Robot Hand Has No Problem Giving You The Finger

Get your Terminator clichés ready, this robot hand reeks of Skynet. It is designed to function like the human hand, but the main goal is one of robustness. A lot of effort went into making sure this won’t break in the field. Instead of rigid gears, a system of tendons actuates each digit. The pulleys that control these are located in the forearm and each has a spring mechanism that helps to cushion shocks to the apparatus which might damage other grippers. It has bone-crushing power behind the 19 degrees of movement and, as you’ve already guessed, this comes at a pretty steep price tag; topping out around 100,000 Euros. It’s more complicated, and more expensive that jamming grippers, but it’s also far scarier. See for yourself in the silent movie after the break.

  1. I don’t see any reason the cost of the mechanics couldn’t be reduced to the $500-$1000 range. Particularly if it was redesigned to be made from injection molded parts and stamped sheet metal.

    The question is: how much of the sticker price is overkill materials like titanium, how much is small economy of scale fabrication cost, and how much are the control electronics?

    The control electronics have some precision sensors per actuator, and there’s a lot of actuators. The motors themselves could be reduced in cost I’m sure.

    I’m tempted to build one made out of fishing line and corona servos and see how cheap I can go.

  2. Do we really need robots with 4 fingers and a thumb? wouldn’t 2 fingers and a thumb be enough? who really uses there ring and pinky fingers anyways. Its not like these robotos are playing the piano or musical instrument.

    There should be a law where you cant make human looking robots! How will we tell them apart on Judgment Day!!!

  3. Is there a reason hand developers don’t use the same engineering of our hands?

    For example hold your hand up in front of your palm forward and straighten your fingers, now keep your fingers straight and pull the middle finger down to your palm. The rest of the fingers move, I think this is due to how the muscles are attached to the fingers.

    Just a quick thought but do these mechanisms / flaws in how we move our fingers actually help us to grip more efficiently etc

  4. @ Scupham : will I will agree with you that that would probably work in most applications I don’t think that we have the ability to create mechanical “muscles” and “tendons” that can be retrained for finer control as human hands can over time.

    It all depends on what you need your robot to do.

  5. @ caleb & pRoFIT: There’s more to a human being than biological machinery. Unless Robots some how inherit both souls and spirits I think there wouldn’t be be an issue. However if God decided to play a joke on us and actually grant these things to machines, it would interesting to see how a smartphone and a netbook would carry out a debate on the meaning of life, the universe or the merits or demerits of the open source movement. Could you imagine what that would do to a robots psyche to hear two individuales carry on as to wither the next generation of Droids should be windows or linux based? Or the thought that their mind could be wiped and replaced at any given time? I’m glad the tech to treat brains like hard drives hasn’t been realized yet. I wouldn’t trust anyone with that kinda power.

  6. @ pRoFIT

    Make them not able to bleed, don’t give them a pulse and ensure their pinky finger is a bit weird looking, bent and mutated – no wait, those are the aliens David Vincent tried to warn us about…

    Build them like Walter the Wobot and they can make do with three, sorry, thwee fingers.
