Transcrição

The ability to measure deformations of soft robotic fins non-intrusively is important because we can better inform fin design and control for underwater vehicles and validate computational models. We can repurpose an existing tool within fluid dyn

The present protocol involves the measurement and characterization of 3D shape deformation in underwater flapping fins built with polydimethylsiloxane (PDMS) materials. Accurate reconstruction of these deformations is essential for understanding the propulsive performance of compliant flapping fins.
