This has to be the most impressive LEGO pneumatic device I have ever seen. Max Shepherd (no relation that I know of [but I wish he were]) built this massive, beautiful work of art. The robotic hand has enough degrees of to make you believe it's a real hand. The movements are slow, but realistic. I think he would need an industrial air compressor to have enough air to run all the cylinders.
Very nice, Max, thanks for sharing with me.
If there were one thing that I would suggest, it would be to incorporate a NXT with a HiTechnic IRLink and use this system I built to control the movements. And of course, a HUGE air compressor..
