The Computation Engine has been designed to sense its environment in numerous ways. It has several systems for the detection of light rays invisible to the human eye (known among the scientific community as infrared). These systems are located on what I colloquially call the "eye board." One infrared sensor on the board is used to sense the amplitude and duty cycle of the infrared beacons that are positioned around the playing field for navigational purposes. The other infrared sensor is used to detect the flash that signals the commencement of game play.

Not only can the Computation Engine sense invisible light rays, but it also has multitudinous other sensors enabling it to approximate its location within the playing field. Four disguised switches on the front and rear allow the device to sense walls and other objects along the perimeter of the playing field. Sensors embedded underneath the belly of the device allow it to navigate based on coloured pathways of tape lining the course.

Above you will find details of these sensory systems. These include diagrams of the circuitry, design calculations, and a representation of what the engine sees when it scans for the invisible light. Guard these secrets carefully friend; they are essential to the future construction of similarly wondrous devices.
