KALSABER is an autonomous Light seeking robot that can Track a light source with a hacked servo head, and will proceed to follow it.
Krumlink's Autonomous Light Seeking Advanced BEhavior Robot v1.0
Unfortunately this robot is Currently Disassembled, but I took many pictures, and The circuitry is still working.
Kalsaber uses 4 CDS Cells in a 2 pair configuration that is then fed back through a Conduit that feeds into the robot's Circuity. It has 3 Transistor H Bridges, 1 sensor board, and 1 "Motherboard". It is all custom built circuitry, and the servo has been hacked for easy hook up. The Servo Head has it's H Bridge mounted on it, with the Sensor head on it's Side (look at the pictures). I spent a lot of time trying to get the thing working, then it worked great. I usually just use the Head, since it works nearly perfectly. Unfortunately no Video exists of it operating, but it worked great :)
All point to point wiring xD
