I bought this... http://www.robotshop.com/productinfo.aspx?pc=RB-Rbo-89&lang=en-US
And its being a pain. I configured the wireless xBee, had it all plugged in, I uploaded the code on the website to the rover, and uploaded a code that sends a 'w' then delays and stops then repeats on the uno. So when i plug everything in nothing happens, but when i plug the usb in to the rover, the rover starts moving and runs the code on the uno, which is totally wireless. It doesnt make any sense. The uno is no plugged into the computer so i dont understand why the rover only works when its plugged into usb??
****I just plugged the usb into a charger for just power and it still does the same, so its a power issue, for some reason if there isnt enough power it doesnt recieve the signal, in know its enough power to move the motors, but when i unplug the usb a light flashes and it stops moving
