Re: Artifical Muscles - 17 years ago
Hi Victor, Oscillating pressure sounds promising, the whole thing could be more or less a closed system then, and placing all the machinery in a central place would be good. Here's a description on how to create air powered muscles, that are somewhat similar to that idea: . We could probably replicate much of it using an elastic and stiff polymer, although something fiber-like (bendable, butby zzorn - General
Re: Support material slump - 17 years ago
How about using water for support material? Build the object inside a watertight box / container, and add water after each layer to keep the water level at the current layer. It would have the advantage of very good cooling, which might maybe avoid the problems that arise from slow shrinkage during the build. The plastic is about the density of water, so it might be possible to do large overby zzorn - General
Re: Artifical Muscles - 17 years ago
RepRapped pneumatics sounds interesting. A neural network does indeed sound like the optimal controller for that kind of set up, it just needs some kind of feedback from the fingers (maybe touch sensors along them, should be easy to do with a conductive polymer and elastic cavities). Still, a pneumatic system needs some way to generate and control pressure. One simple way to generate the presby zzorn - General
Artifical Muscles - 17 years ago
Hello, I just recently ran across RepRap, looks like a very interesting project! Regarding the discussion about creating motors with the RepRap, one futuristic solution for that might be to use artificial muscles instead of electromagnetic rotating motors. Some materials contract when a current (or in some cases chemical) is applied to them. Some of these materials are polymers, and couldby zzorn - General
