The advantage of four legs

Shortly after SoftBank acquired his company last October, Marc Raibert of Boston Dynamics confessed, "I happen to believe that robotics will be bigger than the Internet." Many sociologists regard the Internet as the single biggest societal invention since the dawn of the printing press in 1440. To fully understand Raibert's point of view, one needs to analyze his zoo of robots which are best know for their awe-striking gait, balance and agility. The newest creation to walk out of Boston Dynamic's lab is SpotMini, the latest evolution of mechanical canines. Big Dog, Spot's unnerving ancestor, first came to public view in 2009 and has racked up quite a YouTube following with more than six and one half million views.
