3D preview

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

Mounting and application

SO-ARM100 interface is documented; derived from Reachy 2 geometry. No cobot or delta mount verified. [S001] [S002] [S003]

Before sourcing the build

Choose standalone, SO-ARM100 interface or camera-mount configuration, then follow the README’s external BOM link. The README names LeRobot for configuring the motor before assembly, and pypot’s support-feetech-sts3215 branch for flashing and testing. Match compatible library revisions before following these instructions. The approximately EUR 25 headline is not a complete current setup quote. [S001] [S002] [S003]

Files and reuse terms

The README and license state CC-BY-SA-4.0. Sharing the licensed material requires retaining supplied attribution and license notices and indicating modifications; sharing adaptations also carries ShareAlike conditions. The selected control dependencies and purchased components require their own source and license review. [S001] [S002] [S003]

The source inventory lists STEP and STL files. The external BOM and linked assembly/control resources were not established as a complete configuration-matched package in this review; this does not mean they are absent. Current delivered cost and measured performance are not established; no hardware was built or tested for this profile.

Cost

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

Source files and licenses

CC-BY-SA-4.0 in README and license. Match standalone versus SO-ARM100 configuration; retrieve linked external BOM and match the motor-control library. The approximately EUR 25 headline is not a complete current setup quote.
