There's a high-tech competition playing out at the Knoxville Convention Center this weekend.
More than 50 schools from the U.S. and Canada are in town for the Smoky Mountains Regional Robotics Competition.
It's called "rebound rumble" because teams compete with their robots to score as many baskets as possible.
The event is less about robotics and more about learning the value of math and science and real life lessons.
"They've got a six week build cycle to put this robot together. So they've got a time schedule, a money schedule, they got an engineering schedule, they use collaboration," said Michael Wehrenberg, a judge of the competition. "The whole environment is really trying to get the students to think and start realizing what it's like to work in the business world."
The competition wraps up Saturday.
