Yup, Team 60's 2000 bot had a very similar arm back then as well, painted in the very famous yellow and blue... That arm had a basket on the end of it, with a "spine" down the back for hanging on the bar. I seem to remember it being only 2wd however... I'm sure there are pics of it somewhere out there.
Back to this specific robot, you obviously have a lot of manufacturing capability. Welding, sheetmetal, laser/watter cutting... Do you share these capabilities with other teams in the area? (Sorry, I don't know much about your teams' history, or location for that matter.) I'm very jealous!
Nice.
