AlphaDog is the new robot in town from Boston Dynamics. Think Big Dog on steroids.

AlphaDog (official name: LS3 (Legged Squad Support System) is designed to assist soldiers in carrying heavy loads (up to 400 lbs of gear) over rough terrain, IEEE Spectrum blogger Erico Guizzo reports.

AlphaDog is getting close to something that can be used in the field, using GPS navigation and computer vision to follow soldiers while carrying their gear over any kind of terrain, IEEE Spectrum blogger Evan Ackerman notes. DARPA and the U.S. Marines will begin to put the robot through its paces next year.
