Big Dog is, the most herrible robot I have saw, beening developed by Boston Dynamics.
It walk and run as humans. It can easily walk in many poor conditions like icy road or ramp. Although it is hit by humans, it can keep being in a balance.
I think it will be realized very soon that the robots will join the wars in the future. Robots will not only show their skills in Sci-Fi movies, but also show them in the real world.
