Qualifying Robot Matches
See Robot Game Rules on "The Competition" Page
Each team will receive 4 qualifying matches on Saturday.
At the end of these matches, the team’s lowest score will be dropped and the addition of their 3 highest scores will determine their Robot Performance Score! Teams will be ranked 1 to 16 based on that score.
There is also an award for Most Consistent, which is the lowest standard deviation of those 3 top scores (teams must have an average score >200 to be eligable - we included the udder-ly awesome math below for your enjoyment)
Ambassador Award
Ambassador Award
Teams can apply to be chosen as the FIRST WI FLL Ambassador!.
What does a FIRST Ambassador do?: Ambassador Teams help spread the FIRST ® word and grow the program, which in and of itself is an accomplishment. Ambassador teams share their knowledge and experience by mentoring teams who need assistance. This could involve attending other teams’ meetings, talking with them over social media or digital communication methods, and/or any support a team could provide. The team that embodies the FIRST spirit this season and is willing to be a bridge for other teams entering the program will be recognized state-wide as the FIRST ambassador.
