Probably about 95% of the people who surf the forums here participate in a International Robotics competition which is designed by a group called
FIRST.
Each year, FIRST designs two seperate games in which teams from across the US and as far away as the UK, or Brazil compete in.
FIRST has two different competitions, one for Junior High School students using the LEGO Mindstorms kit called
FIRST LEGO LEAGUE, and the second competition they oversee is the
FIRST ROBOTICS COMPETITION which is the high school version of their game.
The two competitions are seperate from each other, but teams from each competition come together at the end of their season in Atlanta to compete at a Championship event at the Georgia Dome.
This forum is for mainly (but not limited to) participants in the High School version of the game.
For an even better explanation of FIRST and what it is all about, see the
FIRST Wiki article on FIRST.
Oh, and did I mention that the competiton is very addicting? lol
