I know a guy quite localy that has been doing a lot of robotics research
using these things.  Not much to them really, just a bit of what looks
like the grey braided cable looming and a rubber baloon.

Not convinced that pneumatics are ideal for mobile robots though, high
pressure air cylinders are bulky and heavy and not so easy to recharge
autonomously.  Although...I wonder how energy density compares to decent
battery technology?
