My first thought is, no, not because of the movies and tv shows depicting robots causing mayhem of various sides of the scale, but how are the robots controlled and decisions made?

If by AI, well you can only imagine how much error they will have based on their programming.

Remote controlled, like they have been before, results in quick reaction delays.

Either or can be a scare tactic to get the upper hand and/or control a situation, while still having draw backs of general control use.
