WheelchairDriver

Hello we are fourth year high school engineering students and we are working on a final project for our engineering class to improve a manual wheelchair. We would greatly appreciate it if you would be willing to take a quick survey for us so we could gather information we need in order to further our research. We thank you in advance.

Again?

Why bother. You all ignore this, never return, and then build something we dont want to do something we didnt ask for like climb steps...

And who wants an 'improved' manual wheelchair anyway? Especially from the survey form, its clear that 'anti-rollback' is their proposed project...

Isn't the powered chair exactly that ! An improved manual wheelchair ? And the BM model adjusted for individual preferences, and of course the LiFePO4 battery system. They are the perfect Paraplegic chair as "The Burgerman" created it, and to make it better for more complex needs users this can be adjusted for CG and balance to suit their purposes.

However, knock yourself out trying to improve those ancient manual chairs.

Of course the third world have a need for manual chairs. But mostly cost/reliability related.

Actually the folks at MIT have some pretty interesting 3rd world grade chairs - long and heavy, but using a lever drive system, standard generic bicycle parts, and low-tech design / build techniques. I've given one a short test ride and for what it is, it isn't bad... They also have a version for the US users that is a rough trail off-road chair....

IMHO the biggest thing I don't like about it is that it has a 'tricycle' layout with a long front end, which makes it awkward, but allows a large diameter front caster, that is more suitable for rough riding....
