Hi I am fairly familiar with industrial robotics and automation as well as CNC Machining so I started a business called CNC Micro and I want to be able to show of my rapid prototyping skills to customers so I came up with a plan to make a fully functional Biped robot and I want everything to move from it ears to its toes and everything in between so I so far have built its head with Galvanized wire and solder. I am currently waiting to order 9g servos for ears eyes and lips as well as make its eyes.

Here is where I am at so far.

Jaw movement

Tongue Movement

The Idea is to be as complex as possible and sort of talk like us with mouth movement my original idea was to use a servo to actuate a bellow to simulate breathing and allow air to pass through a loose spring to simulate vocal cords but I scrapped that and went with the small speaker behind its tongue. I also am giving it a dog like head hoping it won't be so creepy aka uncanny valley.
Any one have any suggestions?
Also i would like to add if this works out like I want it to I feel it would be a cool open source robotics kit for anyone.

Ambitious project!
I might have some micro servos someplace, the big problem is that they have to be modified as those brushed trimpots always fail with time.
I had an idea to do this with larger servos originally intended for automotive use as a magnetic rotation system would have the advantage of single/multiturn with a single unit.

Small update I took a good part of the day making its shoulders and a part of its chest hoping I can find solder able servo horns for large scale that would make life easier for the shoulders simple linkages made from the galvanized wire won't be strong enough to lift the arms.

Here is another short video.

There is obviously a whole lot left not even mentioning figuring out what to use for a skin like latex foam or something and the molds. I now work 2 jobs and work on this at least 2hrs a day its so far been just a little bit over a week so I have come pretty far I think.

Thank you Conundrum I think all of the servos I use will be metal gear for the hopes of longevity for a prototype anyway. I also hope to look at A.I like a hardware/software Neural network.

Yeah, Movidius chips may be useful here.

Also worth looking into, repurposing 1080Ti graphics cards for DL.

Well I have so much to learn about AI do you mean Definition Logics?
Lol Deep Learning.
Movidius at $80 a stick hope 1or2 will do :)
Also Li Poly or 18650 I hope to keep low power but windshield wiper motors as servos might be power hungry.

Doing some work now, haven't managed to get any yet as everywhere is out of stock.

I did however get a Zero W, and in principle a large enough array of these might be enough for my needs.

HAHAHAH 5 nights at Chris' Place. HEHEH.

No but seriously, why would you want it to be a social robot? Why not an anti-social robot? I think that would be more fun, and probably more difficult to come up with a "sarcasm" subroutine.

Hah 5 nights at Chris's I feel because its for professional reasons it will be kind but there is no reason it can't be rude as well :) I how ever can't even imagine how to come up with personality yet but if I keep working towards the completion I hope it won't be long before I dig in to that side of the project and hopefully it won't be creepy as heck.

Here is an update on arms allot of Movement like the human arm I started making hands but they look stupid I need to start over on that.

Here is the album from photo bucket due to needing to upgrade my account? Greed. I can't third party share.

Personality,

Well, I figure you can break it down to statistics right?

You have words and phrases that are keys that are compared to some kind of scoring system, more positive response from positive inputs about the robot, and a less positive response for criticism

100 you look nice today oh thank you

-100 you're a puppet HHAHAHAH foolish human... you're a puppet too

so it could grade the input, and the FFT of the tone of the person and have a random (pseudo random) aggregate of responses.

But it's just a thought, not sure how I would program that either.

That's an awesome idea I have a bit more faith in this now.

So I am not sure if this has been covered on this forum but Lattepanda or Udoo X86 my plan is to use Linux so the Lattepanda is pretty much ruled out due to the strange Bios. Udoo X86 supports the good stuff and I'd like to use the fastest M.2 SSD I can find Hoping it can respond fast any suggestions? I figure X86/64 is important for Movidius.
