The 2010 Challenge: Design & build a self-powered ball-shooter that can travel from the start area to the shooting area and shoot a tennis ball at the goals without human intervention. The power source of the ball-shooter may be mechanical, gravity, pneumatic, hydraulic or any combination of these. Friday 11 May saw the DSS Technology Olympiad take place in the Grade 8 class. The machines were judged on number of balls shot, aesthetics, maneuverability and efficiency.
