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!!

Our Swarm of DotBots

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.

Scalability issues with Bluetooth? Fixed โœ…
Weโ€™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 โ€” IETF 123 in Madrid

Back from IETF-123 in Madrid ๐Ÿ‡ช๐Ÿ‡ธ where I merged two projects I deeply care about:

  • ELA: secure zero-touch enrollment for IoT
  • Mari: our โ€œmini 5Gโ€ network for robot swarms
    We integrated ELA security into Mari at the hackathon and demoed it live! ๐Ÿš€

20 Jun 2025 โ€” Teaser of Mari testbed

Mari allows controlling 40 โ€œfake robotsโ€ in real time using a BLE radio.

12 Jun 2025 โ€” Paper at DCOSS-IoT

We presented our latest paper at DCOSS-IoT 2025:
ELA (Lightweight Authorization over EDHOC) โ€” a protocol that makes IoT enrollment:

  • secure ๐Ÿ”’
  • lightweight โšก
  • automated ๐Ÿค–
  • standard ๐Ÿ“œ

08 Jun 2025 โ€” Automatica 2025

Thrilled to join Automatica 2025 ๐Ÿค– in Munich with OpenSwarm partners!
We showcased swarm robotics demos: aquatic robots, aerial drones, and micro-robots.

15 May 2025 โ€” OpenSwarm Hackathon at Inria

At our OpenSwarm hackathon, we stress-tested the swarm infrastructure.
The approach: test early, break soon, fix fast ๐Ÿ”ง.
Result: ~10ร— improvements in reliability, and plenty of insights to fuel the next iteration.


02 Apr 2025 โ€” Visit to HKUST (Guangzhou)

Had a great visit to HKUST Guangzhou ๐Ÿ‡จ๐Ÿ‡ณ 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.

24 Apr 2024 โ€” Paper at WCNC

Presented our paper on EDHOC vs DTLS 1.3 at IEEE WCNC.
Results:

  • ร—6โ€“14 smaller packets
  • ร—1.4 faster handshakes
  • ร—2.8 less energy

EDHOC proves a strong fit for constrained IoT – read the paper here.


10 Nov 2023 โ€” IETF 118 in Prague

My first time at an IETF event ๐Ÿ™Œ
An amazing atmosphere of hacking, standards, and collaboration.
I joined the LAKE WG to work on EDHOC and ELA, helping shape the future of IoT security.


01 Apr 2023 โ€” ๐Ÿ‡ง๐Ÿ‡ท -> ๐Ÿ‡ซ๐Ÿ‡ท Joining Inria

Started as Research Engineer at Inria ๐Ÿ‡ซ๐Ÿ‡ท!
Working on IoT security standards such as EDHOC and zero-conf onboarding methods.


12 Mar 2023 โ€” Talk in Virmond

Honored to return to my hometown Virmond (4k people, rural Brazil ๐Ÿ‡ง๐Ÿ‡ท) and talk to students about tech opportunities.
With remote work and the Internet, the world is closer than ever. ๐ŸŒ


24 Jan 2023 – Smart Cities IoT Pilot in 20 Police Cars!

We installed “Sentinel” devices in two more police cars in Sรฃo Paulo. They use AI to identify license plates and guns, helping the police to keep Sรฃo Paulo a safer place to all its citizens. The project is part of a Smart Cities pilot in the city of Sรฃo Paulo.

25 Oct 2022 โ€” PhD defense!

Successfully defended my PhD ๐ŸŽ“ at USP (Sรฃo Paulo).
Dissertation: Protecting interactions in IoT swarms.
Grateful to advisors, parents, and colleagues who made it possible.

23 Jun 2022 โ€” Paper at GIoTS

Presented A Low-Overhead Approach for Self-Sovereign Identity in IoT at GIoTS Dublin ๐Ÿ‡ฎ๐Ÿ‡ช.
We showed how to enable decentralized IoT identity even on constrained networks.


25 Ago 2022 – Pulga mini testbed

We built a small testbed for the Pulga board, a modular nRF52840-based IoT node. In the setup, we use 6 pulgas, each connected to a GPS and a LoRa module. We conduct experiments to evaluate packet delivery ratio and distance.
