Quite an interesting article... it gave me a good idea to work it with my kids.
Now that many want to draw teenagers attention to engineering and science.
It was some time ago now that I didn't heard about SMA or muscle wire... it sounds interesting and not only for robotics but... for some other unusual applications... I wonder what could we do with it?... perhaps some self adjusting glasses... or something alike. let's see what's in youtube about that...
Glad to have captured your interest. Let us know what you find on YouTube regarding its potential use. Funny, isn't it how something mentioned in an article can promote further innovation. I love this job!
