Gugo writes "German based company FESTO has develop a bionic arm that uses muscle emulation,(video included) with a product called 'fluidic muscle.' It works like a normal animal-human muscle but moved by air inside. This new type of prosthetic offers rapid response, small size, simple assembly and ease of control. On their website they show the range of fluidic muscles with a car race simulator."

Would this break arms in a wrestling contest? And how does it stack up in such a contest against the jet-engine assisted are, recently featured on the fronpage?

About the natural covering...

Warning, if you are at work, please do NOT follow this link, but if you are at a safe place where you can see a bit of porn, this is a link to a lifelike silicone doll: www.realdoll.com [realdoll.com] .

Not that I am trying to post porn on Slashdot, but a link to what kind of technology is available to make a lifelike human form suitable for prostheses.

I can imagine the silicone covering fluidic muscles which would look very lifelike, even warm to the touch, and feel just like real muscles. The fluid bladder comprising the muscle belly could be made in any shape so that the aesthetics of how the muscle appears as it is flexed could be tailored to match the natural muscle.

One could have the appearance of a bodybuilder, or a fashion model, or whatever.

I can not see a fluidic muscle being very strong, but in the absence of natural muscle, anything is more useful than nothing. It will get your hand up to your mouth to feed yourself, comb your hair, or do your buttons, although I doubt it would be useful for heavier work.

The bicep-tricep pair would operate as opposing muscle/fluid reservoir so that in order to bend the arm, fluid is pumped from one bladder to the other. The forearm could be full of small opposing bladders to control the fingers, all run from a small microcontroller and power source. From the outside, it would appear just as muscle appears, even bulging when flexed just like real muscle.

It sounds like a great fun thing to work on, knowing that I would be creating something someone actually needs.

I'm not surprised. I realized long ago that robotics engineers are experts at missing the awesome potential of their creations. For instance, we commonly see high-tech robot demonstrations in which a robot dances, but not one of these engineers thinks of making them dance the robot? Sure it's impressive to see a robot waltz smoothly, but it seems almost unconscionable to not end the demonstration by dropping a nice breakbeat and having the robot pop-lock it's way off-stage.

An improvement? (1)

Zatchmort (1091857) | more than 7 years ago | (#20334219)

In the video, the arm still looks clumsy. Its movements are similar to the ones in the movie Short Circuit. Sure, this looks a little more realistic (or it would if there was some sort of skin simulation), but without sophisticated software to enable more lifelike movements, I don't see how this is any better than what we already had.

Re:An improvement? (1)

As this tech progresses and matures and becomes more cost-effective, I look forward to seeing it replace the usual rigid prosthetic limbs that so many people sport nowadays. The more realistic, useful, and durable the better, and this festo research is definitely privileging those factors.

tgatliff (311583) | more than 7 years ago | (#20334381)

It does not look like its percision is very good, or at least no where near what a pneumatic approach can give you. I mean in the video it bearly could write huge letters. Obviously design evolution could help in this, but unlike a biological system, it will not get better percision with more use. Personally, I think that Pneumatic systems are the best for arms because their speed, accuracy, repeatablility, and sheer power are just amazing. I will admit that they are not without their problems as well, though...

Any idea why... (1)

markov_chain (202465) | more than 7 years ago | (#20334473)

this sort of ligament-based actuation has not developed more? The principle of having a small deflecting force among the muscle fibers producing a large sum force at the joint seems very elegant. Are the alternatives (pneumatic, hydraulic, servo) that much better? Maybe this design will turn out to be far more energy efficient than those.

