THE EXPERIENCE DESIGN INSTITUTE

Building the Infrastructure for Human-Robot Trust.

The governing body behind LSEP — the open standard for how robots communicate intent to humans. We certify physical AI systems for safety, compliance, and human legibility.

The Experience Design Institute (EDI) is the official governing body of LSEP (Luminae Signal Expression Protocol), the first open-source, physics-based communication standard designed to ensure humanoid robots comply with EU AI Act (Annex IV) and ISO 13482 safety regulations for human-robot interaction (HRI).

What We Believe

Our Belief: Silence between humans and autonomous machines is dangerous. Opaque robot behavior breeds fear and resistance. When a 200kg machine approaches you and you have no idea what it's about to do — that's not innovation. That's negligence.

Our Mission: We believe every human has the fundamental right to know what a physical AI system is about to do. Not through screens. Not through apps. Through the machine itself — directly, physically, unmistakably. This is the foundation of human-robot interaction.

Our Solution: We don't build robots. We build the open standard for trust between humans and machines. Physics-based, universally understood, and designed for interoperability across every platform. No discrimination, no surveillance. Just light, sound, and motion.

Our Standard: LSEP is not a product. It's infrastructure. Like Bluetooth gave us wireless audio, like USB-C gave us universal power — LSEP gives robots a voice. An honest one. Built for robot safety, designed for transparency.

THE PROTOCOL

1 Protocol. 9 States. 3 Modalities.

LSEP (Luminae Signal Expression Protocol) is the first formal Human-Robot Interaction (HRI) standard for intent signaling and algorithmic transparency. A robot communication protocol independent of facial recognition. The robot's perception stays private; its intent becomes visible. Every signal is physics-based. Every state is human-legible. Every implementation is auditable — ensuring full robot safety compliance and interoperability across platforms.

Light

LED arrays and light patterns communicate intent. Color-coded states: red for caution, green for safe approach, yellow for uncertain motion. Visible from all angles, impossible to miss.

Sound

Auditory signals provide redundancy. Frequency-based notifications allow hearing-impaired users to understand robot state. Sub-audible warnings for precision navigation.

Motion

Kinematic expressions — predictable movement patterns that signal intent. Deceleration, orientation, and temporal pacing all convey meaning. Physics-based and learnable.

FREQUENTLY ASKED QUESTIONS

Technical FAQ

What is LSEP?
LSEP (Luminae Signal Expression Protocol) is an open-source communication standard that enables robots and autonomous machines to communicate their internal states and intentions to humans through physics-based signals — light patterns, sound frequencies, and kinematic expressions. It is administered by the Experience Design Institute (EDI).
How does LSEP comply with the EU AI Act?
LSEP provides protocol-level state logging and human-legible intent signaling, addressing key EU AI Act requirements for high-risk AI systems (Annex IV). Every robot state is documented, traceable, and auditable, supporting transparency obligations under Article 13.
Is LSEP compatible with ROS 2?
Yes. LSEP is designed as a middleware-agnostic communication layer. Reference implementations are available for ROS 2 (Robot Operating System), and the protocol can be integrated with any robotics framework that supports structured state messaging.
What robot types does LSEP support?
LSEP supports humanoid robots, collaborative robots (cobots), autonomous mobile robots (AMRs), industrial manipulators, and service robots. The protocol is platform-independent and scales from single-robot deployments to multi-robot fleet operations.
How does LSEP ensure interoperability?
LSEP defines a universal state machine with 9 standardized states and 3 signal modalities. Any LSEP-certified robot uses the same signal vocabulary, ensuring consistent human-robot interaction across manufacturers and platforms — similar to how Wi-Fi ensures wireless interoperability.
Where can I find the LSEP specification?
The full LSEP specification is available on lsep.org and the GitHub repository at github.com/NemanjaGalic/LSEP. The specification is open-source and free to implement.
