Luminae Signal Expression Protocol (LSEP)
Spec v2.1-rc1 (release candidate)

The Open Standard for Human‑Robot Communication

Some 4.66 million industrial robots already operate worldwide (IFR World Robotics), and analysts project roughly half a million humanoid robots shipping per year by 2032 (Goldman Sachs). None of them has a standard way to tell you what it’s about to do.

Spec v2.1-rc1

No standard exists.

Today, robots lack a universal communication protocol, creating massive silos.

Regulation without protocol.

Global regulations demand compliance, but don’t define how to communicate intentions.

Trust cannot be ad-hoc.

Ad-hoc signals fail at scale. Universal trust requires universal language.
