Assembly and use
Configuration and sourcing
The reviewed commit is 7bb2f23485a7d440960c21046da642de132b7745, accessed September 30, 2026. Select left or right hardware before reconciling the seven-actuator tendon system. Begin with the pinned hardware/Assembly/BOM.csv and hardware/CAD files; the README links the upstream assembly guide, whose complete contents were not reviewed here. [S001] [S003] [S005]
7 Feetech HLS3606M servos, springs, tendons, pins/bearings, ESP32-S3, TTL linker, printed structures and soft pads. BOM contains optional parts and blank cost rows. Its notes assume PLA printing with a 0.4 mm nozzle and give fit guidance for undersized pins and bearings. The BOM recommends silicone pads for compliance and grip and reports reduced functionality with TPU; this is upstream guidance, not our measurement. Reconcile that choice and choose the intended electronics route: servo junction boards, optional protoboard parts or PCB. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008]

Integration
Repository lists Piper, tripod and Unitree G1 adapters; source availability does not establish every host/control combination. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008]
Design limits and source rights
README USD 314 kit headline and BOM numeric total 316.482991 are not established as directly comparable; BOM currency/pack assumptions need reconciliation. Obtain an itemized kit contents list before attributing the discrepancy to scope; quote either an exact kit or a reconciled self-source configuration.

Hardware/docs CC BY-NC-SA 4.0; firmware and SDK Apache-2.0. Licensing guide separately describes commercial integration of purchased units; that does not authorize commercial manufacture from design files, which the guide says requires a separate commercial manufacturing license. Noncommercial redistribution and modified files require attribution and sharing under the same license as described by the guide. [S001] [S002] [S003] [S004] [S005] [S006] [S007] [S008]
Upstream describes a research prototype without prolonged or heavy-duty validation. [S001]
