I think C.G.'s Importan to learn about when building a robot, some of the newer teams might not comprehend or understand the subject matter, unfortunitly, the way the games are played these days, some of these teams will never learn. (some of these teams don't have engineering mentors...)
In 2004. Team 1402 had a robot that was stright up to the line, 5 feet tall, we learned very quickly about C.G. at our preship event. we had five practice matches, we tipped over 3 times in those five matches. We stopped, did our research and redid our frame down to 3 feet tall. a total redesizn later, we had a rookie robot that did not tip, but DID the tipping. (we learned too late that King of the Hill was the stratedgy for the game in 2004.)
our
2005 Robot was built using creativity, but the FIRST question we asked was how we could keep the C.G. low enough where we would be able to cap 4 tetra's at a time without tipping over... (we had to take into consideration the weight of four tetra's).
Because of our team's error in 2004 with our origional design, we never tipped over for the next two years
2006 and Bumpers were totally differen stories...
It's not the fact that i like to see robots tip over, it's just the fact that because robots tip over, either teams adopt to the issue, or learn something the hard way. and improve upon it.
