Doesn't look as "smooth" as the OP video, but then he's just starting,
and has zero use of his legs, sooooooo......maybe some day!?!?

Interesting research and engineering, Leon. As I was reading I was relating
the pneumatic assist effect to a cuff-type wrist-wrap blood pressure meter
that uses a tiny pump to inflate a bladder in the wrist cuff.

These cuff-type BP meters are a bit larger than a Dick Tracy wrist radio,
but the pressure from the little pump applies considerable pressure in the
cuff.. and from just a couple of AAA batteries which last for many tests.

FWIW, larger bladders are used by fire/rescue teams for lifting heavy
objects and/or vehicles.

I knew of the bladders, big trucks use a type of bladder too for lift
axles and sometimes for the spring/suspension. I hadn't ever seen
something though that could pull quite like this.

I was curious if you could buy the PAM's (just a regular joe) and that
led me to this document, which is actually a slide show presentation:

They are rolling their own version to get custom specifications. On
page four they have a parts list consisting of clamps, nylon
sleeve, stop plug, rubber tube, and supply plug.
