The most important part of the robot, regardless of the game, is the drivetrain.

MAKE SURE THE BATTERY DOES NOT FALL OUT

Design things to be much stronger than you think they need to be. When something goes wrong (your robot falls off 2 second level of the pyramid), and your robot doesn't break, it's very impressive to watch

Don't get too attached to an idea. Your first idea is never the best, and 99.99% of the time, there's somebody who can help you make it better. (as JVN says, design is all about iteration.)

At a competition, doing well is not an excuse for not testing the robot. This is why you don't tell your drivers the team's rank until its time for alliance selection.
