Re: What does it take 6WD/8WD to be successful?
Its more than just hardware... it's also in the software.

Put a gyro on your robot and you can make sure that it drives straight, even when you've got unequal drag on each side... or when you're being bumped. A gyro can respond more quickly and accurately than a driver.

We've also found that using seperate control sticks for Forward/Reverse and Left/Right can help tracking. That way, when using "arcade" style driving (rather than tank style, where you control each side or the robot with a seperate stick) when you want to go straight forward you just lift your thumb off the "turning" stick, and you will always get a perfectly straight forward/reverse input to the robot. When you want to stay still and turn, you take your thumb off the forward/reverse, and all you get is turn. Sure... you can tune your deadbands and all that, but this is what we've found to work best.
