great vid just a quick question have printed and wired everthing but get no movement on any servo any ldeas
Started coding for running with a pi pico, it used to be controlled with two pots, but I'm working on a website. kzread.info/dash/bejne/hquT286xlK2ahag.htmlsi=lCGDK_DIhJgJdQVS
Have you considered using electromyography sensors on the arm to control the hand? You could record the electric response from the muscles in your forearm, combined with the motion capture data to train an AI model to predict the hand position from the EMG signal alone.
Thanks man !! :)
Lookin good, Will! Love the beard!
Brilliant work! I know people in the puppet community would 100% buy finished versions of this. I also think there is a version of this that is rod controlled, no servos required. Not a cable, a solid rod. The rod is pushed up and down, and the eyes move up and down, this fits in the neck. But left to right? Solved by the rod controlling that via being rotated left and right. Horns, like on a servo, attach to the eyes via a linkage system etc. I know puppet people like big eyes, that are sometimes more than 50% out of the head. If the eyes are held in place by rubber bands the eyes can stick out further, and the rod mech doesn't need to have a middle axis because the sphere eyes are being pulled into a socket, that acts like a ball bearing, creating the axis. Just putting this into your head....
quieter musicccccccc but nice one
Hello ! Great job! Can I buy a PCB from you?
In the 3D printing/STLs directory there are 43 items. Do all of these need to be printed to make the eyes?
Great design. Is it me or is the link to the PCB not working?
Ah I probably need to upload the Gerber to JLC? But how do I populate it?
Can you provide code of your previous project aurdiuno based eye mechanism kzread.info/dash/bejne/eKiom8dxqNGxdZc.htmlsi=EL6lA9KkkDSy5Ogm
Can you provide the code of servo.motor
7 years! An eternity man! NOW you understand why Chinese R&Ds employ 50+ engineers and 7 world-class PhDs on ONE PROJECT like this one, in order to achieve way more than you did in JUST 3 MONTHS! Being lonely is really a pretentious, irrealistic choice and definitely an inefficient IDEA! Poor man...
honestly, rather than printing out and meticulously figuring out a filament "gripper" paw pad, you could just pop down to a hardware store, get some silicone caulking and drip a bit or pinch some onto the bottom and voila, grip achieved. the advantage of this would be absolute rapid prototyping as you can literally just scrape it off and start again, not to mention filament costs and time designing, and my personal opinion-it's just fun to be more physically involved in creation sometimes, add a human element every now and again, ya feel?
Find mass produced ready made cheap eyes and remove electronics and make it a hand/finger moving puppet and it's an amazing toy
Now anyway to remove all electronics? I know it will limit its movements but with a couple 3d printable knobs or levers, we coule have this thing be an incredible battery-free toy that could even attach to many adapters , one of them could be a long stick that let's you move the eyes from behind a cloth or wall or under a table, so you can puppet this thing manually with some manual pupetter marionette style animatronic hand tools whatever those are lol im sure that's a whole adventure for someone else to try
Can you make it use self sealing stem bolts? I have so many lying around
Thank you so much. I think it's time for a universal 3d printable fastener and ai to help us redesign models for 3dprintables latched and pins etc... but yeah maybe we can make a universal 3d printable fastener or even a metal fastener that's the ultimate screw we can make in bulk for 3d printers or use something already ready to buy like self sealing stem.bolts
When you have circuit board 2.0, can you please offer it for sale. I would love to buy one. Could you design this as single eye? I have a model i need to space the eyes out on. This would make my life so much easier.
Anyone else having trouble finding the pcb?
Is there a way to use the parts you selected with jlcpcb? I try to use the ZIP at jlcpcb and it says: "Filenames cannot contain special characters or the following words【eval,copy,convert,confirm,Copy】" edit: Im going to try to use PCBWay instead
Thanks for showing all of these tips and tricks for animatronics, I believe you have the best educational content in youtube and the website you have is awesome. Thanks again I really appreciate the effort you put on these.
When do you think you’ll release the files for the controller?
