Diego Fierro, 13, hopes to be a mechanical engineer someday. And thanks to a LEGO Robotics: Space Challenge camp at the University of babyÖ±²¥app Boulder, Diego took one step closer to that dream this week. “I’ve never built anything with LEGO Mindstorms before,†Diego explained, as he programmed the robot’s next move. “It’s cool because it gives me an idea of how a machine works, how every piece is important and has a job.â€
