Presently embarking upon a project to create a 6 inch diameter Wheatly figure from Portal 2.
I didn’t play the game much, but my daughter is in love with it, and I wanted to start a project that we could share.
- Raspberry Pi as a show controller
- Pan and tilt eye within the face
- oLED eye for animation and personality
- Separately articulated eyelids
- “face” disk has pan, tilt, and limited roll
- Articulated handlebar eyebrow things
So far, so good. In CAD land, everything fits.
This is Wheatley
Interior view showing the different articulations
inside the head there is a gimbal rocker arm that supports the face and articulates it in the roll, pitch and yaw axis’ of motion. A triad of servos affixed to the base do this with some cross talk which I hope to program out.
Eyelids, which share the axis of the face’s tilt articulation, are fully open-able, and each lid can close about 90% of the way.
Rear view of the eye gimbal. Rather than share the same axis as the face, I decidedd to move the eye’s rotational axis’ forward to allow the face to emote better.
“Eyebrow” handlebar detailing has begun. Articulating this axis is potentially difficult.
Some work on external cosmetics that does not affect functioning has begun as well.
