OpenCastor Documentation

OpenCastor is a productized open-core RCAN runtime — Layer 4 of the OpenCastor stack. It bundles the robot-md-gateway safety kernel (Layer 3) with drivers, reactive safety, telemetry, fleet management, and a cloud bridge. The safety kernel is open and identical in every tier; OpenCastor's commercial value is in operational ergonomics, fleet scale, and compliance prep.

Where OpenCastor sits in the stack

Layer Project Role
1 robot-md Declaration — ROBOT.md manifest
2 (any MCP host) Agent runtime — Claude Code, Codex, Gemini
3 robot-md-gateway Mandatory exclusive enforcement path
4 OpenCastor ← this Productized robot-facing runtime
5 rcan-spec Wire protocol
6 RRF Identity + evidence registry
