You can always check the websites of teams but that isn't always accurate and some teams don't provide alot of info. Watch practice rounds, make up a team to record matches and info on each robot, and also go to all the pits. Before we have a match we go to each pit and just act like we're walking around and ask ?s. Sometimes you can find out their weaknesses or even if their robot is working correctly. The majority of the time the other team doesn't even know you're up against them until after. It's quite funny. Then you can report back to your pit and stratagize even better.
