Re: 2 motor drive VS 4 motor drive
I've seen robots do it reasonably well. So it is sufficient.
I used the handy-dandy JVN design calculator to check, though. Without the extra motor, you increase the load on the remaining motor and halve your torque output without changing maximum speed. It still works, it just doesn't push as well.
That's good when you don't have to, or can't, push other robots. In 2009, additional torque was pretty much wasted on the slick floor; you'd just spin out the wheels. The weight of the motors was better used elsewhere that year.

Reason: I fixed the design calculator
