Frightening Robotic Mule

I’m not sure what it is about this robot mule used by the army that makes it so disturbing. Something about the very realistic knees that all go the wrong way. Also I don’t like the way they kick it – although this is apparently to demonstrate its amazing reflexes. Don’t kick the robot mule! The army are encountering some unexpected problems with their growing use of robots to carry out dangerous tasks: like the colonel who put a stop to a robot testing land mines because it was inhumane.
