YES NO

DID YO KNOW?



AlphaDog was initially named "BullDog," but after realizing that the team evoked the image of cute dogs with droopy cheeks and pushed-in faces, Boston Dynamics decided against it.

AlphaDog is so huge it needs to be hoisted by a custom crane to be transported.

HISTORY



Boston Dynamics, led by Marc Raibert, was funded by DARPA and the U.S. Marine Corps. to develop a highly mobile, semi-autonomous legged robot, the Legged Squad Support System (LS3), to help alleviate physical weight on troops. In early 2012, the LS3 prototype underwent its first outdoor exercise, demonstrating the ability to follow a person using its vision system. Next DARPA plans to complete development of key mobile and sensing capabilities to ensure LS3 is able to support dismounted squads of soldiers in the battlefield. The team working on LS3 (also known as AlphaDog) includes engineers and scientists from Boston Dynamics, Bell Helicopter, AAI Corporation, Carnegie Mellon, NASA's Jet Propulsion Laboratory, and Woodward HRT.
