Pumpkin-headed desk robot mirrors an AI coding agent

The detail that caught me off guard: this little pumpkin-headed desk robot is not just decoration. It mirrors what an AI coding agent is doing in real time, reading, typing, thinking, and celebrating when the job is done. For Halloween it wears a carved pumpkin head with two small screens behind the eye sockets showing blinking cartoon eyes.



The build itself is impressive. Every model was handcrafted in Fusion 360, and the orange pumpkin parts came off an FDM printer inside an insulated enclosure tent, with a time-lapse showing the filament going down layer by layer. Assembly looks fiddly in the best way: tweezers and a pen-shaped cordless precision screwdriver, plus jumper wires in black, green, yellow and blue running behind the printed parts. The maker also moved to smaller servos, which reshaped the design considerably, and the model supports several servo variants.



The Halloween set dressing is my favorite part. There is a cauldron with glowing orange liquid, an illuminated lantern, small orange pumpkins on the wooden desk, and a front faceplate carrying a winged gear emblem with the letters AI. The articulated black arms let the robot tap the miniature keyboard when code appears and pause to turn its head, all in sync with the coding interface.



One trade-off worth knowing: the original 0.9 inch OLED was an uncommon part, so the maker swapped in a standard, widely available display, and since that panel is physically larger the head grew a bit. The maker later optimized for ease of building rather than size. Everything is open source, from CAD files and printable models to electronics and code, with a getting-started guide in the repository, and it runs off a regular power bank. The open question: what character or accessory comes next?


Swapping the rare 0.9 inch OLED for a widely available panel seems like a smart call to me. It did make the head a bit larger, but the maker then optimized the design for easy building over compact size, and a standard part should be far easier for anyone replicating this to source. Practicality winning over miniaturization feels right for a project meant to be remixed.

I am curious how the pumpkin head is mounted. The CAD work included a shell plus mounting frames, so are those frames printed separately and screwed into the servo arrangement, or does the shell clip on over the existing head? And do the two eye screens sit behind the carved sockets or flush with them?

A DJ version seems like the obvious next mod. The maker has said the current servo configuration should handle it, so spinning records while bobbing the head to a beat looks achievable without changing the servos. I would print a tiny deck with a record and a mixer to sit on the desk where the cauldron is now, keeping the lantern as stage lighting.
