Long vs. Wide Drivebase

[ProgramLuke]

Is your team going with a wide or a long drivebase?

Long
Pros:
Not Tippy
Cons
Longer base takes up more room on bridge

Wide
Pros:
Takes up less room on bridge

Cons:
Tippy

Anything else?

tippy tippy tippy. If you're going over the bump, or even over the bridge, you almost always have a large chance of tipping.

well you can only pick up 3 balls at most....

If you want to be picked for elims then go wide. No long robot will get on that bridge with two other robots and balance.

Three wides will fit with 11inches of overhang. If one of those is long you are never balancing.

What if you want to be one of the picking teams in elims? There might be some other considerations too....

[bearbot]

you could have bots one wide then long then another wide and to balance it out you shift the long bot

I vote square bot. My team disagrees but I like it.

Actually, what I really want is a bot that's tiny but still shoots. That would make me happy on the inside.

Use holonomic or mecanum, you'll have both.

What if the long-bot turns 90* after it's on the bridge?

It'll have to be perfectly balanced, and turning with 2 other robots on the bridge will be hard if not impossible.

The transverse (wide) bot does have its advantages. For one, you have a greater pick up area. Even though you can only carry 3 balls, it'll still be easier if you don't have to worry about being perfectly aligned, you can just run over the balls and grab them. Also, there is a greater chance for tipping, but if you keep a LOW center of gravity, you'll be fine. My team had a transverse bot in 06 and we had no problems, and that was with a giant ramp that you had to climb at the end. It shouldn't be a problem. But hey, it's up to team decisions, you should have your chassis fit the rest of your robot's functionality.

I think you are overestimating how tippy the bridge is. You can be pretty offset and the bridge will still stay "balanced"

Everyone seems to be overestimating this. I predict it will be harder to get two robots on one bridge than it will be to balance the bridge when they are on it.

But the bridges are pretty slanted; that might make it tricky for a 'wide' one to climb and climb over them.
