Man builds machine to push phone buttons from half a world away (video)

Sean Hollister

If your ambition was to travel the world, and your job to push the buttons of three cellphones located in South Korea, you might go insane. That seems to be what happened to Mok Young Bak, at least, when he invented the crazy contraption depicted in the video above. Called the Caduceus, it's a telepresence machine that does just one thing -- it controls every single button on each of those three phones with a series of servo motors and actuator cables, and moves a pendulum-like webcam so he can clearly see each screen from wherever he happens to be. That way, he can enjoy tourism while leaving his livelihood within reach, at least so long as concerned neighbors don't assume the terrible din is, say, a killer robot assembly line, and insist that police investigate.
