If you plan to stay in Cupertino's high-tech Aloft Hotel in the near future, don't be surprised if you open your door to a 3-foot-tall robot carrying extra towels or breakfast. See, it's the Starwood property's new butler (officially called A.L.O. Botlr, which is short for "robot butler," of course) programmed to assist the hotel's concierge in catering to your requests. The 100-pound machine comes loaded with a 7-inch tablet screen to interact with guests and staff, as well as 4G and WiFi connections so it can call elevators when it needs a ride. Let's say you pinged front desk to ask for new toiletries -- the staff then just loads the items (as long as they don't exceed 10 pounds) in an empty compartment on top of the robot and inputs your floor and room number on the tablet interface. You'll know Botlr's lurking outside the door when it calls up the room's phone, and instead of a crisp $20 bill, all it asks in return is a tweet with the #meetbotlr hashtag.
