Day Three was the turning point of Robotics Camp 2010 at Murray State. Campers were introduced to sensors, and used the NXT brick to complete challenging tasks from the common pallet of predesigned activities found in the NXT software. "Near Miss" was the name of the challenge that required campers to use the sound sensor to control their robots by clapping their hands or making some other sudden noise. Campers also used both sound sensors and ultrasonic sensors in "Detect Sound" and "Sound Control" activities for their robots to approach a wall, turn 90 degrees, approach another wall, and stop. Next, campers used the ultrasonic sensors on the "Around the Block" challenge activity, where they programmed their robots to detect the wall at each corner of a square track and make 90-degree turns on its own. All campers were excited and are already planning for other challenging events for tomorrow, including the use of touch and light sensors!
