Coverage measures whether a selected public field is present with non-U evidence. It is not a product score, compatibility result, certification, availability confirmation or procurement recommendation. Download the complete readiness coverage JSON →
Exact-model responsibility-party BOM crosswalk.
This edge requires a pinned robot BOM identity and an exact RCI component record. It remains separate from as-built inspection, compatibility and performance evidence.
Robot BOM → exact component
OpenAMR multipurpose mobile platform
The pinned OpenAMR table identifies two AS5040 magnetic encoders. The RCI record represents the exact encoder IC while keeping magnet, PCB and mechanical stack outside that identity.
Published quantity: 2. Two source-table units are published; no serials, PCB assemblies, magnet identities or calibration records were inspected.
Boundary: The crosswalk does not establish mounted accuracy, wheel-odometry performance, current supply, endorsement or an RCI physical test.
1 bounded physical-evidence record.
Publisher independence, identity precision and measurement scope vary by row. Results remain bounded by the disclosed specimen, setup, workload and metric; an inconclusive mapping is evidence associated with the catalog model, not verification of a manufacturer claim.

Known limits
What this record does not prove.
- The IC record does not identify a breakout board, magnet, PCB, shaft or mechanical alignment.
- The public BOM quantity does not prove installation or calibration in a serialised robot.
- No RCI wheel-odometry or encoder-linearity test exists.
