The robot used for robot formation is currently a zumo bot, that we bought from polulu's website.
We chose the zumo bot because it is small at an affordable price. We use an arduino uno, mounted on the zumo shield which is on a 10x10 chassis.
The robot has two micro metal gearmotors, used in conjunction with wheels and treads. We use 4 AA batteries as our power-source.
