Students from across the globe descended on the valley last weekend for the annual Canadian International Rover Challenge. The competition pits teams of university students against each other in a friendly competition, building and operating the best space rover. There were 17 teams at this year’s event including one from Poland. The machines and teams are put through a series of trials testing the machines. The weekend culminates with the Rover Olympics where the teams go head to head in a fun competition. The Tug of War had some decisive victories.
