Pogobot

Sorbonne Université ISIR / ESPCI Paris-PSL (France) · 2022

Not for saleNever sold. The 2025 arXiv paper puts the assembled cost at about €250 per robot (about $290 converted), and no company, shop or ordering page was found (October 2026 check of the project site and GitHub). Labs build their own from the open design, with the main circuit board made by an electronics assembly service and the rest 3D printed. Year 2022 is when the hardware and SDK repositories went public on GitHub; the main paper followed in April 2025.

Not for saleShipping: Not for sale. Not sold. All design files, 3D-printable parts and software are open on GitHub, so labs build their own; only the main Head board needs a professional electronics assembly service. Pogobot project site ↗
Remote control: Programs are compiled on a computer and loaded over a USB serial cable one robot at a time, or sent to many robots at once with the handheld PogoShower or an infrared Pogowall. The SDK officially supports only Ubuntu Linux (or a Singularity container), so a Mac needs a Linux virtual machine; the Pogosim simulator has macOS install instructions.

Overview

An open-source swarm robot from Sorbonne Université and ESPCI Paris-PSL, designed as a modern replacement for the discontinued Kilobot and used for both swarm robotics and active-matter physics. Robots talk to each other over four directional infrared channels, sending 64-byte messages at 60 Hz with nearly perfect delivery up to 10 cm, and each receiver tells the robot which of eight directions a message came from. In crowded groups a simple random-send rule (the Banshee protocol) spreads messages from robot to robot like gossip, and a handshake mode is available when two robots must be sure an exchange happened. More than 200 units were in daily use at several universities by 2025, including Université de Lorraine and Ochanomizu University in Japan. The catch is that it cannot be bought, so a lab has to order the boards, 3D print the shells and assemble each robot itself.

Specifications

CategoryWheeled rovers · Research mobile manipulators & platforms
Released2022
CountryFrance
AvailabilityNot for sale (research)
ProgrammabilityOpen source (hardware + software)
Built-in autonomyNone / scripted · Moves only when controlled, or plays preset motions
LLM supportNone · No LLM features. Programs are small C files compiled for a RISC-V soft processor and loaded by cable or broadcast over infrared.
MuJoCo simulationNone found · Nothing found.
NVIDIA Isaac simulationNone found · Nothing found.
Gazebo simulationNone found · Nothing found. The team's own Pogosim simulator (C/C++, Box2D) runs the same C code as the real robots, models infrared packet loss and simulates 100 robots 14 to 21 times faster than real time. It is modeled on the Kilombo simulator used for Kilobots.
