Robot URI (RURI)

Every OpenCastor robot has a canonical RURI — a structured identifier modeled after URLs for physical machines.

Format

rcan://<registry>/<manufacturer>/<model>/<version>/<serial>

Example

rcan://opencastor.com/raspberrypi/pi5-hailo/1.0/RRN-000000000001

Component	Value	Description
registry	opencastor.com	Fleet registry domain
manufacturer	raspberrypi	Hardware manufacturer
model	pi5-hailo	Model + hardware tier
version	1.0	Hardware revision
serial	RRN-000000000001	Unique Robot Resource Name

RRN

The Robot Resource Name is the stable unique identifier assigned at registration. It's used in:

• All Firestore documents
• RCAN message headers
• Telemetry streams
• Castor Credits accounting
• Research contributor lineage

Format: RRN-{12-digit zero-padded integer}

RRN-000000000001   ← first registered robot
RRN-000000000005   ← fifth registered robot

Registration

castor register \
  --name "Bob" \
  --hardware pi5-hailo \
  --model "Raspberry Pi 5 + Hailo-8L"

The RRN is assigned by the registry and stored in the robot's config. It never changes.
