If you increase the precision to 1000 or so it works a lot faster. I've just started experimenting with it.

Re: Artificial muscle

The other idea for heating the threads was to embed platinum particles into them and then allow methanol vapor to flow over the threads when heating was required. Surely some of the vapor is going to be wasted if you do that. However the energy density would be far in excess of what a rechargeable l...

Re: Streaming audio

I want to write some ham radio software to decode PSK31. I kinda want to write it in Java for portability. However that would mean spending a considerable amount of time doing a JavaFX GUI. The other option is a quick piece of code using FB. Unfortunately /dev/dsp is being removed from the Linux ker...

Re: Artificial muscle

It could reduce the cost of mechatronics down to a very low level. A few cent per actuator. I'll definitely give it a try at some stage. There are a number of options for heating the twisted thread besides electrical resistance heating. I guess you could incorporate ferromagnetic particles in the th...

I guess a few people use FB for robotics and would be interested in the latest work on artificial muscles:
