Some high school students designed and built robots in just six weeks as part of a robotics competition. The competition kicked off the Smoky Mountain Regionals on Friday.
The robots are complex; they can throw frisbees and scale pyramids.
"Once you get that finished product of a robot that can shoot a frisbee, that makes a goal. We were making goals from 40 feet back-- after that, you just get a feeling of accomplishment," said Elijah Stiles.
Hundreds of high school students are taking part in the competition, including 13 Knoxville area teams.
The competition continues Saturday at the Knoxville Convention Center, and the winning teams will advance to the international finals in St. Louis.
