The role of optic flow pooling in insect flight control in cluttered environments

Dario Floreano, Julien Jean Denis Nicolas Lecoeur, Emily Baird

Flight through cluttered environments, such as forests, poses great challenges for animals and machines alike because even small changes in flight path may lead to collisions with nearby obstacles. When flying along narrow corridors, insects use the magnit ...

Learning Vision-based Flight in Drone Swarms by Imitation

Dario Floreano, Fabrizio Schiano, Julien Jean Denis Nicolas Lecoeur, Fabian Maximilian Schilling

Decentralized drone swarms deployed today either rely on sharing of positions among agents or detecting swarm members with the help of visual markers. This work proposes an entirely visual approach to coordinate markerless drone swarms based on imitation l ...

Insect-Inspired Visual Perception for Flight Control and Collision Avoidance

Julien Jean Denis Nicolas Lecoeur

Flying robots are increasingly used for tasks such as aerial mapping, fast exploration, video footage and monitoring of buildings. Autonomous flight at low altitude in cluttered and unknown environments is an active research topic because it poses challen ...

Spatial Encoding of Translational Optic Flow in Planar Scenes by Elementary Motion Detector Arrays

Dario Floreano, Julien Jean Denis Nicolas Lecoeur, Emily Baird

Elementary Motion Detectors (EMD) are well-established models of visual motion estimation in insects. The response of EMDs are tuned to specific temporal and spatial frequencies of the input stimuli, which matches the behavioural response of insects to wid ...

Miniature artificial compound eyes for optic-flow-based robotic navigation

Dario Floreano, Ramon Pericet Camara, Julien Jean Denis Nicolas Lecoeur, Gerard Bahi Vila

Miniature curved artificial compound eyes (CURVACE) represent a promising tool to assist in navigation of mobile robots. In particular, they feature ideal properties for minidrones to navigate safely in indoor environments due to its panoramic field of vie ...

A Flying Robot with Adaptive Morphology for Multi-Modal Locomotion

Dario Floreano, Ludovic Daler, Julien Jean Denis Nicolas Lecoeur, Patrizia Bernadette Hählen

Most existing robots are designed to exploit only one single locomotion mode, such as rolling, walking, flying, swimming, or jumping, which limits their flexibility and adaptability to different environments where specific and different locomotion capabili ...
