Who patented a way to control vehicles remotely using radio waves?

• A. Guglielmo Marconi
• B. Niels Bohr
• C. Thomas Edison
• D. Nikola Tesla

Answer: (D)

Remote control of vehicles using radio waves was first patented by Nikola Tesla. He demonstrated a device that could be steered from a distance using radio signals and described a method and apparatus for controlling mechanisms with wireless communication in his patent work. This specific achievement—a patent for remotely controlling a vehicle by radio—links him directly to the concept.

Guglielmo Marconi made foundational advances in wireless radio communication, but his work focused on transmitting signals, not on patenting remote-control systems for vehicles. Niels Bohr is known for his work in quantum physics and atomic structure, not remote-control technology. Thomas Edison contributed many electrical inventions, but he did not patent a radio-based remote-control method for vehicles.
