No 9-wheeled robot has made it.
Also I believe 3 wheeled robots are 2 for 3.

Well, I'll argue that every single one of six wheel swerve robots have made it to Einstein. Therefore, you should look into six wheeled swerve. All the advantages of traction with the omnidirectional motion of mecanums.
I have not had experience with Treads (of the tank variety) but one of our current mentors came over from Team 1987, Broncobots, and has informed me many many times that treads are simply not worth their trouble. Without a lot of background and prototyping on them, they are difficult to make, repair, and you're probably going to be traversing the field dead slow. Also, for this year, keep in mind that tank treads will be a heavy system.
I have had experience with mecanum wheels and, while not endorsing them over the other, will share what I know about them. They are somewhat difficult to service between matches, unless you bring a full spare wheel or two to just replace the questionable wheel and fix it at your leisure. While it is true that it is an omnidirectional system, it does require a fairly significant amount of driver practice (as compared to a standard drive) because you have to train yourself to utilize the onmidirectional motion availiable.
I, like those before, do submit that you look into a solid six or eight wheel drive system, as there are
many many threads discussing the merits of mecanum vs (6 or 8) wheel drive. It is vastly simpler, lighter than both of the aforementioned drives, and it will be more intuitive for your driver.
