Hi everybody! Just a simple post to share a nice video I found on youtube … 🙂
Last week I was surfing the web looking for potentially awesome ideas for my PhD project… well, actually I just needed a list of mechanical mechanisms and configurations in order to evaluate new design proposals for the knee prosthesis I am currently working on. As most of you will know, for sure, the step google research -> silly video is more or less immediate 😉
Most of the times the silly video you find has nothing to do with what you were looking for. Most of the times you watch it anyway, since “it only takes 2:35 minutes …” 🙂 and in this magic way, each day, dozens and dozens of hours are wasted by PhD students all over the world.
This time I was lucky! I found a very simple video, but actually it’s a really nice one! The user says it’s part of a “work by Ralph Steiner” … I don’t know anything about that, but the mechanisms that it shows are really amazing. Some of them have such strange shapes (I mean, the pieces that move are shaped in a bizarre way!) that you would bet the whole system won’t ever be able to move and next… the result is simply wonderful!
So simple + so strange = an amazing precise and regular motion!
Ah, by the way… finally the structure I adopted for my knee prosthesis is a particular screw-nut configuration 😉
