Why Google bought robot-maker Boston Dynamics

Google has boughtBoston Dynamics, the maker of futuristic military-grade robots including the galloping "WildCat" and the Sandflea, which can jump more than nine metres into the air.

Boston Dynamics is the eighth robotics company Googlehas purchasedin the past six months.

CBC business commentator Kevin O'Leary, chair of O'Leary Funds, saidMonday that the strategymakes sense, given the majority of "smart and new money going to startups today" is targetingsensor technology.

"These robots are basically a bundle of sensors," he added. "What Google is doing here is simply buying a company that's extremely advanced at writing software to interface with sensors."

Google confirmed the purchaseto the New York Times late last week.
