Robotics 56

An anonymous reader writes "The MK-1 Robotic Arm from HDT Global comes from a DARPA sponsored project to create a highly advanced prosthetic limb. The disco dance moves shown at the beginning of this video show off the impressive dexterity of the modular servo units that comprise the MK-1 Robotic Arm." Internet rudeness alert: the (impressive) video starts autoplaying, with sound; you have been warned.

Invert the joint and put a foot at the end. I want to see it kick ass.

Warwick Allison (209388) | more than 2 years ago | (#37184800)

Actually, it's slow. 120 degrees per second according to the video (3 seconds for a complete revolution). That's not fast enough to wave, let alone kick.

What about sinistrality? (2)

Does this arm also achieve sinistrality, or is it restricted to dexterity? :-)

NeuroElectrical Interface (2)

sycodon (149926) | more than 2 years ago | (#37176996)

One wonders where the state of the art is as far as neuro-electrical interconnections.

Re:NeuroElectrical Interface (1)

delinear (991444) | more than 2 years ago | (#37177388)

I was wondering the same. The brief blurb on the page talks about the possible use in prosthetics, but unless you have a control mechanism capable of making use of the full range of something like this, you essentially just have a very expensive plastic arm. It's great that the technology is there when it's needed, I just don't think that will be for a while yet.

Re:NeuroElectrical Interface (2)

hitmark (640295) | more than 2 years ago | (#37178940)

The latest that is available in the field is moving the nerves around so that what was once moving the arms and fingers now manipulate small muscles on the chest.

This is then mapped into the electronics.

That's actually pretty cool. I'd like to pair it with an ABB, Kuka, or Fanuc controller and use it for something industrial, but then again, I'm an industrial nerd.

Re:Pretty cool (1)

Actually, to create a truly great dancing robot, you need to get one of the new-fangled model of the ABB, the ABBA.

Re:Pretty cool (1)

nameer (706715) | more than 2 years ago | (#37177688)

The video says that the servo control is handled on board the module. So, you would need a trajectory planner and interpolator, but not amplifiers or drives. There is no comment on how to set up the tuning (for good control, robots require non-linear control laws). I *think* the newest ABB robot controllers, with some undocumented options, can directly feed interpolation points out over CAN bus (accepted by these modules), so it might be possible.

Re:Pretty cool (1)

pnewhook (788591) | more than 2 years ago | (#37178134)

No, because stability is too difficult to prove. You can achieve good control with classical control techniques.

On jobs and society (1)

Sir_Eptishous (873977) | more than 2 years ago | (#37178230)

Once tech like this becomes commoditized(20 years?), just like the pc and the cell phone did, it's going to put loads of people out of work. Devices like this will be used to do everything from home health aid, janitorial, picking fruit, and mining. Interesting how that timeline will coincide with a general downward trend in education in the U.S. We already see on the horizon that many "white collar" jobs(financial, creative, etc;) will be lost to software. I find it fascinating how much of a double-standard there is in the media regarding this subject. A constant clamoring about jobs, the unemployment rate, who brings jobs to whose district, etc;, yet not a whisper about things like this. Obviously tech like this will only proliferate, and eventually become "the norm", not only for use as prosthetics, but for a vast array of uses.

Re:On jobs and society (1)

DeadDecoy (877617) | more than 2 years ago | (#37178750)

It depends. If robots take up some of the menial labor, humans are afforded more time to work on other problems. The calculator might have replaced pure number crunchers, but that doesn't mean people don't practice math anymore. There are still physicist, mathematicians, and engineers. Odds are, if I robot assistant is developed, we'll have robot repair shops, programming centers, and robot insurance; while having fewer fruit pickers and maids. Humans will probably be replaced for certain tasks, but since we define society as a group of humans, we will probably never be rid of one another.

I tend to agree with you about who will be displaced first, but I don't think we have to anticipate more widespread adoption of robots for a long, long time. We will probably have to cross the uncanny valley [wikipedia.org] in one quantum leap before society in general will accept robots in the roles of humans. As you suggest, roles that keep robots out of sight/out of mind will be about the only places robots can be effectively deployed until they are indistinguishable from us. Labor intensive tasks like agriculture and domestic maintenance, which you mentioned, would be where I would target my robotic R&D dollars right now. Human-level replacement prostheses are truly nice, but my personal uncanny valley is pretty steep, and pretty wide. I wouldn't want to shake hands with a prosthesis, if I knew before hand (not trying to be punny) it was artificial.

Re:Can't cross the uncanny valley in a few steps.. (1)

CayceeDee (1883844) | more than 2 years ago | (#37189292)

A really amazing example of irrationality overwhelming rationality. You would refuse to shake hands with a person who has a prosthetic hand when you know they have a prosthetic hand simply because they have a prosthetic hand.

Re:On jobs and society (0)

Anonymous Coward | more than 2 years ago | (#37178968)

I too have been thinking about this.

I have been watching a lot of 'how its made'. I see huge factories where there are maybe a few dozen people moving a few things around. Making thousands of items an hour. It really is just a matter of time before it is all automated.

Menial jobs *will* be automated. There will be no 'get a job at mcdonalds' As they will have automated everything to make a perfect burger everytime and served in less than 2 mins.

Even people heavy companies such as foxcon are automating.

We are quickly going to end up with a society where a small group of people watch over a large array of automated machines. The rest of us?...

Get a good AI in the mix and even 'supervising/creating' is automated.

If these things happen... People think unemployment is bad now. Just wait...

