Eel-like robot
A collaboration between the Unsteady Flow Dynamics Lab (UNFoLD) and Biorobotics Laboratory (BioRob) of EPFL. Anguilliform swimmers, like eels or lampreys, are highly efficient swimmers. Our research aims to understand their swimming using 1-guilla, an undulatory bio-inspired robot:
Gallery of fluid motion, award winning video
Our video of 1-guilla got an award at the 2023 Gallery of fluid motion! The video describes the findings of our Scientific Reports study through a colorful journey:
Water-channel testing
A second version of 1-guilla is designed to swim in our water channel to investigate further anguilliform swimming in the areas of collaborative swimming, sensing and control:
