Robocol

Javascript library for interacting with FTC robots

Add to your project: npm install robocol

Current Features:

• [x] Connect To Robot
• [x] Parse returned telemetry data
• [x] Run basic commands including initializing and starting opmodes
• [x] Send gamepad data
• [ ] Support All Commands (possibility add generic callback?)
• [ ] Work in browser (Not planned, no current way to send UDP packets)

Examples

Log all telemetry data from robot

import { Robot, RobotEvent } from "robocol";

const robot = new Robot();
robot.connect();
robot.on(RobotEvent.TELEMETRY, console.log);

Send gamepad data to robot

import { GamepadMessage, Robot } from "robocol";

const allReleased = {
  left_stick_x: 0,
  left_stick_y: 0,
  right_stick_x: 0,
  right_stick_y: 0,
  dpad_up: false,
  dpad_down: false,
  dpad_left: false,
  dpad_right: false,
  a: false,
  b: false,
  x: false,
  y: false,
  guide: false,
  start: false,
  back: false,
  left_bumper: false,
  right_bumper: false,
  left_stick_button: false,
  right_stick_button: false,
  left_trigger: 0,
  right_trigger: 0,
  updatedAt: 0,
};
const aPressed = { ...allReleased, a: true };

const robot = new Robot();
robot.connect();

// Start pressing A every second after initial 0.5 second delay
setTimeout(() => {
  setInterval(() => {
    robot.send(new GamepadMessage(0, aPressed, 1));
  }, 1000);
}, 500);

// Start releasing A every second in order to alternate
setInterval(() => {
  robot.send(new GamepadMessage(0, allReleased, 1));
}, 1000);

Init and run the first opmode found

import { CommandMessage, Robot, RobotCommand, RobotEvent } from "robocol";

const robot = new Robot();
robot.connect();

robot.on(RobotEvent.OPMODES_LIST, (list) => {
  const firstName = list[0].name;
  robot.send(
    new CommandMessage(
      RobotCommand.CMD_INIT_OP_MODE,
      0,
      false,
      Date.now(),
      firstName
    )
  );
  setTimeout(() => {
    robot.send(
      new CommandMessage(
        RobotCommand.CMD_RUN_OP_MODE,
        0,
        false,
        Date.now(),
        firstName
      )
    );
  }, 500);
});

Remote FTC

Intro

This is meant to be a project to help teams that have team members quanatined but still wish to be able to host driver practice remotely. It allows a driver to control the robot remotely, from another location.

How do I use it?

1. Have the driver either visit this hosted copy or host your own
2. Have the proxy computer download the .exe from the releases section of github or build your own NOTE: this computer must both be able to access the internet and connect to the robot at the same time. While making this project, we did this by connecting with ethernet to the internet, and connecting with wifi to the robot, though other options may exist.
3. Have the driver click open the control tab and the proxy open the proxy tab
4. Have the driver enter the room code that is being shown on the proxy's screen and hit submit
5. Select an opmode, initialize, and hit start
6. While driving, use a video calling app for the driver to see the robot. This project does not have a camera view of the robot.
