BATON ROUGE, LA (WAFB) - Middle and high school kids from across the country showed off their high-tech underwater robots Saturday.
Teams were battling it out on LSU's campus, taking the robots through an underwater course.
All of the machines had to be put together with low-cost materials like PVC pipe.
Teams qualified for Saturday's national championship through several smaller competitions.
The winners were crowned Saturday night at the LSU Carl Maddox Fieldhouse.
