Herbie Photovore Circuit

This is a PCB design I have been working on for the last couple days.
The circuit is for Herbie from Junkbots, Bugbots & bots on wheels by Dave Hrynkiw and Mark W. Tilden.

The intention is to hook it up to some servos that have been modified to work as simple gear motors and make a photovore (light seeking robot) that runs away when it bumps into something. So basically Herbie with some stronger legs and a PCB.
