Yeah Hand

Based on published sources · Not tested by us ·

Overview

Yeah Hand/Rebelia lineage: humanlike hand with separate robot/prosthetic firmware and commercial servos. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008] [S009] [S010] [S011]

Yeah Hand provides robotic and prosthetic hand configurations with different controls. This entry also retains the related Rebelia V1 lineage as version context, rather than treating it as a separate independent design. Select the configuration before matching firmware, electronics and released geometry. [S003] [S005] [S009]

Preview not available yet. A model has not yet been prepared and approved for display on this page. This does not mean the project lacks CAD files; see Source files and licenses for the reviewed source availability.

Assembly and use

Robotic versus prosthetic build

The V2 BOM lists five WaveShare ST3215 servos. The robotic version uses a purchased WaveShare ESP32 Servo Driver; the prosthetic version uses a custom PCB and EMG sensors. Start with hardware/BOM.md and hardware/Electronics/Readme.md to distinguish these routes. Neither electronics route establishes a cobot or delta mounting flange. [S004] [S015]

Fabrication uses different materials for different parts, including flexible fingers in TPU with PLA/ABS, a PLA/PETG thumb base and PLA covers. Tendon material and the selected geometry must match. The BOM still leaves wrist-fastener details unfinished, so it does not yet provide a fully reconciled shopping list. [S004]

CAD is distributed through release assets. Match the chosen release to the current documentation and firmware before fabrication; the reviewed documents do not establish that every release and branch combination is compatible. [S005]

Rights and control dependencies

The project declares CERN-OHL-S-2.0 for hardware, GPL terms for firmware and Creative Commons terms for documentation. Read the particular file notices rather than applying one license to the entire build. [S002] [S012] [S014]

The firmware instructions list external libraries, including modified ESP32FFT material described as having a custom license. Pin those dependencies and obtain their license texts before relying on reuse rights. The project’s GPL declaration does not settle every dependency or the source rights of the purchased controller. No complete delivered cost, hardware build or performance test is established here. [S013] [S015]

Cost

No current, complete configuration-specific build cost has been established for this profile.

Source files and licenses

CERN-OHL-S-2.0 hardware; GPL firmware; CC-BY-SA documentation. CAD is in release assets, not the default-branch tree. Match v1.2 asset and current docs before building; native Blender file is over 400 MB and not preserved here. Rebelia V1 is a related version, not an additional independent family.
