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

Configuration and sourcing

The original RUKA BOM and current website print files have not yet been matched to one build configuration.

December 19, 2024 BOM lists 11 XL330-M288-T motors, U2D2, tendons, PTFE tube, springs, pins, power wiring and 5 V 30 A supply; tools separately listed. The upstream December 19, 2024 single-hand BOM totals are $519.94 without tools and $762.76 with tools, including its printer allowance. These are dated BOM figures, not current supplier quotations. Host compute and teleoperation input equipment are not listed in that BOM. [S001] [S002] [S003] [S004] [S005] [S006]

Print/postprocess parts, install inserts, assemble finger/wrist mechanisms and tendons, wire supply, assign motor IDs and match controller checkpoints. The README describes a Conda environment, USB-port configuration and OSF credentials for its download script. The learned-controller route requires OSF checkpoints and build-specific tendon calibration; this review has not established that the external checkpoints match the selected hardware. [S001] [S002] [S003] [S004] [S005] [S006]

Integration

Documentation reports direct Franka and xArm mounting and a separate Kinova adapter; no particular arm generation tested here. [S001] [S002] [S003] [S004] [S005] [S006]

Design limits and source rights

Downloaded print-page labels use XM430 while dated BOM specifies XL330. Linked STL requests returned HTTP 403. Resolve the BOM/print-file mismatch and retrieve the selected geometry before buying a matched set.

Live teleoperation has two documented routes: MANUS gloves with a streaming SDK and the Bidex_Manus_Teleop submodule, or Oculus with the externally installed OpenTeach application. Pin the MANUS submodule; recording the OpenTeach revision is an editorial reproducibility recommendation. The README also provides saved keypoints for initial controller use, which is distinct from sourcing live teleoperation input equipment. [S001] [S002] [S003] [S004] [S005] [S006]

The repository MIT text covers software and associated documentation and requires preservation of the copyright and permission notice. Rights for the external fabrication files and OSF weights/data remain unestablished. [S001] [S002] [S003] [S004] [S005] [S006]

This is a source-researched design profile. We have not assembled or tested this configuration; no complete current setup price is established.

Cost

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

Source files and licenses

Source-researched component coverage; complete build, commercial rights and performance qualification remain separate.
