Notorious B.O.T. by Tom Wilga

My robots name is Notorious B.O.T.. It's base is in the shape 
of an octagon. Its main function is for robotic sumo
competitions. It pushes and shoves the other opponent(s) out 
of a 6' in diameter ring. It runs on 12 (car battery) which
is off-board. It as rated at 20A but now is at 2A because of 
competition rules! The parts used are a couple of BIG Lego
tires, 2 car fan motors, some sheet metal, plywood, good ol' 
duct tape, pipe clamps. I had quite a few problems while
building this robot. The first one was trying not to get the 
robot over the size limit. It has to be 1 foot x 1 foot x 1
foot. It's a little small, but I am plannig on building a 
bigger robot for the next season. The next problem I had was
going within the weight limit. It has to be 10lbs or less. 
So far, it is 8.5lbs. From there, I just has problemswith
wiring and getting the wiring right aswell as the resistors. 
The approximate time to build was 2.5 months. The cost was a
measley 50$! It also has a ramp at the front (not shown in pics) 
which will be pulled down by an 18V motor I picked up at
Radio Shack.
