Hotel guests, this robot is at your service

In "Star Wars," R2-D2 and C-3PO were involved in nothing less than vanquishing an evil empire. In reality, robots are bellhops. Aloft Hotels, which has a location in downtown Detroit, introduced its newest employee Tuesday -- Botlr. The three-foot robot, which looks like R2-D2 sans arms and legs, brings amenities to guests in the hotel lobby or right to their rooms. Moving on wheels, the machine has an enclosed bin that can hold anything from toothpaste to bottled water to whatever else the guest might desire.
