Take a second to imagine all the people in your life. Your family, friends, coworkers. Your buddies down at the hackerspace, and anyone you chat with on IO and over the airwaves. Statistically speaking, one in four of these people has a disability of some kind, and needs help doing everyday things that you might not think twice about — simple things like opening doors or interacting with computers. Or maybe that one in four is you.
For the past 75 years, United Cerebral Palsy of LA (UCPLA) have been helping people with various developmental and intellectual disabilities to live independently with dignity. They work directly with members of the disabled community to develop assistive technology that is both affordable and dependable. UCPLA helps the disabled community with everything from employment to providing a creative outlet, and gives them the tools to do these things and more. Their mission is to help people be as independent as possible so they can feel good about themselves and enjoy a life without limits.
The people behind this non-profit are all about inclusion, access, and opportunity, and this is why we are proud to partner with UCPLA for the 2020 Hackaday Prize. With the world in upheaval, there is no better time to build a better future for everyone. You never know when you might need assistive technology. In addition to the open challenge that calls for everyone to work on a design, this year there is also a Dream Team challenge which offers a $3,000 per month stipend over the next two months to work on a team addressing one specific challenge. Apply for that asap!
What kind of challenges has UCPLA outlined for the Hackaday Prize? Let’s dive in and find out, and we’ll also hear from the UCPLA team in a Q&A video at the end of the article.

If your eyes are 20/20, you probably do not spend much time thinking about prescription eyeglasses. It is easy to overlook that sort of thing, and we will not blame you. When we found this creation, it was over two years old, but we had not seen anything quite like it. The essence of the Bear Paw Assistive Eating Aid is a swiveling magnet atop a suction cup base. Simple right? You may already be thinking about how you could build or model that up in a weekend, and it would not be a big deal. The question is, could you make something like this if you had not seen it first?
Over-engineered inventions with lots of flexibility and room for expansion have their allure. When you first learn Arduino, every problem looks like a solution for that inexpensive demo board and one day you find yourself wearing an ATMEGA wristwatch. Honestly, we love those just as much but for an entirely different reason. When all the bells and whistles are gone, when there is nothing left but a robust creation that, “just works,” you have created something beautiful. Judging by the YouTube comments of the video, which can be seen below the break, those folks have no trouble overlooking the charm of this device since the word “beard” appears 95 times and one misspelling for a “bread” count of one. Hackaday readers are a higher caliber and should be able to appreciate its elegance.
The current high-tech solution for self-feeding is a robot arm, not unlike this one which is where our minds went when we heard about an invention about eating without using hands, and we will always be happy to talk about robot arms.

An outstanding number of things most people take for granted present enormous hurdles for people with physical disabilities, including interaction with computers and other digital resources. Assistive technologies such as adaptive switches allow users who cannot use conventional buttons or other input devices to interact with digital devices, and while there are commercial offerings there is still plenty of room for projects like [Cassio Batista]’s DIY Low-cost Assistive Technology Switches.
[Cassio]’s project focuses on non-contact switches, such as proximity and puff-based activations. These are economical, DIY options aimed at improving accessibility for people who are unable to physically push even specialized switches. There are existing products in this space, but cost can be a barrier and DIY options that use familiar interfaces greatly improves accessibility.
Assistive technologies that give people the tools they need to have more control over their own lives in a positive, healthy way is one of the more vibrant and positive areas of open hardware development, and it’s not always clear where the challenges lie when creating solutions. An example of this is the winner of the 2015 Hackaday Prize, the Eyedrivomatic, which allows one to interface the steering of an electric wheelchair to a gaze tracking system while permanently altering neither device; a necessity because users often do not own their hardware.
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 help improve the condition of differently-abled people.
The participants were split into eight teams and they came up with some amazing results at the end of the five-day program.
Hands-On: Prosthetic Designs That Go Beyond
Three teams worked on projects based on Bionico – a myoelectric prosthesis
DIY Prosthetic Socket – a Human Machine Interface : [Mahendra Pitav aka Mahen] lost his left arm during the series of train bomb blasts in Mumbai in 2006, which killed 200 and injured over 700 commuters. He uses a prosthetic arm which is essentially a three-pronged claw that is cable activated using his other good arm. While it is useful, the limited functionality restricted him from doing many simple things. The DIY Prosthetic socket team worked with [Mahen] and [Nico Huchet] from MyHumanKit (who lost his right arm in an accident 16 years back), and fabricated a prosthetic forearm for [Mahen] with a modular, 3D printed accessory socket. Embedded within the arm is a rechargeable power source that provides 5V USB output at the socket end to power the devices that are plugged in. It also provides a second port to help recharge mobile phones. Also embedded in the arm was an IR reflective sensor that can be used to sense muscle movements and help trigger specific functions of add-on circuits, for example servos.

