Today, the teachers were introduced to the engineering and programming of touch sensors. The touch sensors allowed campers to bump their robots into objects to trigger steps in their robot programs.   Bump-N-Go was the challenging event where campers used their construction and programming skills to complete today's tasks.  The Bump-N-Go design challenge gave the campers the chance to construct a vehicle from a construction card that could strike a barrier, trigger the touch sensor, reverse direction and stop in a box.  The second challenge, Slow as You Go, required at least two motors with coordinated gear and pulley assemblies to make a vehicle go as slow as it could possibly go and still maintain constant motion.  Teams learned a variety of skills all in preparation for the Robot Derby events to be held on Day Five.
