I am almost 100% sure they are inside the "main" portion of the robot. However, this is where it gets complicated. Since it seems that they aren't deployable they would have to be in contact with the ground all the time. so in order for the tracks to work they would have to placed perpendicular to the tracks. But to me that can only give you one thing....that would be better mobility on the carpet. Yet somehow with a miracle when the arms fold out they lift up leaving your on your tracks for better grip. Seem reasonable? Otherwise I am lost!
