LEGO League tournament is Saturday in Richland

Participants in the sixth annual First LEGO League Tri-Cities Regional Tournament will face a "Food Factor Challenge."

Competing teams, made up of kids ages 9 to 14, will solve real-world problems using the robots they built and programmed with LEGO Mindstorms technology. This year, teams will be judged on how their robot demonstrates innovative food safety solutions.

Opening ceremonies begin at 12:30 p.m. Saturday, followed by the competition and an awards ceremony. Six teams will advance to the state tournament.

The event is at Chief Joseph Middle School, 504 Wilson St., Richland.
