Imagine What This One-Handed, Rubik's Cube-Solving Robot Could Do With a Deck of Cards

At one point in time, it was considered an accomplishment when a robot arm could pick up something as delicate as an egg without crushing it between a pair of pincers. But as researchers from the University of Tokyo's Ishikawa Senoo Lab demonstrate—with the assistance of a high-speed camera monitoring the subtle movements—this agile three-fingered hand can manipulate and reposition Rubik's fiendish puzzle cube with impressive dexterity.

[YouTube video: Rubik's Cube Manipulation Using a High-speed Robot Hand]

Not pictured in this video is an overhead camera system that can capture and process video at an astonishing 500 frames per second. It recreates what your brain is subconsciously doing as you play with a Rubik's Cube in your hands, constantly monitoring the shape, position, angle, and center of gravity of the toy so that the fingers are always positioned properly to provide enough torque to spin the faces of the cube and line up all those colored tiles.

    I just saw this robotic finger [theverge.com] the other day. The Rubik's Cube hand is much less creepy.

      Can they make it vibrate?

        I'm listening. Folks love the vibrate. The women -- and a lot of the men. So I said, do my Presidential Alerts on MAXIMUM VIBRATE. We did that one last week, as everybody knows. And we'll be doing some more. Enjoy!

        And by the way, don't listen to @OfficialMcAfee [twitter.com]. That guy is a SORE LOSER and a NUT JOB! Who wishes it was his message going out over the airwaves. What a creep!!

      Imagine that finger powering the phone down at startup like any useless machine.

      Saw some of Ken Salisbury's work at MIT in the early 1980s. Pretty slow and imprecise (due to high friction in joints and tendons) back then, but clearly the control has improved over the years.

    Rubik's cube are too stiff to operate like that, even oiled.

    This is standard Chinese speed cube. Once you have tried one you will never be able to use a TM Rubik's cube again.

      I haven't used a TM Rubik's cube since 1980-something. Other than my 4x4x4 Revenge my grandmother got me in the late 1980s that I keep as a memento.

    Given that the "hand", cameras and system are designed and trained to specifically deal with a Rubik's Cube, I imagine that replacing the cube with a Deck of Cards would be very disappointing.

    Who knows though, perhaps it would automatically start playing patience without any further programming... because AI?

      AI != Magic, it also isn't true AI, and it won't automatically start playing patience. You'd be doing good, if it could even handle the cards.

    Unless someone programs it to do otherwise.
