My Advanced Realistic Humanoid Robots Project

Artbyrobot · 02-20-2025, 01:12 AM

I'm trying to take on the impossible: to create robots that pass for human in appearance and movement! I want them to do useful work too! Also yes, I probably watch too many movies

I hope to post my updates here and discuss what I'm learning and get some feedback and ideas from the community here so I tap into the brain power of my neighbors to assist me!

Here's the CAD for the torso:

Sorry but you will probably need a few decades more than you will live (or that your program will run) and several, several more IQ points.
Maybe ChatGPT will start a forum for you. As for now think you need more diagram lines.

I hear you on that and it is my fear. Life is scary short I keep realizing more and more. And perhaps I do need alot more IQ points, however, if we add my handful of points to other forum members points perhaps we can scrape together enough collective points to push through?

Also yes, I need WAY more diagram lines haha

So you are thinking about filling the body with a lot of small hydraulic (or air) cylinders? for more accurate movement.

Then there is no room or need for skeleton shape(s). Only an inner rod structure or wire mesh.

I can see what you mean but no those are actually brushless dc motors instead of hydraulic/air cylinders. They will act like winches reeling in fishing line which then moves the joints. Kind of like a Jeep winch and a bike brakes cable merged in concept. Downgearing will be by way of pulleys so I get silent actuation that way. Think of industrial cranes downgearing with pulleys. That same concept.

As far as no need for skeleton shape, that is true. You can go with rod structure or skeleton and I plan to try both methods out in different builds. I can only speculate on which is better. Both have pros and cons.

OK Clear.

Big project. Goodluck with the overall design.

Here's some bone sculpting and fiberglassing in progress.

Here's artificial ligaments made of spandex I put on with adhesive transfer tape and sewed seams

@Halcyon thanks man!

Here's the hand sewn together with spandex and adhesive transfer taped down in spots.

Sewed Spandex as skin layers is clever solution.

An arm with hand fully wired will already take a lot of hours.
Nice work.

Thanks Halcyon. But actually the spandex is the ligament substitute and the skin layer will go over a exoskeleton mesh scaffolding that acts as the muscle definition layer under the skin and the skin will be silicone with realistic tone and texturing for realism.
