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.
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 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.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
Engineers need workhorse materials with beefy mechanical properties for industrial designs made with 3D printing. Very few have been designed from the ground up for additive manufacturing, but that picture is beginning to change.
