My weekend project: an Arduino, Raspberry Pi & Node.js robot

Yes I know, I'll get more buzzwords when I my JavaScript creates Cloud Synergy - but after I Pivot.




I've been spending my wee few hours a week designing, tinkering and finally building my little robotics platform. I've had ideas brewing for a while but haven't had enough time outside of work to start hacking.

It all started when I first saw Rick Waldron's Johnny Five framework for Node.js.
Sensors are asynchronous, so, ya, a node.js robot framework makes sense. A few months later I started sketching designs, reading up on firmata and buying my arduino & Pi.

Before the what & why, here's the basic BOM:
1 Arduino Uno R3 running firmata1 original Raspberry Pi with Raspbian, Node.js & 4gb of storage1 Magicians chassis1 SN754410NE Quad Half H-Bridge to drive the motors1 dual-output mobile battery backA custom mount for the Pi & some custom USB cabling for power Why Raspberry Pi The main controller is a Rpi. It turns 2 small motors by delegating instru…
