The kinder, gentler side of AI... making humans stronger instead of vice versa
Rob Hanna stashed this in Tools for Positive Change
This is a fascinating NYT series on Robotics that also parallels human applications with advancements in AI tech.
In case of a paywall, I'm posting a large section of the article below.
This is the third episode in a Bits video series, called Robotica, examining how robots are poised to change the way we do business and conduct our daily lives.
Engineers at the Johns Hopkins University Applied Physics Lab have developed a next-generation prosthetic: a robotic arm that has 26 joints, can curl up to 45 pounds and is controlled with a person’s mind just like a regular arm.
Researchers think the arm could help people like Les Baugh, who lost both arms at the shoulder after an electrical accident as a teenager. Now 59, Mr. Baugh recently underwent surgery at Johns Hopkins to remap the remaining nerves from his missing arms, allowing brain signals to be sent to the prosthetic.
Mr. Baugh’s custom socket can pick up brain signals to control the arms, known as Modular Prosthetic Limbs, or M.P.L., just by thinking about the movements.
Mike McLoughlin, the chief engineer of research and exploratory development at the lab, said that as the remapped nerves grew deeper, it was possible that Mr. Baugh would feel some sensation in his prostheses. Each arm has over 100 sensors, and other amputees who have had the same surgery reported being able to feel texture through the M.P.L.
Patients of varying disabilities have tested the arm in the lab and helped push the design forward.
The limb is modular, which means it can be broken off or built up to accommodate people with different needs — from a hand amputee to someone missing an entire arm. Quadriplegics or stroke survivors, who have lost the ability to move all or part of their bodies, can also use it as a surrogate arm.
But while the limb is fully functional, it still faces hurdles before making its way outside the lab. It will need approval from the Food and Drug Administration, which could mean a clinical trial.
Mr. McLoughlin also said the cost of the arm needed to be about a tenth of its current price to be viable in the marketplace. There are now about 10 fully functioning M.P.L.s, and each one costs an estimated $500,000.
“We’ve designed a Maserati here, but what most people will want is a good Toyota,” Mr. McLoughlin said. “The M.P.L. was intentionally designed to be as sophisticated as we could make it so that you could really push the state of the art, but ultimately for commercializing it, it needs to be a lower cost design.”
Since 2006, the lab has been awarded $120 million from a program run by the Pentagon’s Defense Advanced Research Projects Agency to help wounded warriors. The lab worked with technology developer and manufacturer HDT Global to make a prosthetic that mimics the human arm in dexterity and strength.
“The long-term goal for all of this work is to have noninvasive — no extra surgeries, no extra implants — ways to control a dexterous robotic device,” said Robert Armiger, project manager for amputee research at the Johns Hopkins lab. In the future, researchers envision a kind of cap with sensors that an amputee or paralyzed person could wear that would feed information about brain activity to the robotic arm.
The lab is starting to collaborate with industry partners to explore commercial opportunities. They hope the Modular Prosthetic Limb, or a version of it, will be available to consumers within a few years.
It's easy to forget all the good uses of robots since I'm regularly bombarded by what can go wrong. Thanks for reminding me that robots can help humans.
By the way it's possible the AI will become so intelligent that it will ignore us.
As I posted at the link you provided... ignoring us might not be such a great option either...
Yeah, I hope we learn to work together, as your NYTimes article atop this page suggests.
