Polly the Cuddlefish (2.0)

Tell us the story of your project: 

Cephalopods, fur, and things that move that wouldn't normally: why not combine these into a furry animatronic cuttlefish-slug mostrosity?

Polly the cuddlefish was an idea that we built in 2018 for Maker Faire, and wandered around with until the servo broke and we replaced the servo with fishing lines so we can puppet the arms.

This year we decided to go all fancy and actually try to make a more polished version of a cuddly, fluffy, glowy land-based cuttlefish that would be an abomination if it were real.

How-to: 

Build a clay maquette with foil and modeling clay, then covered it in plastic wrap and tape to cut the tape into a rough pattern for the head, the body, and one arm.

Cut out the fabric pieces using the pattern, then sew the pieces together adding zippers to the body to access the plastic internals/electronics.

Paint the safety eyes and coat the eyes with resin.

Use the maquette to make a 3D scan of the body at Tan's, and 3D model the plastic body arms.

Use thermo-mold plastic to create a head/mount for the servo.

Attached the arms to the head and wired arms to the servo with the fishing line.

Glue components to the body.

Teaser: 
What if cuttlefish were land-based like their sluggy distant cousins? Except slower (immobile in this case) and (somehow) furry?
Aha! moment: 
UV resin cures a lot faster than polyester resin when adding depth to the eyes.Having a metal-geared servo means that Polly is less likely to strip the gears.Making arm segments that don't have hinge joints means smoother motion.
Uh-oh! moment: 
3D model/UV unwrap to generate the pattern for the exterior: The model was too complex to produce undistorted seams so we had to use a maquette to create a pattern3D model of the internals: the organic shape of the body is a serious challenge for new 3D modelers and we had to outsource to an actual 3D modeler (Tan of Tan's 3D Hub).
