A resonant squid-inspired robot unlocks biological propulsive efficiency
Thierry Bujard, Francesco Giorgio-Serchi, Gabriel D. Weymouth
Abstract
The robot also exhibits a preferred Strouhal number for efficient swimming, thereby bridging the gap between pulse-jet propulsion and established findings in efficient fish swimming. Extensions of the current robotic framework to larger amplitude oscillations could combine resonance effects with optimal vortex formation to further increase propulsive performance and potentially outperform biological swimmers altogether.
