Balancing cube looks more like a star

This art-meets-robot has the grueling task of standing on one foot all day long while other robots get to bend to their heart’s content. It balances on that single point by adjusting its center of gravity with six pendulum-like appendages. To make the system more like the Borg, each of those six modules shares sensor data with the rest and work together to keep the unit upright. Give in to loving the design because resistance is futile.

  1. Interesting, but wouldn’t a gyroscope (or several) be a more elegant (and possibly more robust) solution to this engineering problem?

  2. Now attach a pencil to the tip and make it graph its movements. That’d be interesting.

    Also, how long until it finds the perfect balance? :D
    (I’m kidding, of course.)

  3. I would love to have that displayed in my house (when I buy one.) VERY cool

    If only the future held self-balancing buildings like this ;-)

  4. Wow, great control loop design. When he pushes it, it returns to center with no overshoot. That’s difficult to achieve without serious work.

  5. @ Sam
    Not that difficult, PID controllers don’t need that much tuning to get the overshoot small enough for you not to be able to see it from ~2m away…
    But yes, this is pretty cool.

  6. I want to see it remember what edge/corner it was balancing on and try to right itself after somebody knocks it over.

  7. lol the title is epic agreed

    they have to make little toys like this, like a rubik’s cube that can stand on one point, it would freak people out i want one!

  8. What, no trolls? Careful, could be a trap!

    Seriously though, this is truly impressive. This thing looks more stable than most humans I know standing on one foot!

  9. very impressive!
    This would be a very interesting and ideal application to program with a neural network too

  10. if the corners were roller bearings instead, i wonder if you could push it harder. it looks like it would handle a horizontal push fine but not so much an applied moment.
