The Lego robot was given clear instructions, but West Alspach and Devon Roberts' contraption had a mind of its own on Wednesday.
The wheeled gadget was supposed to stop after hitting the yellow line taped on the floor, but it would turn, at one point spiraling away and flapping its front part up and down.
"It's refusing to win," said Alspach, a 12-year-old from northeast Minneapolis.
Her partner, Roberts, a 12-year-old from White Bear Lake, was more passionate, shouting in frustration when the robot didn't follow instructions after he'd fiddled with the program on the computer.
Their robot didn't run as planned, but the goal of Best Buy's two-day Geek Squad Academy camp at Minneapolis Central Library wasn't perfection; it was exposure for the 100 campers to the fast-growing tech field.
The Geek Squad Academy camp, in its eighth year, has expanded to 26 cities this year after hitting 20 cities in 2013. It brings together students ages 10 to 18 to explore and experiment with technology. Geek Squad agents and other Best Buy employees staff the camp, and Best Buy absorbs camp costs. The programs are usually free to students selected by the nonprofits to attend.
Minneapolis' camp was backed by several nonprofits including libraries, the YWCA and Urban League, who also recruited the campers. About 20 Best Buy employees staffed the camp's courses, which included 3-D printing, digital music and film.
"To be a part of creating opportunities and empowering their future success is something that I think sits right in the middle of the Geek Squad culture and ethos," said Chris Askew, Best Buy's president of services.
