Which inventor is credited with an early remote control patent for vehicles using radio waves?

• A. Marconi
• B. Bell
• C. Nikola Tesla
• D. Edison

Answer: (C)

The main idea here is who first showed that a vehicle could be controlled remotely using radio waves. Nikola Tesla was the pioneer in this area, demonstrating and patenting a system in 1898 that let a device aboard a vehicle respond to signals sent from a distance. He built a remote-controlled boat and outlined in his patent how radio signals could be received and converted into mechanical actions, like steering or stopping. This work established the concept of wireless remote control for vehicles, a foundational step for later RC and drone technologies.

While Marconi is celebrated for advancing wireless radio communication itself, his contributions came from transmitting signals rather than controlling a vehicle from afar. Bell and Edison focused on other inventions and did not introduce an early remote-control patent for vehicles using radio waves.
