I think that even if you can get your robot to track another's goal, you still have to have a way to determine which side of the opposing robot you are facing. You may be locked onto their goal, but their robot might be facing yours, and you might just end up dumping all of your cells onto their robot, instead of into the goal. Even when you are behind the other robot, if you are both moving at similar speeds, it is going to be hard to keep tracking and following them. I also haven't put much thought into shooting, but it seems like it would be hard to do.
also, i was trying to find out where we can buy the "regolith", and found Glasteel's site.
http://www.awci.org/buyersguide/file...el_MPC2007.pdf one of these might be worth looking into, but they dont have very many distributors or manufacturers. and it seems 100% necessary to have a lot of time to practice driving this year.
