555 Timer Photovore Robot
This is a simple robot that I made for my cousin, it only uses 2 LDRs, 2 geared motors, and a 555 timer IC.
I reused a Tamiya Tank tread kit and gearbox for locomotion. All powered by 4 AA batteries. The batteries, IC, and switch are all housed in an Altoids tin.
Not much more to say about this robot (Sorry OddBot)
Schematic I found from the internet.
There's not much to see on the inside because i DeadBugged the 555 Timer.
EDIT: As of July 25, 2012 this robot no longer belongs to me. It has been shipped off to Chicago to give company to my cousin.
