Based on every horror/sci-fi movie I've ever seen, squishing an actual fleshy human brain into a robot would make it unstoppable. Sooner or later, I'm sure someone is going try it for real. Until they do, what's almost as good is letting a robot borrow an actual fleshy human brain to help it balance and complete tasks requiring sensing and dexterity. It's like teleoperation, except the user's brain and body are controlling the robot directly, from inside a haptic suit. HERMES is a disaster response robot from MIT based on the Cheetah Robot, developed by Professor Sangbae Kim and his group at the MIT Biomimetic Robotics Lab.
