He's patting the robot, not pushing him. See? This is all that's wrong with robot-rights activists. They take everything personally and try to manipulate public opinion (whether intentionally or subconsciously, seeing harm where there isn't).

In fact I think the robot is knowingly feigning to get the human punished. I'd totally sue him.
