Amos Winter: The cheap all-terrain wheelchair

Amos Winter: The cheap all-terrain wheelchair


Translator: Joseph Geni
Reviewer: Morton Bast Living with a physical
disability isn’t easy anywhere in the world, but if you live in a country
like the United States, there’s certain appurtenances available
to you that do make life easier. So if you’re in a building,
you can take an elevator. If you’re crossing the street,
you have sidewalk cutouts. And if you have to travel
some distance farther than you can do under your own power,
there’s accessible vehicles, and if you can’t afford one of those, there’s accessible public transportation. But in the developing world,
things are quite different. There’s 40 million people who need
a wheelchair but don’t have one, and the majority of these
people live in rural areas, where the only connections to community,
to employment, to education, are by traveling long
distances on rough terrain often under their own power. And the devices usually
available to these people are not made for that context,
break down quickly, and are hard to repair. I started looking at wheelchairs
in developing countries in 2005, when I spent the summer assessing
the state of technology in Tanzania, and I talked to wheelchair users, wheelchair
manufacturers, disability groups, and what stood out to me is that there wasn’t a device available that was designed for rural
areas, that could go fast and efficiently on many types of terrain. So being a mechanical engineer, being at MIT and having lots
of resources available to me, I thought I’d try to do
something about it. Now when you’re talking
about trying to travel long distances on rough terrain, I immediately thought of a mountain bike, and a mountain bike’s good at doing this because it has a gear train, and you can shift to a low gear
if you have to climb a hill or go through mud or sand and you get a lot of torque
but a low speed. And if you want to go
faster, say on pavement, you can shift to a high gear, and you get less torque,
but higher speeds. So the logical evolution here is to just make a wheelchair
with mountain bike components, which many people have done. But these are two products
available in the U.S. that would be difficult to transfer
into developing countries because they’re much, much too expensive. And the context I’m talking about is where you need to have a product
that is less than 200 dollars. And this ideal product
would also be able to go about five kilometers a day so you
could get to your job, get to school, and do it on many,
many different types of terrain. But when you get home or want
to go indoors at your work, it’s got to be small enough and maneuverable
enough to use inside. And furthermore, if you want it to last
a long time out in rural areas, it has to be repairable using the local
tools, materials and knowledge in those contexts. So the real crux of the problem here is, how do you make a system
that’s a simple device but gives you a large
mechanical advantage? How do you make a mountain
bike for your arms that doesn’t have the mountain
bike cost and complexity? So as is the case with simple solutions, oftentimes the answer is right in front
of your face, and for us it was levers. We use levers all the time,
in tools, doorknobs, bicycle parts. And that moment of inspiration,
that key invention moment, was when I was sitting
in front of my design notebook and I started thinking
about somebody grabbing a lever, and if they grab
near the end of the lever, they can get an effectively long lever and produce a lot of torque
as they push back and forth, and effectively get a low gear. And as they slide
their hand down the lever, they can push with a smaller
effective lever length, but push through a bigger
angle every stroke, which makes a faster rotational speed,
and gives you an effective high gear. So what’s exciting about this system is that it’s really, really
mechanically simple, and you could make it using technology that’s been around for hundreds of years. So seeing this in practice, this is the Leveraged Freedom Chair that, after a few years of development, we’re now going into production with, and this is a full-time wheelchair user — he’s paralyzed — in Guatemala, and you see he’s able to traverse
pretty rough terrain. Again, the key innovation of this technology
is that when he wants to go fast, he just grabs the levers near the pivots
and goes through a big angle every stroke, and as the going gets tougher, he just
slides his hands up the levers, creates more torque, and kind
of bench-presses his way out of trouble through the rough terrain. Now the big, important point here is that the person is the complex
machine in this system. It’s the person that’s sliding
his hands up and down the levers, so the mechanism itself can be very simple and composed of bicycle parts you
can get anywhere in the world. Because those bicycle parts are so ubiquitously available,
they’re super-cheap. They’re made by the gazillions
in China and India, and we can source them
anywhere in the world, build the chair anywhere,
and most importantly repair it, even out in a village
with a local bicycle mechanic who has local tools, knowledge
and parts available. Now, when you want to use the LFC indoors, all you have to do is pull
the levers out of the drivetrain, stow them in the frame, and it
converts into a normal wheelchair that you can use just
like any other normal wheelchair, and we sized it like a normal wheelchair, so it’s narrow enough to fit
through a standard doorway, it’s low enough to fit under a table, and it’s small and maneuverable
enough to fit in a bathroom and this is important so the user
can get up close to a toilet, and be able to transfer off just like he could in a normal wheelchair. Now, there’s three important
points that I want to stress that I think really hit
home in this project. The first is that this
product works well because we were effectively able to combine rigorous engineering science
and analysis with user-centered design focused on the social and usage
