Robotic Hand Made Of Wires Is Flexible Enough To Rotate Meditation Balls

Baoding balls are two metal balls that are rotated over and over again in one hand for meditation, exercise or rehab purposes. A lot of dexterity and focus and strength is necessary to pull of the rotation. Not everyone can do it! This robotic arm controlled by wires can though. Look at those fake flexible fingers move.

To be clear, in advanced exercises the Baoding balls shouldn't be touching but I'll cut the robot arm some slack since it's a beginner. The robotic hand is impressive because it does such a good job of replicating the nimbleness and flexibility of our human hands.

It's pretty fascinating how the hand was made, the researchers first created a dummy hand and then tracked and measured six different poses of the hand necessary to rotate the meditation balls so they could design a specific transmission system that would control the prosthetic.

    I've always wondered why we haven't been able to mimic the mechanical construction of a human hand yet.
    We have all the blueprints, we have working models. Why is it so hard to replicate. It's just a dynamic mechanism. It's a complicated one, sure, but with today's technology and materials it should be pretty straight forward.
    I think this is the first time I've seen a working, lifelike robotic hand.

      The mechanism *might* (that is a gross understatement) by simple enough to replicate these days, and we *might* know enough about how it works. But having a hand means nothing if you can't control it properly, that is the real problem, actually teaching a hand how to do its thing. Humans take what, 3, maybe 4 years of near constant learning to become average with their hands.

        Control is an easily solvable problem. Robotics are very advanced now (I work in the field) and the things we can do with software is pretty amazing. If we can code a simulation of a hand then we can code the movements of a real one.

        A full feedback loop with senors and skin etc... is harder but again it's a hardware problem not a software one. The control is easy (as shown above). You can just pull a few cables. In fact, that's all our body does, it expands and contracts a few muscles and pulls on the bones and tendons.

          You really just described the hardware problem as to why we don't have proper hands yet and dismissed it as a "hardware problem" and no control is not easy. I completely agree, we have amazing stuff right now, stuff I never thought we could have in my life time. But this is still a difficult problem to solve, but nowhere near as difficult as it used to be.

          I love the world I live in, despite its flaws.

    Am i the only one thinking of dangling my nuts in that hand. :)

      Not anymore you aren't! Thanks for the laugh haha
