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.
