Walking robots getting better all the time

Many posts have been made about the new exoskeleton - walking aid that has been developed by Argo Medical Technologies. See the video here. Another development which I found quite amazing was the "Big Dog" quadruped robot developed by Boston Dynamics. See the video here.

Whats amazing about the Big Dog is how it rights itself when the "driver ?" tries to kick it over. Some of these inventions are getting right into the realm of science fiction. But of course, they are real.
