BLACKSBURG, Va. The stands are full in Blacksburg High School as more than 3,000 high school students compete in teams from Virginia, Maryland and D.C.

Robots from three different teams work together to create an alliance.
Two alliances, red and blue, face each other in a 2-and-a-half-minute match. The robots have to complete different tasks for points.

Competition will continue Sunday.
