GoPiGo for Node.js

The GoPiGo is a delightful and complete robot for the Raspberry Pi that turns your Pi into a fully operating robot. GoPiGo is a mobile robotic platform for the Raspberry Pi developed by Dexter Industries.

Quick start

Before to start you should install Node.js on your RaspberryPi and clone the repo on your local environment. Be sure to have npm installed and then you can proceed installing the package.

Go inside your Node.js application folder and type

$ npm install node-gopigo

Now you can include the module inside your application as usual:

var Gopigo = require('node-gopigo')

At this point you may need to include the GoPiGo base classes:

var Commands = Gopigo.commands
var Robot = Gopigo.robot

Now you can instanciate the GoPiGo, for example:

robot = new Robot({
  minVoltage: 5.5,
  criticalVoltage: 1.2,
  debug: true,
  ultrasonicSensorPin: 15
})

The next step is to add some listeners:

robot.on('init', function onInit(res) {
  if (res) {
    console.log('GoPiGo Ready!')
    /* Now you can do awesome stuff with your GoPiGo */
  } else {
    console.log('Something went wrong during the init.')
  }
})
robot.on('error', function onError(err) {
  console.log('Something went wrong')
  console.log(err)
})
robot.on('free', function onFree() {
  console.log('GoPiGo is free to go')
})
robot.on('halt', function onHalt() {
  console.log('GoPiGo is halted')
})
robot.on('close', function onClose() {
  console.log('GoPiGo is going to sleep')
})
robot.on('reset', function onReset() {
  console.log('GoPiGo is resetting')
})
robot.on('normalVoltage', function onNormalVoltage(voltage) {
  console.log('Voltage is ok ['+voltage+']')
})
robot.on('lowVoltage', function onLowVoltage(voltage) {
  console.log('(!!) Voltage is low ['+voltage+']')
})
robot.on('criticalVoltage', function onCriticalVoltage(voltage) {
  console.log('(!!!) Voltage is critical ['+voltage+']')
})

When you are ready to go you should call the init method

robot.init()

You'll find a more complex example in the "basicTest.js" file under the "tests" folder of the repository.
