Kuka on keksinyt radio-ohjauksen?
In 1898, at an exhibition at Madison Square Garden, Nikola Tesla demonstrated a small unmanned boat that used a coherer based radio control. In a bit of showmanship, Tesla entertained the audience to make it seem that the boat could apparently obey commands from the audience but it, was in fact, controlled by Tesla interpreting the verbal requests and sending appropriate frequencies to tuned circuits in the boat. Tesla was granted a US patent on this invention on July 1, 1898. In 1903, the Spanish engineer Leonardo Torres y Quevedo presented the ""Telekino"" at the Paris Academy of Science, and was granted a patent in France, Spain, Great Britain and the United States. In 1904, "Bat", a Windermere steam launch, was controlled using experimental radio control by its inventor, [Jack Kitchen].
