A robotic identification number, or RIN, is a permanent identity for a physical robot. It stays with the robot through ownership changes, service, relocation, and retirement.
Every URF RIN is exactly 17 characters. The structure carries useful identity information while the sequence and check character protect the record from common errors.
| Position | Meaning | Purpose |
|---|---|---|
| 1–3 | Manufacturer | Three-character manufacturer code |
| 4–5 | Model | Two-character model code |
| 6 | Class | Autonomy or control class |
| 7 | Type | Primary robot type |
| 8 | Body | Physical form or body category |
| 9 | Mobility | Wheeled, legged, tracked, flying, or other mobility method |
| 10 | Energy | Primary power source |
| 11–12 | Year | Year manufactured, or 00 when unknown |
| 13–16 | Sequence | Unique allocation within the identity prefix |
| 17 | Check character | Helps detect typing or transcription errors |
The RIN should not change because the robot is sold, transferred, repaired, relocated, or retired. Those events belong in the robot record and future Robofax history.