and economic factors important to wheelchair users
in the developing countries. So I’m an academic at MIT,
and I’m a mechanical engineer, so I can do things like look at the type
of terrain you want to travel on, and figure out how much
resistance it should impose, look at the parts we have
available and mix and match them to figure out what sort
of gear trains we can use, and then look at the power and force
you can get out of your upper body to analyze how fast you should
be able to go in this chair as you put your arms
up and down the levers. So as a wet-behind-the-ears
student, excited, our team made a prototype, brought that prototype to Tanzania,
Kenya and Vietnam in 2008, and found it was terrible because we didn’t get
enough input from users. So because we tested it
with wheelchair users, with wheelchair manufacturers,
we got that feedback from them, not just articulating their problems,
but articulating their solutions, and worked together to go back
to the drawing board and make a new design, which we brought back
to East Africa in ’09 that worked a lot better than a normal
wheelchair on rough terrain, but it still didn’t work well
indoors because it was too big, it was heavy, it was hard to move around, so again with that user feedback,
we went back to the drawing board, came up with a better
design, 20 pounds lighter, as narrow as a regular wheelchair, tested
that in a field trial in Guatemala, and that advanced the product to the point where we have now that it’s going
into production. Now also being engineering scientists, we were able to quantify the performance
benefits of the Leveraged Freedom Chair, so here are some shots
of our trial in Guatemala where we tested the LFC
on village terrain, and tested people’s biomechanical outputs, their oxygen consumption,
how fast they go, how much power they’re putting out, both in their regular
wheelchairs and using the LFC, and we found that the LFC
is about 80 percent faster going on these terrains
than a normal wheelchair. It’s also about 40 percent more
efficient than a regular wheelchair, and because of the mechanical
advantage you get from the levers, you can produce 50 percent higher torque and really muscle your way
through the really, really rough terrain. Now the second lesson
that we learned in this is that the constraints on this design
really push the innovation, because we had to hit
such a low price point, because we had to make
a device that could travel on many, many types of terrain
but still be usable indoors, and be simple enough to repair, we ended up with a fundamentally
new product, a new product that is an innovation in a space that really hasn’t
changed in a hundred years. And these are all merits that are not
just good in the developing world. Why not in countries like the U.S. too? So we teamed up with Continuum, a local product design firm here in Boston to make the high-end version,
the developed world version, that we’ll probably sell primarily
in the U.S. and Europe, but to higher-income buyers. And the final point I want
to make is that I think this project worked
well because we engaged all the stakeholders that buy into this
project and are important to consider in bringing the technology
from inception of an idea through innovation, validation,
commercialization and dissemination, and that cycle has to start
and end with end users. These are the people that define
the requirements of the technology, and these are the people that have
to give the thumbs-up at the end, and say, “Yeah, it actually works.
It meets our needs.” So people like me in the academic space, we can do things like innovate
and analyze and test, create data and make
bench-level prototypes, but how do you get that bench-level
prototype to commercialization? So we need gap-fillers like Continuum
that can work on commercializing, and we started a whole NGO
to bring our chair to market — Global Research Innovation Technology — and then we also teamed up with a big
manufacturer in India, Pinnacle Industries, that’s tooled up now
to make 500 chairs a month and will make the first
batch of 200 next month, which will be delivered in India. And then finally, to get this
out to the people in scale, we teamed up with the largest
disability organization in the world, Jaipur Foot. Now what’s powerful about this model is when you bring together
all these stakeholders that represent each link in the chain from inception of an idea all the way to implementation
in the field, that’s where the magic happens. That’s where you can take
a guy like me, an academic, but analyze and test
and create a new technology and quantitatively determine
how much better the performance is. You can connect with stakeholders
like the manufacturers and talk with them face-to-face
and leverage their local knowledge of manufacturing
practices and their clients and combine that knowledge
with our engineering knowledge to create something greater
than either of us could have done alone. And then you can also engage the end user in the design process, and not
just ask him what he needs, but ask him how he thinks
it can be achieved. And this picture was taken
in India in our last field trial, where we had a 90-percent
adoption rate where people switched to using our Leveraged Freedom
Chair over their normal wheelchair, and this picture specifically is of Ashok, and Ashok had a spinal injury
when he fell out of a tree, and he had been working at a tailor,
but once he was injured he wasn’t able to transport
himself from his house over a kilometer to his shop
in his normal wheelchair. The road was too rough. But the day after he got
an LFC, he hopped in it, rode that kilometer, opened up his shop and soon after landed a contract
to make school uniforms and started making money, started
providing for his family again. Ashok: You also encouraged me to work. I rested for a day at home. The next day I went to my shop. Now everything is back to normal. Amos Winter: And thank you
very much for having me today. (Applause)

