After six weeks of rigorous preparation, three Michigan robotics teams -- from the Bloomfield Hills International Academy, the Utica Community Schools and Kettering University (a team from North Oakland and Macomb schools) -- triumphed as the winning alliance in the third annual FIRST Robotics Detroit Regional Competition. A total of 33 teams came from across Michigan and Ohio for two days to drive, bump, navigate and shoot balls with their custom robots on the playing field in the Matthaei Building at Wayne State University. Michigan teams have won the national championship in each of the last four years.
