The art of teaching new robots old tricks flourishes in Japan with the Yaskawa Bushido Project, which pits Iaijutsu swordsmanship master and quintuple Guinness World Record holder Isao Machii against a mechanical arm in a contest of technique and endurance. After using motion capture to teach the machine Machii's cutting techniques, the Yaskawa Electric Company captured a series of swordsmanship tests with man and robot side-by-side in the video below to see if a computer program could trump years of training and certified excellence.


Whether or not a series of controlled tests can really hold a candle to Machii's instincts, improvisation, and creativity is up for debate. What's isn't open to discussion, however, is the awesomeness of watching a robot cut a pea pod in half with a samurai sword.
