'Grounds are just magical'

So sayeth the EE. After being shown the data sheet for the h bridge, reworking a common ground to the arduino, the motors spring to life!

A quick bench test and the robot hurtled itself onto the floor to the end of its usb cable tether.

I've coded up some simple menus and added some way point code a la ardupilot. Can't wait to see if I can seek a point autonomously.
