“Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles” or what we now know today as remote control. A device most people use daily was not only theorized but developed back in 1893 by Nikola Tesla. Here is his design for a wireless radio-controlled ship, Tesla called them “Teleautomatons”
He demonstrated the system to the Navy by blowing up a target with one of his “Teleautomatons” remotely. But due to the military being in the back pocket of Tesla’s rival “Thomas Edison” they never bought on to the system. Today the military is now moving almost completely in the direction that Tesla envisioned over 100 years ago with their development and use of UCAV unmanned vehicles.
