Calling all RoboCop/Sci-fi fans in general: this 1924 issue of Science and Invention magazine designed an indestructible “Radio Police Automaton” that would be “well nigh irresistible”:
The “eye lights” and whirling-lead-balls as hands are particularly disturbing:
Such a machine would seem to be exceedingly valuable to disperse mobs, or for war puroposes and even for industrial purposes…. For fighting mobs use is made of tear gas which is stored in a tank under pressure and which alone will quickly disperse a mob if necessary. The arms are provided with rotating discs which carry lead balls on flexible leads. These act as police clubs in action…Bullets do not affect them and if equipped with a twenty to forty H.P. engine, they will be well nigh irresistible.
