Living organisms routinely navigate their surroundings in search of better conditions, more
food, or to avoid predators. Typically, animals do so by integrating sensory cues from the …

Flagella and cilia are slender structures that serve important functionalities in the
microscopic world through their locomotion induced by fluid and structure interaction. With …

The unique motion styles of flagella and cilia (ie, planar/helical waveform propulsion of
flagella and two-dimensional (2D)/three-dimensional (3D) asymmetric ciliary beating), play a …

Navigating environments with low Reynolds numbers (Re), where viscous forces dominate,
presents unique challenges, such as the need for non-reciprocal motion dynamics …

We explore the idea of robotic mechanisms that can shift between soft and rigid states, with
the long-term goal of creating robots that marry the flexibility and robustness of soft robots …

Many eukaryotic microorganisms propelled by multiple flagella can swim very rapidly with
distinct gaits. Here, we model a three-dimensional mutiflagellate swimmer, resembling the …

Terrain irregularities in natural environments present mobility challenges for autonomous
robots and vehicles. Loosely consolidated sandy slopes flow unpredictably when perturbed …

Stability, adaptability, and maneuverability are critical performance indexes for underwater
biomimetic robots, especially in narrow spaces. However, these aspects can sometimes be …

Motility is an essential factor for an organism's survival and diversification. With the advent of
novel single-cell technologies, analytical frameworks, and theoretical methods, we can …

We study a slender filament beating in a viscous fluid with novel curvature-dependent
bending stiffness. Our numerical and experimental investigations reveal that such differential …
