Why? It seemed like a good idea at the time ;-)

Honestly, because I am paranoid of getting stuck on those bumps and 12WD seemed like a good way to prevent that from happening.

Would 8WD been enough? Perhaps, but with each new crossing the bump video that gets uploaded to youtube, I grow more convinced that 12WD has its advantages...

Yeah I think a lot of teams will be going with 8wd (we are). The reason 488's robot tipped like that (like many 6wd drive robots will) is because a lot of their weight is distributed in the back. If you can keep your weight balanced correctly, even with 8wd drive, you wouldn't flop like that. (We watched our robot cross the bump on CAD, but haven't gotten the chance to test it in real life yet).

Be aware that with a centered CoG, you will still have a pretty spectacular fall over the bump due to momentum unless you take it somewhat slowly. But not too slowly that you get defended easily. Driving is hard...

8wd shouldn't be high centering diagonally too much. 488's video basically demonstrated you have to be completely sideways to high center.
