URML (open robot intent language): a validated-intent layer above BotBrain (request for comment) #11

Description

@idoco2003

Hi BotBrain community,

URML (urml.dev) is a small, Apache-2.0 language for describing robot intent: an intent becomes a typed primitive, validated against the robot's declared capabilities and a safety envelope, then dispatched. BotBrain is a modular brain for legged robots (teleop, nav, mapping on ROS 2), and URML is interesting as the validated-intent layer that sits above it and routes into its existing modules.

Nothing here asks the project to adopt, host, or maintain anything. This is a request for comment.

The mapping: the legged platform BotBrain drives declares its mobility (a legged drive type), its whole_body stability limits, and its named locations as a URML manifest. A high-level or natural-language command becomes a typed URML primitive, validated against that manifest, then routed to BotBrain's navigation or teleop path. URML is the typed gate and intent record; BotBrain stays the runtime that moves the legs.

Two real questions: (1) does a URML manifest for the legged platform (legged drive type + whole_body limits + locations) fit how BotBrain models its robot? (2) Is a validated-intent layer above the nav / teleop modules interesting, or already covered by something in the stack -- and which is the cleaner first seam?

Thanks for BotBrain; a modular legged-robot brain is a natural place to ask where a validated-intent gate fits.
