Let me translate F.I.R.S.T. for you:
For Inspiration and Recognition of Science and Technology

Now that we got that straight: Some teams out there make thier own robot like our team and probably your team and i can see where the anger is coming from. But you shouldn't look at the bad side look at the good side look at the robot you built (well maybe just the pictures) and say to yourself "I did a great job" feel good about what YOU made not bad about what other teams made.
Different teams have different way of Inspiring thier members you shouldn't be mad at them. That is the way they get inspired to go to colledge and become an engineer!

The competition is like a BONUS the path is what matters.

Mind What You Have Learned, Save You It Can
