There's plenty of knowledgable people in FIRST that don't frequent ChiefDelphi. Coming here doesn't in and of itself make us smarter than those who don't
"Robotics" is a very broad subject. For our purposes, fundraising, PR, Animation, and Leadership are all as big a part of robotics as CAD, Programming, Electronics, Mechanics, etc. You don't need to have a strong knowledge of the latter to be involved and useful. The more time you spend around it, the more you'll pickup though.
Good luck.
