Have you been following the work of Boston Dynamics?
They're the guys building the disturbingly life-like robots. Not human looking, but human acting. Quite creepy to watch in action.
They produced a "mule" for military use a couple of years ago, which was rejected for being too noisy.
Then they posted footage on YouTube of a humanoid "bot" running, climbing, jumping & even doing back flips.
Their latest offering's a dog sized, 4 legged creature. The clip below shows it being stumped by a closed door -until a second one arrives, fitted with an arm that rises from it's back, opens the door, stands back to let the first one through, then follows it.
Amazing, but very weird. They're completely autononous & self contained -no remote control, no trailing wires, making decisions & acting on them by themselves.
The legs bending in the wrong direction are definitely creepy though!
