  • Longer distances
  • Longer battery life (hours vs. minutes)

iPad App


Hackability


  • Has WebUI left over from factory testing
    • Username: AC13 Password: AC13
    • Contains a hidden page that lets you dump the firmware
    • Once you dump the firmware you can view the test code
    • After translating chinese you can figure out how to control it
    • Factory test controls happen over HTTP
  • Has custom binary protocol over TCP sockets
    • Command messages start with MO_O
    • Camera frame messages start with MO_V
    • Frames are 0 padded and have set lengths
    • Blowfish encryption used on sensitive messages

Web UI


Library


var rover = require('rover');

var client = rover.createClient();

client.forward(function(){
  client.right(function(){
    // etc.
  });
});

Use async


var rover = require('rover');
var async = require('async');

var client = rover.createClient();

async.series([
  client.forward.bind(client),
  client.right.bind(client)
], function(){
  console.log('done!');
});
