we should get all the robots that have omni wheels and make a big gallery of them, that would look cool..

I'm sure that Dave's answer above is the main reason that the omni wheels are on the back, but there is probably another. 177's robot was meant to have an arm for hanging and grabbing the 2X ball. If the robot had actaully ever been driven while holding a ball out in front, most of the robot's weight would have been over the front wheels. It would have been harder to control and very easy to push sideways if the front wheels had been omni-wheels. This is why our '98 and '00 robots had front wheel drive and rear casters enve though it is generally easier to control a robot with rear wheel drive and front casters (Buzz frequently builds their robots this way when they are picking up balls from the floor).
