Erwin Lejeune Head of Robotics, SIRB.AI · Abu Dhabi

Eight years in robotics, one piece at a time.

I lead robotics software teams across orchestration, navigation and fault management, and I stay hands-on in ROS 2, C++, Python and Go.

Scroll and the arm picks up one chapter at a time. Move your cursor and it follows you. Drag to look around.

01 2014–2018 Nantes Université · Nantes

Electronics, first

A B.Sc. in Electronics Engineering at Nantes Université. The robots came later; the circuits came first.

  • B.Sc. Electronics Engineering

02 2018–2019 Hiventive · Bordeaux

A microcontroller, in software

As an embedded software engineer, I built a SystemC/TLM virtual prototype of an STM32: TIM, I2C, CAN, GPIO and USART, wired into QEMU. Same years: an M.Sc. in Computer Engineering & Aeronautics at Ynov Bordeaux.

Treat time, memory and bandwidth as a budget. Test against a model of the hardware first.

Two mazes, two wins

As a robotics assistant, I built full autonomy stacks from scratch with ROS and embedded systems, and won both maze-solving competitions: the mapped one and the unmapped one.

  • 2 of 2 competitions won
  • ROS from scratch

04 2019–2021 Centrale Nantes · Nantes

Four projects, two papers

An M.Sc. in Control & Robotics, then research: I led four projects on multi-agent pathfinding, PDDL planning, real-time ROS control on Xenomai, and ROS 2 latency. Same period, remote for Hiventive: Go services with PostgreSQL and Docker.

A robot in a real supermarket

Founding robotics engineer on the team that delivered the first working in-store robot. I led navigation: planning, motion control, localization. When the CTO left, I also took on trolley detection, trained interns and a junior engineer, and ran the sprints.

A real store changes your priorities fast.

From one robot to a swarm

I designed swarm behaviours, including bird-inspired flocking published at IROS 2024, then grew and led a team of 9. We cut onboard CPU by 74% and bandwidth by 52%, and worked with Caltech on their M4 robot. Demos led to USD 3M, then over USD 10M, in contracts.

Agents that stay in-house

I founded Unchained Labs: local-first AI agents that run on a company's own models, data and infrastructure. Kymatics, our graph-based orchestrator, turns a spoken intent into a queue of build jobs.

A swarm that heals itself

Head of Robotics, founding team. I designed the robotics architecture and a self-healing autonomy layer: fault and state recording across the swarm, agents that detect and recover from failures, ML-based mission scoring before launch. We went from prototype to public launch at UMEX 2026.

سرب sirb is Arabic for a flock, or a swarm.

On the bench

Things I build on my own time. Pick one and the monitor plays the real clip.

grip

A git hook that quizzes you on your own diff before you commit or push, grades the answers against a hidden rubric, and blocks anything below the pass mark.

Notes

Papers, upstream code, and writing

AI is a tool. The harness is the work.

AI lets a team ship more without lowering the bar, as long as every change goes through the same cell, whoever or whatever wrote it.

Basketball, films, photography

And Clanker Labs, my self-hosted home with an agent running it. The photos are mine; 2023 took me through California and the US West, Paris, Togo, Tokyo, the Maldives and Dubai.
