FTC Dashboard Replay

FTC Dashboard provides telemetry and monitoring tools for FTC robots during operation with the following features:

• Live telemetry with plots and field graphics
• Live configuration variables
• Camera streaming
• Limited op mode controls and gamepad support
  • Note: Gamepad support is volatile due to unstable browser APIs
• Custom dashboard layouts
• Telemetry CSV export

Check out our online documentation.

Installation

Basic

1. Open build.dependencies.gradle

2. In the repositories section, add maven { url = 'https://maven.brott.dev/' }

3. In the dependencies section, add implementation 'com.acmerobotics.dashboard:dashboard:0.4.15'

   Please see GitHub releases page for the latest version number

4. If you’re using OpenRC or have non-standard SDK dependencies, add the following exclusion:

   implementation('com.acmerobotics.dashboard:dashboard:0.4.15') {
     exclude group: 'org.firstinspires.ftc'
   }
   

Development

Installation

1. Install Node.js

   • Note: Node.js 16+ is required for builds to work on M1 MacBooks
   • Current Node version used in gradle builds can be found in FtcDashboard/build.gradle
   • Node version is 18.12.1 as of time of writing

2. Install Yarn

   • Not explicitly required and provides little advantage over modern npm (as of the time of writing)
   • Further instructions will however reference yarn over npm for historical reasons

3. Browser FTC Dashboard client is located in FtcDashboard/dash

4. Run yarn (alternatively npm install) to install dependencies

   • This only need be done once

5. Optionally, specify the server IP address through the environment variable VITE_REACT_APP_HOST

   • Details on Vite's environment variables can be found here

   • Default IPs:

     • Android Phone: 192.168.49.1
     • Control Hub: 192.168.43.1

6. Run yarn dev (alternatively npm run dev) to start the development server

   • This will start a development server on http://localhost:3000 by default
   • Navigate to this address in your browser to view the dashboard client
   • The development server will automatically reload when changes are made to the source code

Mock server

To test without an FTC app, run the mock server located at DashboardCore/src/test/java/com/acmerobotics/dashboard/TestServer.java.

• Mock server is a simple Java server hosting mock FTC op modes
• A test sample op mode can be found at TestSineWaveOpMode.java
• Test op modes are registered in TestOpModeManager.java

Basic Architecture

Java Server

Dashboard's server is split into two packages, DashboardCore and FtcDashboard

• Dashboard Core
  • A standalone library that can be used to create a dashboard server for any Java application
• FtcDashboard
  • A wrapper around DashboardCore that provides relevant tooling and hooks for FTC teams
  • Contains the API FTC teams will access and manipulate through their own code
  • This package also contains the browser client source

Browser Client

Primary interface as a web-client acessible to the end-user through a web browser

• Located in FtcDashboard/dash
• Installation and run instructions mentioned above
• TypeScript + React application
• Vite for builds
• Web Socket connection to the dashboard server

Relevant files

• Dashboard.tsx
  • Primary functional entrypoint
• LayoutPreset.tsx
  • Contains preset layouts
• views/
  • Contains the various views that can be displayed on the dashboard
    • Graphs
    • Telemetry
    • Gamepad
    • etc
• store/
  • Contains shared state management logic
    • Web Socket connection
    • Gamepad state management
    • Storage middleware
    • etc
• Views subscribe to websocket updates via the Redux store
  • Basic example can be found in the TelemetryView component
