Scratch

Hello, Now that I have moved on from my Inmoov I have been itching for a project. I would really like something unique and I have been enjoying the design aspect of it. Since I never properly named my Inmoov I am starting with a name. It is Scratch. Because I am sure it will get it's share of dings and scratches but also because I am starting this design from scratch. A singe eye is where I will start. I wanted a gimbled eye that looked kinda cool. It needs to move in the X and Y direction. I wanted it to have some form of interactive feature that could be used to help emote. So a blinkiing iris type of eyelid it will be. I also wanted a camera and a neopixel ring in the eye.

So here we go;

The iris is open here. You can see the white ring houses the neopixel ring and the EZR camera is at the center. I tried some surface detailing to make it cool. At this point I think it is an eyepod!

Here you can see the servo arm that will actuate the iris. The camera is visible as is the servo that provides for Y elevation. It was quite the ordeal fitting all the functions in there.

This is the rear half. The servo is for the iris function. You can also see the features I put in to secure the Y servo.

I needed a way to traverse the eyepod and I was considering two eyes for some configurations. So I designed this cross mount. It uses 3D printer belts and printed pulleys. I needed the whole assembly to move extremely smoothly and the linkage arrangements I tried were too jerky. This moves really smoothly.

I am not quite sure where this is going. I was thinking maybe a replacement head for inmoov for people that want something a little different. Maybe it will be part of a walking robot, who knows. I'll post some more information and videos before too long.

I can't wait to see what the rest will look like.

Looks like a fun project Perry, nice work on the eyes. I'll be watching for your updates.

@Perry, Very nice work on the eyes, from the photos the print quality looks excellent!

The size looks really big given your hand in the photo as a reference? How big will be the head?

As others have said, watching for updates.

Again fantastic work!

Very cool looking, thanks for sharing Perry! Definitely watching for updates as well:)

Thanks all, I am having fun.

@cem each eye is 100mm in dia. I was thinking this should be an appropriate sized humanoid head for something the size of an inmoov.

It will be bigger than a human head. The way I am looking at this is funny. Inmoov is designed by humans to look mostly human. Mostly but not exact. I am seeing this from the side of an alien race! This design represents what the alien designed as a 3D printed robot to look mostly like them. It's making it fun.

@Perry that's a great idea using printer belts and printed pulleys. would you be willing to share the STL files for the pulleys, that could be most useful in Robot design. I have been working on a female Robot head and I think printer belts and pulleys would be very useful. the Head is normal human size but has the look of an android. :P

I am starting to get accustomed to the belt and pulleys. I use the 2GT standard. You can find a lot of stuff on Thingiverse or just design your own by looking up the parameters on Google. I did the latter.

Here is a quick vid showing some of the basic eye controls. Mostly a EZR servo touch pad. Have the blink function in there which rapidly closes and opens the iris

Se a few things to fix but holding up pretty good for now.
