In summary, FIRST Illinois website says it best...
"FTC is about teaching students the value of hard work, innovation, and creativity. It goes beyond the competition by teaching teenagers about the importance of working together, sharing ideas, and treating each other with respect and dignity.
When a student joins an FTC team, they join a global community of students who are interested in using technology to build a better world tomorrow. There are over 20,000 students from around the globe who design and build robots to compete against one another in competition. They compete locally to earn their way to the annual FTC World Championship!"