Paul Fernhout (109597) | more than 2 years ago | (#37182294)

You're right. Here is a 12 minute YouTube video I made that talks about a balance between five interwoven economies that shifts with cultural change and technological change:
      http://www.youtube.com/watch?v=4vK-M_e0JoY [youtube.com]
"This video presents a simplified education model about socioeconomics and technological change. It discusses five interwoven economies (subsistence, gift, exchange, planned, and theft) and how the balance will shift with cultural changes and technological changes. It suggests that things like a basic income, better planning, improved subsistence, and an expanded gift economy can compensate in part for an exchange economy that is having problems. "

A PDF file of the presentation is here:
      http://www.pdfernhout.net/media/FiveInterwovenEconomies.pdf [pdfernhout.net]

Other related stuff by me:
    http://knol.google.com/k/beyond-a-jobless-recovery [google.com]

But right now, pretty much not one gets this. Mainstream economists are in denial. They just assume infinite demand (not limits from environmentalism, voluntary simplicity, or a law of diminishing or negative returns), that robots and AI and better design and voluntary social networks can't replace most paid human labor, that wealth be evenly distributed (not centralized to the owners of capital), that the mean on the bell curve on IQ will suddenly jump globally from 100 (remember, half below) to 200 to everyone can have great high technology creative jobs, and so on.

Some alternative economists have called for change, but are so far mostly ignored:
    http://www.responsiblefinance.ch/ [responsiblefinance.ch]

Anyway, I've put all my resources into understanding these issues and telling peopel about solutions to the point of my own family's economic collapse. But for the most part no one cares; well, I should really say, many people care do about the problem, or say they care, (especially when it effects them personally or someone they care about), but most people just want a solution that does not entail any substantial change to the status quo. It seems our current political and economic leadership would rather drive our society off a cliff to collapse rather than consider things like a basic income, expanded gift economy, better democratic resource based planning, promoting local subsistence via 3D printing and organic gardnening robots, and so on.

Anyway, there are solutions if we can find the collective social will to put them in place. Already the US averages about US$700 per month per citizen in payments for social security, schooling, unemployment, and disability. We could bring that up to US$1000 or even $2000 a month. And we could get rid of or shorten patents and copyrights and do other things to promote a gift economy. And so on. Someday we will probably do all those things or similar ones if we are to survive and thrive. It's just a question of how much suffering will happen before then.

But, as Martin Ford said, while military planners are planning for and funding the development of robots that can do tasks in unstructured battlefields, economists continue to assume robots and AI will never take over most work in a highly structured factory or office.

Post-human arms (1)

ortholattice (175065) | more than 2 years ago | (#37178426)

This is impressive and seems to have essentially reached a goal of emulating a human arm.

What really impressed me, though, was the modularity of the arm. Presumably this would allow configurations other than human-imitating arms. One could imagine post-human configurations - whether for prosthetic purposes, extending the capabilities of a normal human, or as a stand-alone robot for specialized tasks. E.g. (off the top of my head) would 7 fingers be more useful than 5, or perhaps an arm with two (or several) elbow joints, or auxilliary fingers along the arm, or a robot with 3 or 4 arms? Or is the human arm - "perfected" by evolution - the most effective configuration possible?

Looks like it could self assemble.. meaning several modules could be fit thru a fairly narrow diameter pipe in a snakelike configuration.

If I was a human chinese worker, I would be scared of these taking over my shitty job. Us fat americans could make a factory with these and not have to pay union wages and benefits. Three shifts, limited task lighting only, and automated forklifts tied with the savings in trans oceanic shipping should bring cost in line. I would love to see an MBA do a study on that. Toss in a couple of human managers for QA purpose, maybe not.

Its pretty nice (1)

Anonymous Coward | more than 2 years ago | (#37179906)

Im part of the software team that is developing the MK2, (previously MK1), we showed the robot at AUVSI last week. I developed the low level driver communications, part of the control software for each joint, the network gateway and UI interfaces for the system using C#. I can give some vague details:

Some details about the dancing:
- 27 degrees of freedom, 120 deg/s per joint.
- Capable of generating a lot of torque within a small package (I dont think we have competitors that can currently match us)
- About 25 points with minimum jerk interpolation, had to move each joint by joint to get to the desired position:(
- We didn't have time to develop end point control or object avoidance for the demo at AUVSI, almost got socked in the face when developing the dance.
- The video is speed up by 4x, its actually much slower in the dance routine. The arms can go pretty fast, but the combined current draw of the whole system at the highest speeds will easily trip our power supply.
- This will be used primarily for bomb disposal.
- The hands were retrofitted from our MK1 system at the last moment, the system is modular enough to support interchanging all of its joints in any configuration.

The Prosthetic Limb:
- Mostly APL Higher Level Control Algorithms,
- About the weight of a human arm.
- The amount of complexity in the thumb alone is equivalent to the whole upper arm
- The system is designed to run off a battery pack in the arm itself, so no car battery strapped to the poor guy using this. At full speed, it will kill the battery within minutes, normal operation should yield several hours.
- the whole system feels realistic when its being controlled with the cyber glove at APL. One of the engineers was able to feed himself m&ms using a spoon.
- Its currently being tested on a monkey to develop better control algorithms

Force Feedback Servos (0)

Anonymous Coward | more than 2 years ago | (#37180536)

What was really interesting was the servos that have force feedback built in. This means that it can bump into something and detect that before continuing along the way possibly hurting someone nearby. Standard servos do not have this feedback mechanism which is why most medium to large robots these days are dangerous to be around. Willow Garage's PR2 has arms that use a different approach but are designed to allow interaction with humans and other delicate materials.
