The remote control revolution began in 1898, when inventor Nikola Tesla successfully controlled a 6-foot-long iron-hulled model boat using radio waves. Today, Microbots are the latest remote control marvel. We'll see how, in our technologically-evolved world, pressing a button to get what we want has become commonplace.
