The Treads have to be built right that is the main thing, you have to take all variables into concern. We built a friction drive Tread system and geared it to have the strength of 10 Bears.
The Turn issue you guys talked about earlier is not a problem at all, we actually turn better then previously built wheeled robots.
The best part of this is the fact that you get in a pushing battle with someone who has treads......I'm afraid you won't have much luck

. I have already myself tried stopping our robot and it didn't turn out well.
We did have a center of gravity issue, but we resolved it by relocating the battery. If all goes well we didn't even build a hanging mechanism, we either shall try to get in other peoples way or the best part just driving up onto the box.
Have Fun out there
