"Arborescence 003" is a sculptural and interactive work composed of 1000 independent cellular robotic structures that are linked together. The bricks of the structure are like voxels with artificial intelligence in a real physical space.

The sculpture reacts like a living organism.

Each electronic cell perceives sounds and reacts according to the intonations of the voices and the duration of the vocalizations. Each of the 1000 electronic cells is retroactive. The artwork surface is made of 1000 micro-controllers, 1000 independent micro-speakers, 1000 light sources, 1000 x 6 - 6000 serialconnectors .. Etc..

They emit different sound behavioural scenarios, rhythms and bright colors in response to stimuli from audiences and neighbouring cells.
A sound stimulus influences the robotic bases between them, between neighbouring cells, like cooperative living organisms.

The communications become visible with the chase effect light and sonorous shifting inside the structure.




This artwork was realised during a period of residency at Numerica / MA scène nationale - Pays de Montbéliard

Support and co-production : MA scène nationale - Pays de Montbéliard

Artwork realised with the support of the VERTIGO project as part of the STARTS program of the European Commission, based on technological elements “Programmable Matter” from the research lab FEMTO-ST / CNRS

Award : Guiness world record 2022 : Largest autonomous light block robotics structure



























In august 2021 we have realised a very large version of the artwork for candidate to the Guinness World Records
with 1824 “Blinky blocks” : autonomous cellular robotic structures at Numerica / MA scène nationale - Pays de Montbéliard
with the help of the team from the research lab FEMTO-ST / CNRS : Julien Bourgeois, Benoit Piranda, Frédéric Lassabe and Rémy Tribhout
