Several of our team members also participate in FTC on Team 9785 Cronos. The team qualified for the Georgia FIRST FTC State Championship today. Due to several students being on that team and our mentors being at the competition, we didn't have practice today. Cronos finished 5th in their division and was the 4th Alliance Captain. They lost in the first round but we are proud of them making further than either of our FTC teams have ever made it in our history.
