Bird Beats Cancer With The Help Of A 3D-Printed Prosthetic

Posted on by

It’s a reasonable certainty that 3D-printing is one day going to be a huge part of medicine. From hip implants to stents that prop open blood vessels to whole organs laid down layer by layer, humans will probably benefit immensely from medical printing. But if they do, the animals will get there first; somebody has to try this stuff out, after all.

An early if an unwilling adopter of 3D-printed medical appliances is [Jary], a 22-year-old Great Pied Hornbill, who recently received a 3D-printed replacement for his casque, the large, mostly hollow protuberance on the front the bird’s skull leading …read more

DIY Socket for Prosthetics Contains Power Supply, Charger

Posted on by

Innovation in prosthetics is open to anyone looking to enhance the quality of life, but there’s an aspect of it that is sometimes under-served. The DIY Prosthetic Socket entry to the Hackaday Prize is all about the foundation of a useful prosthesis: a custom, form-fitting, and effective socket with a useful interface for attaching other hardware. While [atharvshringaregt] is also involved with a project for a high-tech robotic hand with meaningful feedback, socket fitting and design is important enough to be its own project.

The goal is not just to explore creating these essential parts in a way that’s accessible …read more

Rapidly Prototyping Prosthetics, Braille, and Wheelchairs

Posted on by

We live in an amazing time where the availability of rapid prototyping tools and expertise to use them has expanded faster than at any other time in human history. We now have an amazing ability to quickly bring together creative solutions — perfect examples of this are the designs for specialized arm prosthetics, Braille printing, and custom wheelchair builds that came together last week.

Earlier this month we published details about the S.T.E.A.M. Fabrikarium program taking place at Maker’s Asylum in Mumbai. The five-day event was designed to match up groups of makers with mentors to build assistive devices which …read more

AI Prosthesis Is Music To Our Ears

Posted on by

Prostheses are a great help to those who have lost limbs, or who never had them in the first place. Over the past few decades there has been a great deal of research done to make these essential devices more useful, creating prostheses that are capable of movement and more accurately recreating the functions of human body parts. At Georgia Tech, they’re working on just that, with the help of AI.

[Jason Barnes] lost his arm in a work accident, which prevented him from playing the piano the way he used to. The researchers at Georgia Tech worked with him, …read more

Need A Hand? How About Two?

Posted on by

A helping hand goes a long way to accomplishing a task. Sometimes that comes in the form of a friend, and sometimes it’s a pair of robotic hands attached to your arm.

Italian startup [Youbionic] have developed this pair of 3D printed hands which aim to extend the user’s multi-tasking capacity. Strapped to the forearm and extending past the user’s natural hand, they are individually operated by flexing either the index or ring fingers. This motion is picked up by a pair of flex sensor strips — a sharp movement will close the fist, while a slower shift will close …read more

Servo-Controlled Eyeball Makes a Muggle Moody

Posted on by

Even when you bear a passing resemblance to the paranoid Auror of the Harry Potter universe, you still really need that wonky and wandering prosthetic eye to really sell that Mad-Eye Moody cosplay, and this one is pretty impressive.

Of course, there’s more to the [daronjay]’s prosthetic peeper than an eBay doll’s eye. There’s the micro-servo that swivels the orb, as well as a Trinket to send the PWM signal and a pocket full of batteries. The fit and finish really tie it together, though, especially considering that it’s made from, well, garbage — a metal food jar lid, a …read more

You’d Print A Part, But Would You Print A Foot?

Posted on by

Born with just one foot, [Nerraw99] had to work around prosthetics all his life. Finally getting fed up with the various shortcomings of his leather and foam foot, he designed, tweaked, printed and tested his own replacement!

After using Structure Sensor to scan both his feet, [Nerraw99] began tooling around with the model in Blender and 3D printing them at his local fablab/makerspace: MakerLabs. It ended up taking nearly a dozen printed iterations — multiple printing issues notwithstanding — to get the size right and the fit comfortable. Not all of the attempts were useless; one version turned out to …read more

The Hackaday Prize: Exoskeletons for the Masses

Posted on by

While medical facilities continue to improve worldwide, access to expensive treatments still eludes a vast amount of people. Especially when it comes to prosthetics, a lot of people won’t be able to afford something so personalized even though the need for assistive devices is extremely high. With that in mind, [Guillermo Herrera-Arcos] started working on ALICE, a robotic exoskeleton that is low-cost, easy to build, and as an added bonus, 100% Open Source.

ALICE’s creators envision that the exoskeleton will have applications in rehabilitation, human augmentation, and even gaming. Also, since it’s Open Source, it could also be used as …read more

Fail of the Week: Good Prosthetic Hand Design Goes Bad

Posted on by

Is this a case of a good design gone wrong in the build phase? Or is this DIY prosthetic arm a poor design from the get-go? Either way, [Will Donaldson] needs some feedback, and Hackaday is just the right place for that.

Up front, we’ll say kudos to [Will] for having the guts to post a build that’s less than successful. And we’ll stipulate that when it comes to fully articulated prosthetic hands, it’s easy to fail. His design is ambitious, with an opposable thumb, fingers with three phalanges each, a ball and socket wrist, and internal servos driving everything. …read more

An ExoArm For The Elderly

Posted on by

Prosthetic and assistive technologies have come have come a long way in recent years. When there are not only major medical research organizations, but individuals getting on board designing tools to improve the lives of others? That’s something special. Enter a homebrew essay into this field: ExoArm.

Attached to the body via what was available — in this case, the support harness for a gas-powered weed-eater — which distributes the load across the upper body and an Arduino for a brain, ExoArm designer [Kristjan Berce] has since faced roadblocks with muscle sensors meant to enable more instinctive control. …read more
