Highschool teams from around the world converged in Atlanta at the Georgia Dome for the FIRST world championships this weekend. Teams had to grab “moon rocks” and toss them into trailers being towed by competitors. Some of the most effective teams could dump 20 volley-ball sized “rocks” into the 6ft tall trailers in seconds. FIRST runs robotics competitions for kids in high school and younger (Lego league). It’s a great opportunity to mentor for people involved in engineering companies. One challenge of the competition was finding the “moon rocks”, which Walmart stopped selling after the building season was well under way.
