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.

Are these files shared? I'd love to print one of these and have it on my desk!

#18  

Need a bit of cleanup then I will put them up on Thingiverse. I'll post a link here when done.

I can't wait to get these and show them off on The First Layer. Will these fit the InMoov head?

Sure if you increase inMoov's head size by about 3x... :)

It would be more of a whole head replacement that would fit on an inmoov. I am thinking of taking it that direction.

Or as Richard has said, one could build a 4 meter inmoov and put them in as is. That would be cool.

They look fantastic. I do think you should use some faster servos for the irises, or maybe change the lever system so the servos need to travel less to fully open/close the irises. For expression of emotion they may be fine, but the eye blinking is a little slow IMO. But great work!

Have you gotten any closer to publishing the design files on thingiverse for us yet? I'm super eager to 3d print this and use them for demoing vision recognition features.:D

Sorry, I have been too busy complaining about your pink sites lack of new content to create any new content of my own. JK and LOL. but I have a Christmas where I do not have to post new software updates for customers so maybe I will just sit down and finish it up. Every design has something ugly you want to hide.
