This project is an upgraded version of my previous design, a highly compact and robust animatronic eye mechanism which uses 3D printed components and an Arduino microcontroller. If you are able to get hold of servo ball-links and pushrods, and are reasonably competent with 3D printing, this is the eye mechanism project I'd recommend most!

every time i see you make something new or make a previous creation better, it inspires me to try to make my own creations as good as a can and that there always is a better way to do something than the way i am doing it already. keep doing great things.

Try to make a eye tracking mechanism, with cameras integred inside each eyeball

@SinanAkkoyun 4 года назад

Motion blur would be too high

@Dan-The-Orange 4 года назад

Absolutely possible. You could even use the same code in one of James Bruton's videos. I might try this as I actually have everything needed at home.

@SinanAkkoyun 4 года назад

@@Dan-The-Orange I am sorry, didn't mean to discourage or claim it was not possible. I can imagine it would work absolutely flawlessly if the code is well thought out. Like for example add an eye boundary (camera space) in which the tracked object can stay and the eye stays where it is. If it is outside this box wait x milliseconds and retarget, which would overcome lmitations of cheap camera modules (at high speed). I did a false claim with the motion blur, lol.

@SinanAkkoyun 4 года назад

@Waltkat 4 года назад

Very nice design, but the next iteration of this design should be the separation of movement between the two eye balls and lids to allow for a much wider variety of eye movements such as winking and going cross-eyed. One of my favorites things to creep people out is to look left then cross-eyed then right and back the other way.

@ivanwilliams6158 4 года назад

I'm tempted to try and modify this design to make it work for costuming, with eye tracking or a controller, depending on what ends up being plausible. Really brilliant design! I'm looking forward to the controller and being inspired by all your future videos!

@WillCogley 4 года назад

Please do! I'd love to see it in a costume.

@ivanwilliams6158 4 года назад

@@WillCogley I'll certainly try then! :D Also do you think that it would be possible to move the mechanism to be above/below/both in relation to the eyes rather than behind? I would have to learn a lot more about the software necessary for such modifications, but i'm wondering if you think that's worth pursuing?

@WillCogley 4 года назад

@Omegryth Yeah that would definitely be possible. One thing I'm hoping to try soon is having a cable mechanism between the eyes and the motors so you could hide the motors anywhere you want.

I'd recommend printing everything 5 or 10% larger. I had to do alot of post print clean up and use a 2mm tap and die to open the holes up more to fit everything.

@drakkartwentyd1389 3 года назад

good design however to fit it inside a head it could be made much smaller by spinning the x and y servos by 90 degrees and opposing them , removing the eylid servos from the rear and placing them on top you would gain a good 25 to 30 mm that way, also a great addition would be a camera mounted in one of the eyes

Can we make a program who these Servo-motor play in loop to look like natural eyes without our action ? Or move independently ? Its difficult for me to understand how the program acts on the eye movement.

@ragetist 7 месяцев назад

First of all, amazing project! I was wondering if the eyes support against the lids when they move and if it's possible to make the distance between eyes and servos shorter without messing the movement? I'd like to make a single eye, lidless version but the use I have in mind would need it to be relatively low depth 🤔

@pixelatedgames8068 Год назад

How easily could a project like this be scaled up? I intend to make a slightly larger version at some point, however I don’t know much about the mechanics of scaling it up and how that will affect how it works or if I will run into any other problems.

@ringovoid 3 года назад

If I wanna make bigger eyes do i have to change something else then or does the mechanics work on bigger eyes too? If not, what do i have to change and to what scale? The size of the eyes im about to do is probably 4-6 times bigger!

@chloskyskies4399 2 года назад

Another possible idea ? : Making eyelid part more like a wire skeleton or a mesh(?) So the lids seem less thick. Thoughts?

I made it and put smd rgb led in each eye. Had to remake the two eyes so there is a hole in the middle of them the printed with clear pla to holed the led and fill in the rest of the eye. for now every forth blink the eye will show a different color. looks wild!

This is such a beatiful build! I am desperate to get it working for me, so was going to ask for help. I have printed, built and wired both the controller and the servos, but the area i am struggling is the Ardino side of things. I have uploaded the coding and keep getting exit errors?? (Never used Ardino before) Is there a complete file that i can can download or copy and paste it to the software for all the aspects needed? (Servo drivers, controller and joystick/momentary switch) I am trying to embrace this new method of animatronics as previously i have always used RC transmitters and relievers. Any help would be greatly appreciated.

I know someone has built it successfully in resin, they said the only issue was that they had to print the eyelids at 101%, and make the eyelid holder a little bigger too.

@FinepixF30 Год назад

3:38 Just wondering why if the 2 eyeballs move parallel to each other not use the same pair of servos to move both eyes similar to what is done with the eye lids, this will save money on 2 extra servos and less wiring to worry about. this will require the 2 servos for X and Y motion of the eyeballs to be moved to the centre.

@springplus300 4 года назад

Couldn't this be done with half the servos? Are the redundant servos a question of wanting more options in the long run (upper and lower eyelids moving separately, ability to go "cross-eyed" etc.), or are they there for the sake of power?
