American Internet giant Google Inc. on Friday confirmed that it had completed the acquisition of Boston Dynamics. Boston Dynamics is an engineering company that has designed mobile research robots for the Pentagon.

Terms of the deal, however, remained unknown. 

According to a report by the New York Times, Boston Dynamics has gained an international reputation for its machines BigDog, Cheetah, WildCat and Atlas.

Boston Dynamics is the eight robotics company that Google has acquired in the last half-year. The deal is a clear indication that Google is intent on building a new class of autonomous systems that might do anything from warehouse work to package delivery and even elder care, the report said. 

Boston Dynamics was founded in 1992 by Marc Raibert, a former professor at the Massachusetts Institute of Technology. It has not sold robots commercially, NY Times said. Boston Dynamics' previous clients include Pentagon's Defense Advanced Research Projects Agency (DARPA). It also did consulting work for Sony Corp. on consumer robots like the Aibo robotic dog, the report said.
