Hi,it’s me again.I was looking at other ways to move my robot,and I came across the Lynxmotion Tri-Track Chassis Kit (no electronics).I need to know what the parts are that I need to add to it. Sorry for another stupid question of mine.I just would like to know some of my choices. I want to use of course,the arduino uno (once again, the new one) is what I want to use. 
You would need a 12V Battery, charger, charging cable and motor controller (and some additional wiring). To that, you would add the sensors, pan/tilt etc.
