The AlphaDog Proto is a lab prototype for the Legged Squad Support System, a robot being developed by Boston Dynamics with funding from DARPA and the US Marine Corps. When fully developed the system will carry 400 lbs of payload on 20-mile missions in rough terrain. The first version of the complete robot will be completed in 2012. This video shows early results from the control development process. In this video the robot is powered remotely. AlphaDog is designed to be over 10x quieter than BigDog.
