Robofest
Robofest is a competition for 5-12 graders. It is similar to FIRST Lego League (FLL), but while FLL limits the student's robots to Lego Mindstorms robots, Robofest allows the student to use any robotics system, or even custom electronics, in some of the events. In addition, FLL students are required to use parts manufactured by Lego, preventing the use of such aids as string or glue. Robofest was founded by Computer Science Professor Dr. Chan-Jin "CJ" Chung and is sponsored by Lawrence Technological University.
Robofest is also held internationally, in countries including Canada, Mexico, China, Hong Kong and South Korea. Teams who win their regional event are welcome to participate at the worldwide tournament held in Michigan.
