i noticed a lot of people are saying that four-wheel drive is the way to go. how do you do it? we tried four-wheel in FIRST last year, and it was a *disaster*! we couldn't turn at all until we covered the rear wheels with slippery plastic to decrease traction, and even then turning nearly burned out the drill motors. in the end, the only way to get decent manuverability was to run each wheel off a seperate motor. what did we do wrong?
From the sound of things, I'd bet you had two problems: your gear ratio was too high, and the treads on your wheels were too grippy. Those two things together can cause big problems for any robot. However, if you pick the right tires and the right gear ratios, 4WD can be many times better than 2WD for pushing power, especially.
