How do you analyze this sort of question?

Having a good drive base is really where every robot needs to start. TOO many times does our team see rookies with only two wheels motorized, usually direct driving them. Direct driving the wheels is really bad on the motors. Ypu really need to either gear or chain drive every wheel you have.
To give you an idea on a good drivebase, we use 6 wheels, all geared together, using the medium 80tooth gears on the motors, and the 120 tooth gears on the tires. Reason being for 6 wheels, one falls off, you can STILL drive. Not stuck. Along with all the wheels being geared, we run to motors per side of the robot, wired into the same motor port. 2 Motors left, 2 motors right. Alot of pushing power as well! Any robot that tries to play defence against us, just gets pushed out of the way. If you want to see our bot in action, look on youtube, Valley X Robotics, or here,