I think I need to do some work before I’m happy with that one - but in the meantime I’m pretty happy with my original design - nilheim-mechatronics.notion.site/Simple-Controller-301224f539e245cfa63d29b218b5b366 (it’s not all snap-fit though!)
Just found your videos. I love hobbyist robotics. What to build first?
Wow! ❤
Brilliantly thorough as always!
Awesome work!
I hated the design of prosthetics back in the 1980s when I was in my senior high class and so I designed a realistic almost natural range of motion. The muscle components were to be made with silicone, electromagnetic flex impulse, signal from the brain feeds electromagnetic fibers embedded in the artificial muscle flesh, with a hydraulic system also embedded that would resemble veins, probably, with artificial skin and that would allow the flexor tensor back and forth action and make it look very realistically normal or biological I should say maybe and ferro- Magnetic fluid was my first thought for the hydraulic action, one reason for this is because it's no Motors it is a completely different idea and so you would want the Bulge of a bicep because that hydraulic action would cause that especially with a design of your channels in the muscles and if you design the skeletal features and ligaments and tendons it would be very biologically realistic especially with any touch sense. You could combine several processes and use far lower power. I want to be able to help refine a design of and operation of the redesign of my doable miracle. No no motors. Cmuscle so that you can cover it with skin or gloves or whatever and it is basically barely noticeable that they would be simulating by a hands my nephew lost his hands and his feet to being bit by a flea a year ago and now I'm desperate not just interested to help him so if I can help you then I will help him and others that desperately need it simulated biological process with artificial components. That's what I would call it.
WARNING: For anyone changing from the compact design to this. The base plate does not have enough space to fit the MG90S servos that are vertical on the sides, only an SG90 will fit. It does look there should be space to cut the base a bit and make room. Great design otherwise!
@will cogley You can simplify your design by using a thumbstick that has center click
peak
Really really ace work, I guess it's time I start filming some creature features!!
Another cost-down/simplification could be to allow for the MCU to be soldered instead of putting the Arduino on. With a bit of luck the JLC library does have the same or a 100% compatible clone. You probably do not need most of the other components on the Arduino anyways.
Excellent results! ....May be I will give it a try! What layer resolution / infill ?
For another challenge you could try minimising the amount of servos? I'm not an engineer so I have no idea what I'm talking about, but 5 servos seem redundant for 3 types of movement
Good to know how good terminato's hand is going to be. But as y'all know ultimately T-s will just control humans bodies by NANOs so it's just intermediate things!
"The best part is no part", I will be studying this design to see if I can print smaller version on a resin printer.
I wonder if Hueforge could be used to color the eyes.
Awesome work! Just print in some cable management for perfection
Thanks a lot! It’s funny that I just printed the old version last week 😂
Very nice project, it makes me want to see it linked to an ia which, for example, would follow the person in the room with its eyes and which could be questioned at any time (funny and very practical for me who works in a studio alone, for example).
Now you gotta implant cameras and make a really strange ring doorbell
Love your work. Thanks for sharing. Are your cads editable?
This is awesome.
Had a led inside the eye , and you could had "Goaul'd " effect or that kind of scaring effect 😂👍👍👍
Please add eyelashes 😂
Started out just trying to google "Child's Play behind the scenes" and it's come to this...
Totally forgot about this project might need to do this to make some overly realistic furbies...
Hmm, having trouble accessing the link to the PCB for JLPCB. Can you check the link there?
Just saw your reply about uploading the file to PCBWay from the ZIP file. Thanks!
Not sure what I'm doing when It comes to ordering (preferably populated) PCB's any guidance?
@@davereynoldsorama I'm actually having some issues with the component placement in the supplied files. Normally, you'd download the SupportPack files in the link, and in JLPCB, you'd upload the zip GERBER file (you have to rename it from it's current name). Then, check the box for PCB assembly, and you'd click continue and upload the BOM and CPL .csv files. But when doing this, the components aren't lining up correctly.
Just wanted to express my gratitude to you. I've been wanting to start into animatronics for quite a bit and have kept putting it off because it was overwhelming to find a starting point. Thank you for putting this together and for making all of your projects so accessible!
