    Project N.A.R.A.

    Project N.A.R.A. is an open source Arduino robot project. NARA is a combination of cannibalized components, and some premade things, making the frankenstein that will be.

    LOG:
    June-07: Got my Adafruit driver for my arm, lots of gitHub code changes.
    June-04: Got my DAGU Chassis, motorshield, wired up. Turns out my batteries can't handle the load. NEED MOAR POWA.
    June-03: Got my xBee xplorer and shields in, still waiting for USPS :( 12 day wait FTL.

    Updated... got my Chassis, so NARA can say Hello World!

    But my batteries don't have NEARLY enough juice. Looking to cannibalize a PSU until I can solve my power problem.

    :)

    My batteries wouldnt provide jack for the current this thing needs, so I currently have it hard lined into a junk dell PSU.

    17a works! :roll:

    Current code has FWD, L, R working. I need to re-port my reverse handling from how the Rover 5 handles it, since my motor driver handles negative values as reverse properly instead of a motor.reverse command. I'll probably just re-do the entire section tomorrow. Getting close to end of shift.

    One known issue though: Full throttle currently over volts motors by 50%.

    YAY OVERCLOCKING!
