One day robot

In all my time building robots I've never built a line follower and thought it was about time. I figured the electronics from a Snappy type robot would work as a line follower, so I decided to give it a try.  I built up another board, re-configuring the light sensors to look at the floor this time.  Then I designed and printed a new chassis.  This is the result...

The software turned out to be incredibly simple, I just added about eight lines of code to the light seeking code running Snappy, and abracadabra the robot follows lines...

Snappy got his name from one of the Smurfs - I'll have to go through the list again and find another one for this guy.
