Underwater Navigation in Unsteady Flows Using Measurement Histories from a Single Sensing Unit
Linhao Jin, Qimin Feng, Peter Gunnarson +1
Spatial flow measurements support underwater navigation, but distributed sensing is constrained by robot size and sensor layout. We use a causal observer to estimate current latera…
A reconfigurable multi-axis cyber-physical framework for multi-regime fluid--structure interaction experiments
Zihan Zhang, Alex Sorensen, Qimin Feng +3
Fluid--structure interaction (FSI) experiments are typically built around mechanical dynamics and constraints imposed by the physical apparatus, so changing mass, stiffness, dampin…
Inertial effects on the mechanical efficiency of a semi-passive oscillating hydrofoil energy harvester
Zihan Zhang, Qimin Feng, Yuanhang Zhu +1
Oscillating-foil-based energy harvesters have demonstrated strong potential for low-speed hydrokinetic energy extraction; however, the actuator-level mechanical energy balance asso…
Passive Phase-Oriented Impedance Shaping for Rapid Acceleration in Soft Robotic Swimmers
Qimin Feng, Orion A. Roberts, Qiang Zhong
Rapid acceleration and burst maneuvers in underwater robots depend less on maintaining precise resonance and more on force--velocity phase alignment during thrust generation. In th…
Wavenumber affects the lift of ray-inspired fins near a substrate
Yuanhang Zhu, Leo Liu, Tianjun Han +4
Rays and skates tend to have different fin kinematics depending on their proximity to a ground plane such as the seafloor. Near the ground, rays tend to be more undulatory (high wa…
