Raspberry Pi BigTrak with Robot ARM

A short video of my Raspberry Pi controlled BigTrak with a Robot ARM attached to it. This has been rebuilt around a Raspberry Pi Model A after a loose power wire shorted out and killed my original Model B! This time around everything is soldered onto an AdaFruit PiPlate with proper click together connectors for the external connections (Motors, Power, LED). Still needs a bit of a tidy up.. Trying to decide if I can squeeze the USB hub inside as well.
