TED crowd favorite: Boston Dynamics' dog-like robot

Boston Dynamics' robots may terrify a lot of people, but you couldn't tell that from the reception its creation got at TED. A huge throng gathered around CEO Marc Raibert and SpotMini after the two got done on stage Tuesday. People wanted to take selfies and even pet the quadruped robot.

When can I get one: There's no word on pricing, but Boston Dynamics is still targeting businesses and the military rather than consumers. There's a better chance one will some day deliver you a package than that it will live in your house. (The company has started testing package delivery to employee's homes in Boston and is talking with companies that do local deliveries.)
