PORTLAND -- Some very talented teenagers are set to put on a show at the Portland Memorial Coliseum this weekend.

They're part of a competitive robotics competition, and on Friday they showed off some of what they built.

Some robots climb, others throw Frisbees, and they're all the result of a lot of hard work.

It helps us learn how to use all the equipment we've used in the shop it really helps out with team bonding and it's a really good way to get out in the community too, said teacher Eric Groshoff of Spokane's West Valley High School.

Sixty different teams from around the region will be competing this weekend, and the winner goes on to the finals in St. Louis.

The event is free to the public.
