Japanese YouTuber Ron Tajima likes to build robots. Not necessarily the kind of robots that are going to revolutionize manufacturing as we know it, but the kind that will turn from a beer can into a cute little creature or from a Roomba into a baby cradle. This isn't to say that Ron's robots aren't special, just that they're a little quirky. And there's nothing wrong with that.

  • Now your beer can come to you. Too bad it's empty.

  • Rock-a-bye baby, on the treetop / When the Roomba moves, the cradle will rock.

  • It's a birthday cake that cleans up its own crumbs. Ingenious!

  • Why clean when you can surf?

  • If there's one thing Pac-Man likes more than pac-dots, it's dust.

  • These bug-shaped nanorobots are hacked to scare Ron's son.
