Fascinating facts about the invention of Wireless Remote Control

Do you know about how wireless remote control come about? Find out from the below interesting facts about this invention!

The first machines to be operated by remote control were used mainly for military purposes.  Radio-controlled motorboats, developed by the German navy, were used to ram enemy ships in WW I.  Radio controlled bombs and other remote control weapons were used in WW II.

Once the wars were over, United States scientists experimented to find nonmilitary uses for the remote control.  In the late 1940’s automatic garage door openers were invented, and in the 1950’s the first TV remote controls were used.

The first TV remote control, called “Lazy Bones,” was developed in 1950 by Zenith Electronics Corporation (then known as Zenith Radio Corporation). Lazy Bones used a cable that ran from the TV set to the viewer. A motor in the TV set operated the tuner through the remote control.  Although customers liked having remote control of their television, they complained that people tripped over the unsightly cable that meandered across the living room floor.

 

In 1956, Zenith’s Dr. Robert Adler suggested using “ultrasonic’s,” that is, high-frequency sound, beyond the range of human hearing. He was assigned to lead a team of engineers to work on the first use of ultrasonic’s technology in the home as a new approach for a remote control.
