Had to speed much of the morning on a conference call where I was only needed if there was issues for my team. We had no issues so I had 5 hours of listening to other people work out issues. While setting here I found a few things to play with. Here is a simple quick robot build.
There is an official boe-bot arduino shield but no need for one if you already have the boe-bot. My boe-bot came from a project my son did in high school. They did some basic stamp/robotics programming and this was the left over frame. The stamp and other parts have been scavenged for other projects.
Paralax bot-bot chassie.
Need the frame, 2 servo's and the roller wheel in the front.
Most any model will work
Arduino proto shield
Not needed if you want to hardware your project.