    At least he learned one hugely important thing. Go to the disabled themselves and ask them what works!!!! Do NOT make assumptions as a non-disabled person! As a disabled veteran in America I can tell you that many times ramps, lifts, etc. are poorly placed, only provide partial access OR (in violation of the ADA) they don't exist at all!

    Amos Winter, you've identified a problem and developed a solution. Have you posted drawings on-line so people can fabricate their own? Have you found a manufacturer willing to provide kits at a reasonable price? How do you intend to implement your excellent solution? Only when the solution is widely available will your solution have meaning.

    Why not make the low priced 200 version for the rest of the world? Lots of disabled people in the west have no money for high end versions. Its not like disability incomes in the western world are high enough, especially if one also has other medical costs. Insurances are throwing more and more medicines out of the insurances.

    There are so many people here who could use a low priced chair like this. Why not set up a facebook page together, see if you can buy a set of 100 together with a group? It would take some good organising, and maybe a volunteer with a truck to bring the chairs to some central points across a state but if one advertises this in facebooks disability pages, it should not be impossible to find 100 people.

    only $2,995 for the low end version. missed the price point x10. why? still made from cheap bike parts. The excuse that they are made from modern bike parts that are available in the U.S. market is rediculous. A cheap walmart bike still uses the same bike tech that went into a bike built 30 years ago. Consequently, most bike shops carry the bearings and gears to repair them. Their other claim is that it costs them $1000 per unit from india. how about a modular wheel like the Pivot by Rio Mobility or NuDrive, or The Wijit. These systems all use standard wheelchairs and either replace the rear wheels or clamp onto the rear wheels. fitting these levered off road wheels with standard quick release mechanisms and making them modular with current quick release wheels would cut shipping costs and production costs, and make the system a lot more affordable for the average wheelchair user in countries that are far away from India.

While on the device it allowed you to reach high and low items in the grocery store. I was looking at electric wheelchairs when I found this wonderful device [name?] I cannot find the site again!

When I went to their site to inquiry about 1 I was floored at what the price they are asking for this chair $2745 lowest and $5695 for their highest. As far as I care they can keep their crap.

    This guy was my graduate student adviser for an undergraduate project. Great guy! Glad to see him on a TED talk. So many comments ask why not a cheaper wheelchair for US and Europe. The unfortunate truth is that, as a graduate student and researcher in the US, it is easier to get support and funding to develop technology for underprivileged communities outside the US rather than inside. Part of this is that people like Amos could get free bike donations to get parts, and recruit undergrads or partner with people in underprivileged communities to make and distribute the wheelchairs. And the people who get them are happy to get any help, and they are willing to fix things when they break. But try to do that in the US? No way. The complaints would come rolling in. "It doesn't look professionally made" or "It has some sharp edges" or "Its not comfortable enough" or "It broke and I don't want to fix it" or "You're using public funds to help deadbeats" or "Its too squeeky". Blah blah blah.

