No, it’s not an android-like robot, but rather a big automated machine that sits next to a wall with its 13 cylindrical bins of roasted and raw beans. Six bins hold beans just before roasting.
The tubes are hooked up via a pneumatic mechanism. When someone orders a cup of joe, the Javabot kicks into action sucking enough beans over to the roaster, then the grinder and then into the brewing machine.
You can get a look at (and some coffee from) the Javabot at the Roasting Plant coffee store in New York City.
