Though the TefTek has driven castors, I have to agree with
Burgerman. Whichever way up I've added the numbers, a FWD
chair does not come out a better idea than the RWD design.
The ONLY function a FWD has that is superior to a RWD is the
ability to twist around tight corners in restricted spaces.
Ok for a lightweight in-the-home chair if you live in some
crowded council accomodation, but thats about all. (You
STILL have the problem of not knowing quite where your
castor wheels are too. Oops!)
The weight distribution on a FWD chair should have been
enough for the design to never have been considered for
anything else IMO.

They dont have steered castors!
They try to get over the natural instability of a vehicle with castors on
the rear by gearing the drive wheels together so that the thing tries to
travel in a straight line. Physics dictates that it will still "want" to
turn around and go backwards - moreso the faster you go - but the locked
diff effect prevents it, so no fishtailing. If it went fast enough however
it would still spin around and try to put the castors first! And its L O N
G . . .

FWD chairs are a nightmare, like driving a forklift or a harvester,
they're slow, because if they go to fast they become unstable, if you
stop to quick while going down hill they will tip forward.
Check out the Pride Blast or Vibe chairs or the Quickie 646SE or 222SE,
the Magic Mobility Frontier, there are lots to choose from.

That's what i thought, single motor driving the front wheels through a
diff with the powered casters steering.

Thats a bit unusual though, as most FWD chairs are just a
reversed RWD with drive-wheel steering, like a track laying
vehicle, the castors only there to keep bits from dragging
on the ground. ;\

The TefTek chair is the only one I've ever seen with active steering
from the casters, i guess it would overcome the fishtailing effect FWD
chairs have at speed, but your still stuck with tipping forward problem.

You are all mistaken because of the dodgy wording on the website.
Teftec chairs do not use steerable or powered casters.
They are conventional castors, stuck way out back ready to run into anything
available as they swing left and right behind you. The "improved" steering
comes from the fact that they have a different type of gearbox and drive
system that gears the drive wheels together. They can only rotate at the
correct speed in relation to each other, when traveling straight or while
turning. This means less fishtailing.
This is ok at low speeds and good surfaces where the grip from the tyres is
enough for the thing to remain stable in spite of its natural will to turn
around and face the other way. At higher speeds, or where grip is lacking
this method of defeating physics fails dismally as you go out of control...
As for rockets and jet engines - that would only be "safe" on a chair that
uses castors on the front or with proper steering wheels on the front.
Unless you count thrust 2 which uses rear wheel steering sucessfully only
because of naturally stable aerodynamics (big fin) at speed and computer
control, and extreme length wheelbase.

Cant you run some emulation software?
I can run mac stuff should I want on windows this way although its slower?
Mike-UK
Phil, if you're running Mac OS-X, it is based closely on
FreeBSD and may accept Linux compatibility stuff, which
means that you could then run something like WINE with
Windows running on/in/under that...
Or you could just hack off a partition and install a Linux
OS with WINE as a dual-boot option.
Hmmm... come to think of it, wasn't there a version of
WindBlows for installing on a Mac? (Like anybody needs
another huge security hole, right? ;)

You are indeed right Burgerman, i just went and had another look at

is a front-wheel-driven transmission-steered powered wheelchair"

Always the best way.
From what you've said about your poota experience, I think
you could be right about this as the shift from WindBlows to
something a tad better equipped, such as OS-X/Linux/etc. can
involve quite a steep learning curve, due to the HUGE range
of configurable options available. Its kinda like swapping a
dealer-serviced Honda Civic for a full A-Team workshop. ;)

Probably negative market reactions as people stopped and
said "You can do WHAT on the internet!?!"
The idea of the old pre-internet phone book was that it was
hardly worth burning out your eyes trying to find out
somebody's address if you only had their phone number. The
problem now is that the protection of anonymity has not been
updated to protect people's privacy from corporate internet
exploitation of computerised and minable data-bases. All
that data many would rather not be available to all,
available at a single mousing, and now they even provide
maps you can print out to show exactly where someone is,
arial photos to show you what the area looks like, and now
this thingy Burgerman has, whatever it does.
Good job we don't piss each other off too much huh? 8\
Maybe we should start renting out our roof space for
adverts?
This idea of course is my own copyrighted idea, as are all
derivatives of using visible domestic areas for the purpose
of arial advertising, including TV rights to all shows and
productions examining or otherwise featuring them. Apply for
details on deploying it. :)