    This wheelchair could work but only for a select group of people. This technology would be almost worthless to any disabled person with upper body issues. What if you're missing one arm? how do you drive this thing. You can see from the videos that the user is exerting a large amount of upper body strength. Many disabled people lack upper body strength. Hypothetically, lets takes the designer standing up, then another person wind up and hit him strait in the spine, or kidneys, crack a few ribs or even just knock the wind out of him. Following that, I ask that you personally demonstrate how well your wheelchair design functions. After sustaining the said injuries, please demonstrate how much torque and how much speed this wheelchair has to offer. Let us know how you feel after using it too. Enough said?

    I agree that these $200.00 chairs should be accessible to Americans. Even plain hand-push wheelchairs with no bells and whistles are $600.00! I can't use my right hand, so I'm out of the loop for independence unless I have a power wheelchair. May I suggest to you who are interested in getting them made in the U.S. that you email Amos Winter? See if he has any ideas. I looked up his email address for you. It will be interesting to see if he answers! 😉 [email protected]

    I would love to help develop a true off road wheelchair. Not all chair users live in urban settings. Some of us live in rural areas and live a "normal" life. Yes I mow my on yard, I do my own mechanics, I weld, I do carpentry, I maintain my own home and until recently my own farm (cattle). However, being a para for 38 years and using a manual chair has taken it tole on my shoulders and have had to resort to using a electric chair. This has been extremely limiting. I have been building my own adaptive equipment for years due to the fact that either it wasn't invented, cost restraints or simply wasn't built heavy enough for what I needed. Mostly due to the fact it hasn't been invented. Any help I can offer from my experience I more than happy to do. If someone needs my help (other than funding, I am broke flatter than pee in the road), would tickle more than a feather loose in grandpa's cap. Don't let the southern speak let you think I am mentally challenged. I am just comfortable with it.

    If you want full mobility for trips of 10 miles or so and you have arm strength consider the Organic Transit ELF, front photo seen in my avatar. It has fully enclosed body but is considered a bicycle under federal ebike laws so no license or insurance! The comfortable sliding seat lets you fold up a compact wheelchair in the space where passengers would ride. It has full DOT lighting, signals, horn and is very safe in collisions. It has a solar panel roof for self charging or you can plug it in. OT works with the disabled to set you up or you can find a used one starting around $4K. It uses hand controls on a handlebar and operates like a bike. Your feet can be strapped in to the pedals. You can have true freedom from taxis or vans so it can save money in the long run. I'm only slightly disabled but I got rid of my car 4 years ago and have really enjoyed the pollution free ELF and I pedal for exercise but the motor will take you without pedaling. It has cargo room for more groceries than you ever buy at one time but no it won't climb stairs. OrganicTransit.com or see the many ELF videos here on Youtube.

    It does seem strange when you consider that mass produced Wheelchairs are selling at Walmart and Walgreens $150 (similar to the price of a China-made entry level bicycle) yet this $200 wheelchair lists for $4500 and up here in the USA. I get that the USA versions must fold up and fit in a car trunk but the difference seems excessive. Maybe give the patent away for free to any company that will produce it well for under $500 usd. My 2 cents.

    This is a great bike. I am sadden most people that are disabled do not have the means to afford this chair.
    When I saw this chair I was overwhelmed this is a chair for me , until I saw the price tag. Why is it that we in the USA &;Europe have only the high end chair to choose from.
    I admire what you are doing for the third world countries, giving individuals independence.
    Yet why is it you cannot find materials that would allow us to afford your product.

    I WAS excited when I saw tis because I've discussed with a buddy chair bound how expensive chairs are and they insurance doesn't often cover them. When I heard USA and Europe  high end buyer I figured $500 -800 but 3K and up screw that. Sadly great concept but it seems as if the greed of $$ over rode the desire for an affordable chair. Don't worry though a little time in the workshop and I can make one for nothing. If truly affordable I would have picked one up but naaah. Honestly if you could bring your price to truly ( AFFORDABLE ) under a grand say you'd most likely double or triple your sales and up your profits.

    Not a very smart invention Mr. MIT. You can't bench-press for 5km, you'll pass out after 200 meters. A smart invention is a power-chair over a hoverboard-style motorized transporter rechargeable by solar chargers. By the way, half of the disabled don't have strong or even working fingers.

