A minimal robophysical model of quadriflagellate self-propulsion [PDF]
Bioinspiration & Biomimetics, 2021 Abstract Locomotion at the microscale is remarkably sophisticated. Microorganisms have evolved diverse strategies to move within highly viscous environments, using deformable, propulsion-generating appendages such as cilia and flagella to drive helical or undulatory motion. In single-celled algae, these appendages can
