Engineering and Robotics Battle Bots & Tops: Campers learn to design and build their own motorized battle cars and other vehicles. Using principles of simple and complex machines, gearing, and mechanical advantage, students will try to flip, push, or smash their opponent's battle vehicles. Students learn the use of mechanical lifts, drills, ramps and more to disable or overcome other bots. Students may outgrow their love of LEGO® bricks (don't count on it), but this insight into physics will stay with them forever.
