Just in time for Star Wars: Episode VII The Force Awakens, a Japanese outfit named Aqua developed (and licensed) an R2D2 that is fully functioning--meaning, it holds enough cold beer to keep Honey Boo-Boo's clan well-rested on tattered La-z-boy chairs for about 20 minutes or so. Then the over-worked robot needs a refill.
The price has yet to be disclosed, but if it's anything like cosplay replicas, you're looking at about $15,000. That's a lot of money to keep a 12 pack in a fridge.
Unless you understand Japanese, ignore the talking and skip to the one-minute mark and watch the slowest robot made on earth take its time creeping toward the speaker. In fact, the person recording the awkward stage presence proved to be more interesting with random jolts and shaky hands.
I'd say that this is a dud of a product. Cool looking, sure, but that's really it.
