Advanced Maker Project

Microduck Biped

Difficulty: Advanced Maker
Build Time: ~5-6 Hours
Est. Cost: ~$180 BOM
14 Bus Servos

An open-source bipedal robot selected as SeedCore’s primary reference embodiment. Compact 0.737 kg body, 14 degrees of freedom, and 38 3D-printable parts.

Consumer Quickstart: 3D-print parts in PETG/PLA, assemble leg linkages with M2/M3 screws, and connect to SeedCore's native MuJoCo workbench to verify zero-drift initial stance before powering hardware.

Best Beginner / Family Build

SO-100 / Tabletop Arm

Difficulty: Beginner Maker
Build Time: ~90 Minutes
Est. Cost: ~$150 BOM
Tools: 2mm Hex Key

The popular 3D-printed leader-follower robotic arm driven by low-cost Feetech STS3215 magnetic encoder serial bus servos. Ideal for desktop teleoperation and ACT training.

Consumer Quickstart: 3D-print 6 arm brackets, screw in 5 bus servos with the included hex key, daisy-chain the 3-pin snap cables, and plug into your laptop with USB-C. No soldering or Linux required.

Companion Reference

Desktop AI Companion

Reachy Mini

Difficulty: Intermediate
Build Time: ~2-3 Hours
Focus: Voice Companion
Kid Safe: 100%

An expressive desktop companion robot with its own upstream SDK. SeedCore retains earlier Reachy integration work as a multi-joint companion reference alongside Microduck.

Consumer Quickstart: Mount the 3-DOF pan-tilt neck mechanism and webcam. Connect to your voice assistant of choice to synchronize real-time nods, head-tilts, and expressive eye animations with audio responses.
