Thanks for another informative article Ann!  The links are great.  I'd really like to see more in the slide show. 

Robots with Common Sense made in the USA.  Now, that's something new.

Glad you enjoyed my report, Nadine. Actually there's been a lot of intelligent robot design here in the US, but much of it's been aimed at military or rescue robots. Some's also been done in industrial robots, but not with the specific goal of a robot like Baxter. I'm really interested to see what developers do with the SDK.

Bone rasp or industrial tool?

My husband just told me he showed this article to one of the guys at work, who said the bone rasp looks like a diamond studded borer used in industrial mining. I've been avoiding thinking about what this femur borer actually does, but--Ouch!

Didn't realize that 3D printing for medical applications are over 30 percent and trending upward.  It makes sense because 3D printing is a great fit for creating individualized, custom parts out of titanitum at a reasonable cost and with a rapid turn-around time.

I actually thought the bone rasp looked like a medieval weapon, Ann.

I can see a lot of applications where the Baxter robot can be used in assembly line application. The robot can handle the arduous task of picking and placing a part for the operator to complete some fine assembly work like fitting tight tolerance components together. The operator can then safely hand the part to another robot for assemnbly or packout.

Enjoyed your firsthand account of Baxter, Ann. Sounds like "he" behaves as the company said he would, but I guess the proof of his usefulness on the factory floor will be in the pudding. Generally he sounds quite impressive, though!

Yes, the photo of the femur bone rasp is seriously daunting! Looks more like a weapon for a scifi superhero than a doctor...hopefully patients are under heavy anesthesia before something like this is used on them. The innovations in fabrication of the tool are quite impressive, though.

Hi Ann--Baxter has gotten a lot of attention since it was rolled out.  I wonder about the ultimate safety in a real environment.  To do its job it has to learn some places or zones where it expects "parts" and everywhere else would be an exception so the sensors can stop it.  If your body is where a part should be, how does it know the difference?

I can imagine a learning process where the entire profile of motion, including all 3D forces and accelerations are recorded and stored, and some threshold set to that if during the entire operation a threshold is exceeded it stops.  I don't know if that is more or less what they are doing.  Even if that is true, a human has to set the thresholds in the learned profile, and production engineers being human, will tend to set the thresholds to eliminate any false alarms.  That opens the door to injury.

Do you have any deeper insight into how Baxter will always know the difference between work and a human?

Greg, I knew medical and dental was a major app area but not that it had reached such a high percentage. I agree, it makes total sense. The reduction in cost per item of a titanium device is what amazed me the most.

After a year or so of missteps, false starts, retractions, and postponements, inkjet office printer giant Hewlett-Packard has finally revealed just what it plans to do in 3D printing.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team 100 to make (about $161 US).
