Around 5 PM on Fridays, many of us here at Willow Garage start thinking that a cold one would taste pretty good. However, we often have a few loose ends to tie up before the weekend begins in earnest. In this situation we've often thought about how perfect it would be to have the robot autonomously deliver beer. The goal of Willow Garage's third summer hackathon was to make this dream a reality. The idea of the hackathon is to start hacking Monday morning and demo on Friday afternoon.
