03-04 Dec 2025 - Teaching DotBots in La Réunion
We took our DotBots to the paradise island of La Réunion, where we taught the first edition of the “DotBot Academy” to 33 Computer Science students of L’École supérieure d’ingénieurs Réunion océan Indien (ESIROI).
26-27 Nov 2025 - Swarm Workshop and announcing LeSwarm
In late November 2025, five Horizon Europe projects about Swarms presented their results in the Swarm Workshop in Brussels, Belgium. During the event, I had the pleasure of giving a talk and a demo about the DotBot testbed. It was a very important moment not only meet our project partners once again, but also get to know the general european swarm landscape.
This was also the first time we discussed LeSwarm publicly – the company that is going to make the DotBots commercially available.
03-28 Oct 2025 - OpenSwarm Roadshow in Brazil
During October, I had the wonderful pleasure of visiting several universities in Brazil to present the DotBot Testbed and the developments of the OpenSwarm project. Specifically:
- University of São Paulo (USP)
- Salvador Arena Foundation
- Federal Technological University, Paraná (UTFPR)
01 Oct 2025 - Talk at JNRR 2025 in Rennes, France
Togetehr with Alexandre Abadie, we presented the DotBot and OpenSwarm Testbed tools to the French robotics community at the JNRR 2025 (the French National Robotics Research Days) in Rennes on September 30, 2025. This outreach activity marks a new step in consortium development, spreading awareness about the next generation of tools we’re creating under the OpenSwarm umbrella to advance swarm robotics research and education.
25 Sep 2025 - Deployment of 100 DotBots in Ireland
During an OpenSwarm all-hands meeting in Limerick, Ireland, we deployed the first batch of 100 DotBots, marking a significant milestone towards the deployment of the DotBot testbed, which aims to connect 1,000 robots.
22 Sep 2025 - 🏆 Best Demo Award at EWSN 2025!
We received the Best Demo Award at the International Conference on Embedded Wireless Systems and Networks (EWSN) 2025 in Leuven, Belgium! Our demo showcased Mari (Micro-robot Access Radio Infrastructure), featuring 120 devices connected through 2 gateways: 20 DotBots controlled in real-time from a web browser with over-the-air flashing capabilities, plus 100 additional wireless nodes proving the protocol’s scalability. The system achieved average latency under 250 ms and packet delivery ratio above 95%. This was also the debut of DotBot-v3, our newest robot platform for swarm robotics research and education.
19 Sep 2025 - 100 DotBots assembled!
We received all the parts needed to assemble our DotBot Swarm of 100 robots. The whole team got together to help in a true assembly line fashion, from screwing motors to flashing bootloaders. Exciting!!
16 Sep 2025 - SwarmIT stable with dozens of robots
SwarmIT, our tool for managing experiments in robotic swarms is now more stable and is able to flash 48 nodes in less than 30 seconds. Similarly, it takes only 5 seconds to start or stop an experiment. In the figure, we see 5 DotBots during an experiment.
23 Aug 2025 — Mari is a new link layer for connecting robot swarms!
Scalability issues with Bluetooth? Fixed ✅
We’re developing Mari, a new link layer and infrastructure that connects 100+ nodes per gateway (and thousands with more gateways). It enables responsiveness, OTA throughput, and fast roaming for robotic swarms.

29 Jul 2025 — IETF 123 in Madrid
Back from IETF-123 in Madrid 🇪🇸 where I merged two projects I deeply care about:
- ELA: secure zero-touch enrollment for IoT
- Mari: our “mini 5G” network for robot swarms
We integrated ELA security into Mari at the hackathon and demoed it live! 🚀
20 Jun 2025 — Teaser of Mari testbed
Mari allows controlling 40 “fake robots” in real time using a BLE radio.

12 Jun 2025 — Paper at DCOSS-IoT
We presented our latest paper at DCOSS-IoT 2025:
ELA (Lightweight Authorization over EDHOC) — a protocol that makes IoT enrollment:
- secure 🔒
- lightweight ⚡
- automated 🤖
- standard 📜
📄 Paper: https://hal.science/hal-05056807v1/file/ela-dcoss-short-camera-ready-05may2025.pdf
📄 IETF Draft: https://datatracker.ietf.org/doc/draft-ietf-lake-authz/
08 Jun 2025 — Automatica 2025
Thrilled to join Automatica 2025 🤖 in Munich with OpenSwarm partners!
We showcased swarm robotics demos: aquatic robots, aerial drones, and micro-robots.

15 May 2025 — OpenSwarm Hackathon at Inria
At our OpenSwarm hackathon, we stress-tested the swarm infrastructure.
The approach: test early, break soon, fix fast 🔧.
Result: ~10× improvements in reliability, and plenty of insights to fuel the next iteration.
02 Apr 2025 — Visit to HKUST (Guangzhou)
Had a great visit to HKUST Guangzhou 🇨🇳 to present Mari, our solution for connecting large-scale robot swarms.
Big thanks to Tengfei Chang and his team for the warm hospitality and inspiring discussions.
20 Mar 2025 — IETF 122 in Bangkok
At IETF 122 in Bangkok 🇹🇭 with Elsa López Pérez and Yuxuan SONG.
We pushed progress in three projects — including Mari and ELA — during hackathon sessions and WG meetings.
