This is the first video of the Rover 2-0.
To install and configure the web cam I used the instruction from this blog www.lucadentella.it.
It exactly what I was looking for and it's really clear and complete.
All project files are here.
There are some improvements in the arduino Yun sketch and in the web server html page.
I also added some values to adjust the wheels' speed.
In the next post I'm going to add webcam pant/tilt.
