    The Omni


    A one piece model featuring three tendons that should bend the tip in any direction by pulling on the rings.

    Absolutly no intended purpose other than to just see if it works. :rolleyes:

    Looks like a fun concept!

    I wonder if would be strong enough to grip something...

    I doubt a single 'digit' would grip anything :laughing:

    The idea for The Omni sort of came from THE ROBOT WORKING MODEL HAND. It would be entirely possible to make a three fingered hand with one 'tendon' per digit using the same technique, but that has function and has been done before.

    The Omni is pretty much a useless and possibly functionable model :confused

    Sir, I think you just unwittingly explained the mechanics of a tentacle! :D
    it's a pretty amazing concept, being able to make a self contained "thing" move in any direction you want, I can imagine a series of these with tiny servos at the end of each module making a robotic tentacle, would be amazingly useful in search and rescue operations such as searching through rubble or inside caves with tiny entrances :p

    have you thought of using nitinol?.. its a memory wire that can bend to a shape when a current is passed through it, rather than using servos.

    But memory wire gets hot when working....

    [​IMG] - heat is why memory wire works.

    Personally for actuators, I favour air muscles :)

    fair enough:)... i have seen a little remote control plane that used nitinol, how hot does it get?

    It's not the absolute temperature that is important, it is the temperature of the wire relative to the encasing plastic. WSF will be able to deal with a much hotter wire that, say, any of coloured detail.
