RoboDuckBuild

Is it walking yet?

Not yet.

Every PLA part is printed; only the TPU soles and beak edges are left. The servos are still on pre-order, so for now the head is the busy end: the round screen and the camera sit in the new face, and a bench stand is ready to run the head on its own.

18 of 20 plates printed, about 39 of 41 hours.

Feetech HD-1910 servos: 16 on order.

  • Still to make
  • Printed or in handFitted to the robot

Next: Print the TPU soles and beak edges, then wait for the servos: OpenELAB expected to restock about 23 October.

From the diary

Every entry
  1. Day 9

    Every PLA plate printed

    Eighteen plates and about 39 hours of printing later, every PLA part of the duck exists, and face plate v1 is in with its screen and camera. Only the TPU soles and beak edges are left, and the servos are still on their way.

  2. Day 8

    Firmware for a face

    The servos aren't here, but the head doesn't need the rest of the robot to come alive. A bench stand, firmware for the eye, camera, microphone and speaker, a small servo driver, and a ten-page guide to wiring it all up.

  3. Day 8

    A screen for an eye, a camera for the other

    The screen and the XIAO camera board arrived, so out came the calipers. Face plate v1 holds both. Getting there took a drooping lip, a wedge-shaped tab and a camera 4 mm off.

What we changed

All our changes
  • The hood, a swappable face and its rings pulled apart

    A face that comes off

    A taller hood and a face held on by three magnets. A new face is a 49-minute print.

  • The round screen sitting in the back of the face plate

    A screen for an eye

    A 1.28" round screen and a XIAO camera board, so the duck can look, listen and talk.

  • A render of the whole duck standing

    A cleaner print file

    27 STLs composed into one Bambu Studio project: 20 plates, about 40 hours, and seven versions to get there.
