Lazy dog rover, using onion omega2

Motivation

I have a pug called "Zeus", who is super lazy to walk (after 15 mins walk). The purpose of this rover is to drive him when he feels tired of walking

Prototype

Hardware

1. Onion Omega2
2. Onion Omega2 PWM board
3. L298N DC Motor board
4. Lipo battery 3.7v 1000mAh x 2
5. LED x 3
6. 200 Ω resistors x 3
7. 3D printed wheels, rims, and board
8. Battery juice pack 5v 1000mAh, to power Onion Omega2 for stable performance

Pre-requisite

At a minimum, you will need the following tools installed:

1. Git
2. Gulp
3. Bower
4. Node v4.3.1 and npm v2.14.12 (what's available in Onion Omega2)
5. Onion Omega2 or Pi or any other single board computers

Getting started

1. run npm install and bower install
2. run gulp serve to view the controller UI on local machine, don't forget to update websocket server address in app/index.html
3. run gulp build
4. scp both dist and server directory to the micro computer
5. ssh into the micro computer and run node [code_directory]/server/app.js

App flow

1. Server is an node app, that will run both http and websocket server
2. Connect to board wifi (set as ap mode)
3. Load controller UI from browser http://[ip address]:8080
