More than 500 middle school students from across Connecticut will descend on Shelton High School this weekend to compete in a statewide robotics tournament. The Connecticut FIRST Lego League State Robotics Championship event will take place Sunday, Dec. 7 from 9 a.m.-4 p.m. The event is free and open to the public. The robotics team members will have competed successfully at regional qualifying events during the past six weeks. Connecticut has more than 200 registered teams, and the top 50 teams will be coming to Shelton. Students from four Shelton teams have qualified for the state tournament \u2014 the Perry Hill Predators, Perry Hill Brainiacs, Shelton Intermediate Robotic Revolution, and Shelton Intermediate Dominators. The top overall winner at the Sunday competition will represent Connecticut at the FLL World Festival in St. Louis next April. Design, build and program robots In the competition, students design, build and program LEGO-based robots to perform tasks. Using LEGO parts, motors and controllers, students race against the clock to score points on a field of challenges designed for robotic competition. Additionally, students also must research innovative educational strategies and make presentations to judges as a part of the overall team score.
