Finally an update on my newest line following robot. This robot has 4x4 drive and has a CMUcam and an IR rangefinder mounted on board. A spotlight and a servo assist the CMUcam. All the processing is done using the Axon microcontroller.
I wrote up my own code for controlling the CMUcam from the Axon, and I will post source code in about a week.
Here is a quick video I made of the robot tracking a red box.
