Crazy I tell you, just crazy! Apparently our European brethren are already familiar with automated video rental stores, where human interaction is null and void. During my typical afternoon surfing at work I noticed an ad for RentalRobots and it looks like it’s coming to the US.
Essentially you buy all the components you need to run a video store. Then, just open the doors and make sure the power stays on, the rest is done for you. However, if you want to offer some level of human interaction there is an optional web interface for customer support.
