Using a Nao, a $15,000 robot; a treadmill (for moving the robot forward); a head-mounted display (to see what the robot sees); Kinect (for tracking his movements); and two Wiimotes (to move the robot's hands), Valtrop is able to pat a cat with surprising accuracy and gentleness (except for where he accidentally hits the cat in the face)."
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
