Have you ever watched a video and think, yup the end is Soooo much closer then I thought.
BostonDynamics has been releasing video of their various robotics design. Best known for the development of BigDog. Well they posted a video show that their latest creation can now open doors. Yup that is right, open a door. As Scott(writer on the blog) said, give that thing a machine gun and we are all dead.
