Depends on the application. There are several books that describe its
use in robotics. For example, look for the Stiquito books. The books
describe the construction of a small walking robot. It's also discussed
in general terms in both of my "Bonanza" books...this stuff has been
around for a while. I started playing with it in 1985.
The issues with "muscle wire" (that's a tradename by Mondo-Tronics; the
material is generically known as shape memory alloy) are: termination
and recycle time. If you can work out these issues for your specific
application it might be a useful material for you.
