=RCX or NXT Brick= The RCS or NXT is technically not a computer. It is a microcontroller. A microcontroller is an electronic device that is dedicated to a specific task. The RCX or NXT always does what we tell it to do, although that may not be what we want it to do. The controller can control (talk), sense (listen), and execute instructions, but it cannot think. It follows programming instructions.

=Sensors= Each team may use a maximum of two light sensors, two touch sensors, and three rotation sensors on the robot.
 * **Rotation Sensor:** measures axle rotations, and therefore distance traveled. 360 = one motor rotation
 * **Touch Sensor:** tells the controller when something is pushing the button on the sensor.
 * **Light Sensor**: measures the amount of light reflected back to the sensor, this allows the robot to follow a line.
