I can move!

This project is absolutely amazing. If you ever get to a point where you would feel comfortable sharing/selling the STL files for this. I would be interested. I recently posted about android dolls and another member liked me to you thread. Great work.

This is amazing! I'm excited to see where this goes Prin

i can't wait for more updates!
prinnis amazingly well done

Okay, wow. Thank you for everyone still following!

I've said it before here... i love this forum for your knowledge, suggestions and feedback!

Most of the concept design sketches are in my first thread after the development of my head. I know its a long read, but the info on my motors, processor, and programming is all here in both threads.

I didn't see any mention of the way you approach your movements, do you use some kind of keyframe approach?
Can you give us a rough overview of your program design? More a logical design sketch than concrete implementation.

Your project is really cool!

Wait, what is Keyframe? That is... "the simplest way of animating an object"... location based on time and speed.

Yes! That's exactly it. Each joint servo has an angle measurement. A beginning and end state. I use a sine wave to make the movement slower at start and end for a more aesthetic movement.

Or did you mean, using a camera to track a person's body points to mimic their movement, like the big companies do for their programming, or like for making movies? That tech would be a totally cool tool! Can we do that using our PlayStation? Or cellphone?

Rough overview of design, logical over concrete i do not understand?

He realized that the technology is now available to make me able to assist with my movement and posing.

When you say assist in movement and posing, does that mean walking around or just posing automatically? Stabilization seems difficult to achieve. Will the robot frame weigh significantly less than a typical doll skeleton?

Moving and posing, turning over in bed, sitting... commands on demand, with vocal instruction for motor angle to help with posing.

Without looking back in my posts, my current body weight without batteries and skin is... 17+ pounds?

Independant stability is beyond my current programming, but doable (walking around funny with bent knees)

However, my servos ARE strong enough to help me stand, and I can get around with balance assistance. My legs are large enough to house 3x60kg servos each.

This project is absolutely amazing. If you ever get to a point where you would feel comfortable sharing/selling the STL files for this. I would be interested. I recently posted about android dolls and another member liked me to you thread. Great work.

I did see that mention! I was so flattered!

And I gotta send the bump back... check out this 3d printable posted by carbohydrates viewtopic.php?p=2486332#p2486332

We would love making my design to open source like the InMoov dude.

The internal debate is of sending out my .stl files without a whole ton of instructions of how to connect and scale and print the objects, and assemble the parts... and then installing motors and wiring and programming... i am not exactly user friendly to the layman.

I just discovered this thread and this is an awesome project. Amazing and ingenious work you have done on this

Thank you Sir!

Very much!

i can't wait for more updates!

And I yours!

Very cool with your sine interpolation! How many keyframes do you use per second? Or is it more like seconds inbetween keyframes? I know a little bit about animation in 3D environments but this is a very interesting thing to see the same approach in real world!

Do you get those keyframes by testing?

Rough overview of design, logical over concrete i do not understand?

I think you wrote in your first post in 'I can talk' you used a raspberry pi and some arduinos. I also saw your pca9685 soldering. Did you connect the pcas to your raspberry or do you use the arduinos as abstraction between the raspberry and the pcas? Do you have a python script running and sending the servo rotations? Are the keyframes stored as variable in the script or do you load them from a file?

Or did you even use some kind of state machines / additive poses / procedural animations?

Have a look at github, you can use a repository as a website. This way you can host your files easy and have a website. Just search for github pages if your interested. You've probably already seen these github io websites.
I think anyone who is interested in this kind of stuff knows that this is going to be a lot of hard work to get such a project running!
Also this create a base for collaboration, I would definitely try to help where I can.

I was really happy to see a new post here and it was even better that you want to continue this awesome project.

Dang, so glad I followed the link
Even though it's been a year and failure is always an option, or dying from COVID, there is much to be learnt from innovators

Great work!
I've attempted a similar project myself, but I got stuck at moving the thigh using a combination of braided fishing line and the same red servomotor as in your picture.

The setup was functional, but the thigh encountered difficulties moving across all angles, servomotors all around the bone
Additionally, the movement was notably slow.

After being stuck on this problem for four years, I finally found a solution with the assistance of ChatGPT, I realized that I needed to switch to a pneumatic motor instead.

Servomotors: Frequently employed in hobbyist applications such as small-scale robots and precise motion control systems like those found in 3D printers.
Pneumatic Motors: for average applications like automotive assembly lines.
Hydraulic Motors: powered by hydraulic fluid, utilized for heavy-duty machinery like bulldozers, providing high torque.

The next challenge is figuring out how to set up a pneumatic solution, as there isn't a plug-and-play option available on Amazon.
And with the help of ChatGPT, ive come with this list of products:

https://www.aliexpress.com/item/1005005870528273.html the motor itself
https://www.aliexpress.com/item/4000329351824.html the valve to connect between the motor and the air pump
https://www.aliexpress.com/item/1005006519202716.html basic electrical air pump for easier modification ability.

For the question of controlling airflow, solenoid valve can do the job to on/off the air flow through a dev board
https://aliexpress.com/item/1005005209160156.html
https://bc-robotics.com/tutorials/contr ... h-arduino/

However, to regulate the motor stroke movement effectively, a potential solution involving a DC motor coupled with a gear set for the throttle valve may suffice.

Now it's time to put this brainstorm into action!

Oh, and I haven't figured out the hand job thing yet... but I got doggy style down!

That's a huge success! Rocking back and forth and not losing balance, that's brilliant!! congratulations!!