    And now 6 years later, what happened to this wonder wheelchair ? My guess – huge failure. Ratcheting levers contraption to propel the chair is very silly, say the least. Its more expensive, complicated, heavier and according to real mechanics -slower. I think that guy just wanted a free trip to Africa.

    ive used a wheelchair like this before back when i was 16, im 25 now <_< it was a prototype, for someone called andy, i cant remember the name of the company he was running but the levers were not removeable but insted to put them away you push them all the way down and then they lock, and then on the wheel was a little flip i dont know how it exactly worked but it switched it from manual lever mode to hands on wheel mode, it was a bad chair design and nearly killed myself with it, then he refused to pay me for my work -.- so my dad threw the chair at him, and told him to fook off, altho at the time i was mixed feeling about it. it wasent a bad idea to me, then but now, i think honestly its not practical at all. gochairs or something <— not sure

    3K for the US is BS. They could import them flat and sell them as kits, Anyone can learn to weld or find someone who can, and mail order parts as needed, my guess is they already leased the market out.

    So Many Are Not Able To Use This Type Of Wheel Chair, We Need A Power Chair Usable Indoor And Out-Door Terrain. We Would Love To Get Outside Enjoy Life Too. There Are A Lot Of Very Low Income Disabled In The US, UK Including All Parts Of The World, Don't Forget Your Neighbor In Your Own Back Yard… I Believe In Helping All; But There Are So Many That Are Forgotten, Your Neighbor Right Here In The US Too…

    I hope your business goes out of business and you are judged before God. Everyone in America is not high end buyers. Most people needing this are on a disability income of around 1100.00 more or less a month. What you are saying you only cater to the 1% of America. Go back to my first sentence.

    Why doesn't MIT and the other mechanical engineering heavyweights lobby and support cheaper highend products for the American disabled community? Now that would REALLY be true innovation — affordable high end wheelchairs FOR ALL.

    And what if the arms can't move it? Disabled people who are in need to use a wheely do not all have powerful arms or can train them to be some day! I've two "frozen shoulders after several OPs and now l'd like to get a Wheely to go out alene to buy my things and to do my stuff! But all l got was a 18 kg – manual wheely and l just can puck it in my car to ask s.o.to drive me to the point l have to be to buy my weekly things. I'd like to be able to do it on myself! People who aren't disable often think – and they don't mean it bad – that we have to be content with little updates. BUT we only wanna do the things we did bevore or, if born disabled, what other people can do without thinking! If l go out l must clear all things bevore as: time to bring my wheely in/out of car, to have enough power to do so, place that all the stuff needs in my or other's car, to have enough money to give presents to all people helping me ( l love to give presents but if l only could walk on my own feet l just could use my feet and it were done. I allways have to say thank you for so many people, that l often think on myself that it feels as if l were a 2nd – class – human. Please and thank you are my most spoken words a day and most words l hear are: wait, not yet, perhaps next week or: ask another one. Or: NO. I only wanna life free and wheeled-bountd l'm not free in any way! So l need a wheely whichIS my legs whole day! I can't change my wheely twice or more a day depending on what l wanna do! There ARE wheelies who could be my legs but disabled people don't get the best to compensate my failing legs or muekles or s.th.else, we get the minimum that costs low and helps only very low . So, please, develop wheelies or functions to be abled to be built in OUR Wheelies, to be given to nearly everyone and not to cost in ilndia 200 SS and in the US 3000 SS and in Germany it can't be found or isn't to send! We don't wanna feel like an applicant! Nnoone of us is freely a diabled person, it wasn't our choice and it's not the credit of anyone that they can use their healthy bodies (l'm happy with that for you) and we don't !

My shoulders are "frozen shoulders" and they can't made being ok again my doctors told me. 2nd There is a big wheel in front. If l only hat one of them, l would be able to manage rough terrain! And 3rd the price: l've heard that here in Germany the gadget is so much more in kosts! There are about 2000€ to pay, that's 10 times more! 4th.: the man in the first film had a O2 – mask, the man at last didn't need any. Why? That isn't the same condition and so you can't compair this!!! That's not fair! Absollutely not!
