A hotel chain in Silicon Valley has unveiled Botlr, the world's first robot butler, which will work as a bellhop shuttling items between the hotel lobby and guests' rooms.

Aloft Hotels in Cupertino, California, is situated opposite Apple in Silicon Valley and is known for its high tech hospitality, which includes Apple TV in-room services and interactive software known as "Cool Concierge" which looks up any information the guest might need.

The three-foot tall robot was made by robotics start-up Savioke, which recently created the SaviOne robot as a delivery robot for the services and care industry.
