TECHNOLOGY

Light-Tracking Wheel

The basic control scheme for this device is the same as that intended for the turret control.  It rotates the wheel in the direction of the photosensor with the higher reading.  The movement is unfortunately very twitchy, and aside from the obvious reasons, it may be due to the large light source.

Sunlight-Tracking System

This system tracks sunlight in a similar fashion (by analyzing the difference between two separately located sensors).  It addresses the issue of having an incredibly large light source (the sun) is by filtering the light through a “microhole”.

Fuzzy Logic Light Tracker

This is a device that accurately aims at light albeit in a narrow range with an ingenious light-blocking vane between the input sensors to exaggerate the light difference.
