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 ...
EPFL2019The 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 ...
2019Learning 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 ...
2019Spatial 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 ...
2018Miniature 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 ...
IEEE2014A 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 ...
2013A Bee in the Mirror: A Bio-Inspired Model for Vision Based Mid-Air Collision Avoidance
Julien Jean Denis Nicolas Lecoeur
The objective of much robotics research in recent years has been to develop lightweight autonomous flying robots. Applications for these aircrafts are numerous, including natural disaster monitoring, mapping, and search-and-rescue missions. One of the majo ...