Re:Any idea why... (2, Informative)

Anonymous Coward | more than 7 years ago | (#20334959)

This actually is a hydraulic device. There are a lot of reasons linear actuators aren't more commonly used in robotic applications: they lack the force-to-weight ratio to be effective when hooked up like a real muscle; they draw a lot of current; they're heavy; they have to be always energized. The fluidic/hydraulic or pneumatic systems allow you to displace the power generator from the power application, so you relieve the power-to-weight issue (at least for fixed installations-if you want a human to carry the hydraulic pump that runs the arm, then there are issues). The fluidic system has the further advantage of being naturally damped. Pneumatic systems are essentially springs in which the rest length of the spring is set by air pressure. This makes the very bouncy & somewhat hard to control. Either fluid or air powered systems rely on valves and flow to change lengths & forces, and this has historically been harder to control than a servo motor position.

Festo pneumatic acuators for robotics - good stuff (4, Informative)

Animats (122034) | more than 7 years ago | (#20334503)

Festo does good work. They're an industrial automation company, and they do demos like this for promotional purposes. Check out their videos on YouTube.

The innovation here is not "fluidic muscles". It's their piezoelectric proportional valves. It's been possible for years to do precision control of pneumatics. Twenty years ago, "Pneumatic Valves, Inc." in Palo Alto was doing control like that. But older proportional valves were big and expensive, with a voice coil actuator on the end of a spool valve. Festo has miniaturized the technology with their piezoelectric valves [patentstorm.us] .

Pneumatic systems have traditionally been either force actuators or devices driven to a limit stop. Fine position control was the domain of hydraulics. This is changing. For pneumatic systems, if the valves can be brought close to the actuator, the valves are fast, position sensors are used, and the control system is well designed, the system becomes quite controllable. That's what Festo is demonstrating here.

You can also do some things with pneumatics you can't do well with electrical drive, such as create springs with variable spring constants. Muscles can be usefully modeled as spring-damper systems, where the spring constant, zero point, and damping constant are all controllable. This can be emulated with electrical actuators, but emulating a spring in software requires high-powered actuators and loses energy. Legged running work needs something like a variable spring, and pneumatics are currently the closest thing to muscles available.

Doc Ruby (173196) | more than 7 years ago | (#20335573)

What about aerogels doped with metals that contract electromagnetically?

One valuable feature of muscles is their power:weight ratio. Aerogels are extremely light - now something like only 20% lighter than air. And they have lots of other valuable engineering properties, including high strength (up to their critical collapse point). And they're cheap to manufacture (in their current form).

Why go with mere "air muscles", when aerogels could offer a much more highly structured, functional material?

Couldn't get to the video, but it sounds like the Shadow Air Muscle [shadowrobot.com] - they sell the individual 'muscles' and have a whole hand using the same stuff.


They were building a very ambitious Biped Walker [shadow.org.uk] out of wood a while back but it seems to have been scrapped now.

According to This Article [thomasnet.com] it's built like this:

The basic concept involves the wrapping of a watertight, flexible hose with non-elastic fibers arranged in a rhomboidal fashion.
Does sound similar to the Shadow Muscle [shadowrobot.com] :

The Air Muscle consists of a rubber tube covered in tough plastic netting which shortens in length like a human muscle when inflated with compressed air at low pressure.

> They were building a very ambitious Biped Walker out of wood We moved to building hands [shadowrobot.com] a while ago, on the grounds that a robot with legs can walk around, but a robot with hands can actually do something.

A little redundant, unless you're a creationist.

Some years back, Festo started wandering round our website every week. Then they came out with their muscles - which, of course, they had to give a different name... Now, they've produced something we did, ooh, 6 years ago? Still, the marketing is pretty slick. Anyway, we've got hands [shadowrobot.com] to build...

We are using one of these... (1)

We have been using one of these "muscle" actuators as a clutch actuator in our racing car for about half a year now. So the muscle itself is not a new product. So far we did not have any problems with it or any other component of the car's pneumatic system which were provided entirely by them. And I also have seen that hand demo months ago. However, I must admit that I am surprised at the precision with which these muscles are controlled in the demos. You cannot do that with a set of standard valves. We are using one intake and three outlet valves for different clutch release speeds and that's barely tuneable enough to get the job done for us (it's an on/off kind of thing with not quite reproducable timing).
