Testing with <20ml of water 💧 . Good results!. The next muscles will be smaller and faster.

I'm trying out something different. Blending soft robotic muscles with a traditional cable-drive system. What could possibly go wrong?. The best part is that the test unit worked. Now, to figure out scaling. .

Seeing this third MYO-FAB gives me some ideas. I might reconfigure this to be a vertical device for winding multiple soft muscles concurrently. The lead screws will remain for the Z axis for now, with the others being swapped for belt drives. CoreXY muscle fabricator?

Working on some miniaturized soft valves right now.

Another consideration: the way the mold is printed has an effect. Aligning the Z seam of the mold creates a noticeable mold line on the bladder (a weak point). New molds will use random seam alignment.
The current muscle bladder design works fine, but I want to get MORE POWER and CONTRACTION (~35-40%) out of them. I'm redesigning the molds to create more radially-expansive bladders, while constraining forward expansion. Putting the current batch on hold to save on resources.

Another batch of muscle bladders is ready for assembly. Should have a nice set of muscles complete by tomorrow.

RT @Xaraphim: seriously , why don’t we put more research into fluidic motors that mimic human tendons and muscles for humanoid robotics.

Successful first test of our contracting fluid-driven artificial muscles. I've got several more small ones to build for the hands, and then I'm cooking up some BIG ones for the arm. 🦾

Contracting muscles are coming together nicely!

Testing the smallest bladder first. Works very well, with no leaks! Off-the-shelf barbed fittings are used for connecting to supply lines.
Just finished casting some fluid bladders for contracting muscles I'll be testing out. They turned out quite well.