Starting this weekend, a group of 65 invited Maker’s from various disciplines, along with 20 awesome Mentors, will gather at the Maker’s Asylum in Mumbai for the five day S.T.E.A.M. Fabrikarium program. The aim is to improve the capabilities of the differently-abled by building and expanding upon existing open source projects. At the same time, the teams will learn more about rapid prototyping techniques.
Among the participants will be at least 15 differently-abled people who will be a part of the whole process of learning as well as providing their inputs on the problems being tackled. Participants have an opportunity to understand how design thinking works and work on improving the existing designs.
Participants will team up and choose from five existing open source projects:
- Bionico – a myoelectric prosthesis
- Braille rap – using a 3D printer as a braille embosser.
- e-Trotti – a low-cost, removable electrical assistance for wheelchair use, made from electric scooter parts.
- Project Shiva – customized and beautiful upper limb prosthetics.
- Flying Wheelchair – a wheelchair specially adapted for use while paragliding.
The Asylum’s fully-fledged workshop facilities offer a wood shop, a laser cutter, a CNC, several 3D printers, electronics tools and instruments and an infectious environment that will allow the participants to learn a lot during the five short days. While working on prototyping their projects, all teams will have constant access to a team of mentors and industry experts who will help solve their problems and give guidance when necessary.
The Maker’s Asylum includes fully-fledged workshop facilities for the build process, and the team succeeded in bringing onboard a slew of industrial partners and supporters to ensure that the program can be offered to the participants for free. That is a great way to bring makerspaces, makers, and the industry together in a symbiotic program that benefits society. The program was developed in collaboration with My Human Kit, a company from France who selected the five open-source projects mentioned above. The Fabrikarium is made possible via Bonjour-India, which fosters Indo-French partnerships and exchanges.
Hackaday is proud to be a part of this program and will be present to help document all of the awesome projects. Participants will share their progress on Hackaday.io, so watch for updates over the coming week. To get an idea of what to expect at the S.T.E.A.M. Fabrikarium 2018, check out the video from an earlier version embedded below.

If you take a walk across the centre of your city, you will find it to be a straightforward experience with few inconveniences. The occasional hold-up at a pedestrian crossing perhaps, or maybe a crowd of people in a busy shopping area. If however you take the same walk in the company of a wheelchair user you are likely to encounter an entirely different experience. The streets become a nightmare of obstacles to avoid and inaccessible areas requiring a detour, and suddenly what had been a pleasurable experience becomes a significant effort. Despite building and planning code updates to improve the situation, and millions of dollars invested in ramps, lifts, and other improvements, there remain so many problems to be addressed. Meanwhile legislators and the general public imagine that something has been done, the accessibility box has been ticked, and they can move on to the next thing that captures their attention.
The paralympian athlete [Tatyana McFadden] is an ambassador for the Toyota Mobility Foundation’s Mobility Unlimited Challenge, a global competition with the aim of improving mobility for people with disabilities. She’s written a piece introducing the challenge from her informed point of view as a wheelchair user, and makes the point that the basic design of a chair has not significantly changed since the 1930s. Her sentence: “There may be more hype around Bitcoin, but innovators could have far more impact if they turned their attention to how they can make the freedom to move available to all.” is one to make those of us with an interest in technology stop and think. To introduce the challenge they’ve released a glossy video, and we’ve placed it below the break.
As part of this year’s Hackaday Prize, we had an Assistive Technologies section that attracted some fantastic entries. That demonstrates that our community has plenty of people with the required skills, experience, and ideas to make a difference, and we hope that some of them might be among the entries for the Mobility Unlimited competition. If it excites your interest, we’d like to urge you to give it a second look.
A word of warning though – take care to avoid the Engineer Saviour Trap.

The Assistive Technology challenge of the Hackaday Prize received a large number of projects addressing many socially relevant problems. Mobility and transportation needs are a big challenge for those with limb disabilities. Not every country has proper, state-subsidised health care systems, and for many people in third world countries, devices such as wheel chairs are just not affordable. [Alessio Fabrizio] and his team developed TooWheels — an Open Source DIY wheelchair which can be customized and built using low-cost, local materials around the world and is one of the winners of the Assistive Technologies challenge round.
Originally conceived as a sport wheelchair, it has now evolved to answer different needs, due to feedback from the users and the community involved in the project. [Alessio] designed the project to be built from materials and resources easily available to any DIY maker at today’s Fab Labs and Makerspaces. The team have provided a detailed BOM to help procure all the required materials, instruction manual and drawings for assembly, and all the CAD files with customization instructions. Already, teams in Ecuador, India and Italy have replicated and built their own version of the TooWheel wheelchair. This confirms that the project is well documented and allows anyone around the world to download the plans and follow instructions to build their own wheelchair.
The wheelchair is built from CNC cut plywood sheets, aluminum pipes and bicycle parts and wheels. This makes it substantially cheaper compared to commercial wheelchairs, making it especially relevant for people in third world areas or where health care is not subsidised. The ease of customization allows fabrication of different wheelchair designs for sports, off-road or city use. The team is looking to bring this low-cost design to people around the world and are keen to collaborate with teams around the world to make it happen.
