[Jamie Price] directed us to this photostream of the build for Bar2D2. Though it isn’t the first bartender bot we’ve covered. It very well could be the best executed. Bar2D2 can travel around the party dispensing bottles of beer, shots, and even cans. The construction looks fantastic. You can follow along in the photostream from the very beginning. It is currently radio controlled and can party for about 8 hours per charge. The next planned upgrade is a system that allows you to choose a mixed drink from a database and Bar2D2 will mix it up.
[H.P. Friedrichs] sent in his Sanfordyne project a while back, but It took me a while to appreciate the effort he put in. (Partly because the write up is so long – but thorough) Grab some of your favorite caffeine supplement and take your time reading over the details. Most of the parts were scavenged, and he mechanically etched the pc board with a dremel tool.
