend and backend, which have been improved in almost every possible way.

For developers

If you would like to contribute to Jankboard, there's only a few simple steps to get the development build up and running.

Prerequisites

  • Rust and cargo. Check the Rust docs for more information. We recommend you install Rust using rustup. Keep in mind that this is ONLY necessary for development, release binaries do not require Rust.
  • pnpm, for installing dependencies and the vite development server.
  • NodeJS

Installation steps

  1. Clone the repository. The client directory contains the vast majority of the source code for the desktop app, while the splash-screen directory contains the source code for the splash screen displayed before the app loads. You don't have to touch anything in splash-screen unless you want to modify it, in which case check the README in splash-screen for more information.
  2. cd into the client folder. The configuration files and package.json, This is where stuff like package.json and configuration files for our various tooling are housed. The client/src-tauri directory contains the Rust source code and cargo configuration files for the backend that interfaces with the robot via Network Tables.
  3. Run pnpm install to install dependencies.
  4. To run the desktop app in developer mode (with automatic hot stateful reload and other useful features like error reporting), make sure you're in the client directory and run pnpm run tauri dev. This will install and build the Rust dependencies via cargo and initialize the vite development server for the frontend. Note that since this is basically just running the vite development server and then connecting the Tauri webview to it, there may be slightly inconsistent behavior in dev mode versus production mode.
  5. To create a production binary, run pnpm run tauri build. Tauri cross-compilation is still in beta, so you should build targeting the same OS you're currently running. For example, create Windows builds from Windows. Check the Tauri docs for more information. We also have some Github Actions set up to automatically compile a production build for all platforms, but this is expensive (uses over 30 minutes of our quota), and should only be used for publishing new major releases.

Troubleshooting common issues

  • If you're experiencing issues with TypeScript type checking or dependency resolution, try opening your editor directly in the client directory so it picks up the tsconfig.json and uses the project's own TypeScript language server.
  • If you don't have access to a development environment that supports running standalone executables (eg. Github Codespaces), you can try running pnpm run dev instead of pnpm run tauri dev, which will open a development server at localhost:5173 with the frontend running in the web. However, app behavior may be inconsistent and you will not get any features from the Rust backend.

Licensing

This project is released as free software under the terms of the GNU General Public License. What that entails for a developer seeking to use portions of this codebase, or even the entirety of the codebase, for their own purposes, is the following:

You are given the freedom (rights) to copy, modify, and distribute this software, in its entirety or just a portion of it, with or without modification, provided you meet the following requirements:

  • If you do make modifications to the software, you are required to release the source code of your modifications, also under the terms of the GPL v3, if you are planning to distribute the software. However, this is not required if you are not planning to distribute it. See below.
  • You may modify or use it however you'd like personally or internally (within an organization, like your robotics team), without releasing your changes or code under the GPL. This means that if you make a custom dashboard based on this code for your own robotics team, you do not have to release the code as long as you are not planning to distribute your custom dashboard to other robotics teams or publish it publicly on the internet. If you do intend to distribute it, then you must release the modified source under the terms of the GPL v3.
    • We think that this is fair - if you intend to keep an internal private tool, we should not stop you from doing so. However, if you intend to publish your tool or share it with others, then you should also publish or share the source code for the benefit of other developers and robotics teams, as we have done here.

See the full license text of the GPL if you need further clarification. The above is simply an explanation of the license, if any conflicts between the above text and the license text arise, then the original license text takes precedence.
