This Tech Time Warp goes all the way back to July 1977, a couple months after the first Star Wars movie was released. After the movie came out, it seemed that everyone had become robot crazy. The hundreds of robots featured in the movie (a.k.a. droids) like C-3PO and R2-D2 had managed to win hearts.
But, when George Lucas was first creating R2-D2, animatronics experts said it was impossible to have mechanical ‘beings’ who could perform like characters. To give R2-D2 the personality Lucas wanted, he needed to be part remote control and part costume to fully encompass the character. After seeing movies like Star Wars, people got hooked on the idea of creating robots in real life.
