Resurrecting extinct cephalopods with biomimetic robots to explore hydrodynamic stability, maneuverability, and physical constraints on life habits [PDF]
Scientific Reports, 2022 Externally shelled cephalopods with coiled, planispiral conchs were ecologically successful for hundreds of millions of years. These animals displayed remarkable morphological disparity, reflecting comparable differences in physical properties that would

On turning maneuverability in self-propelled burst-and-coast swimming
The Physics of FluidsFish have evolved remarkable underwater turning maneuverability, primarily under active control. This allows them to execute turns within confined spaces, such as during C-start rapid turning.

Trailer-Maneuverability in N-Trailer Structures
IEEE Robotics and Automation Letters, 2020 The letter presents a trailer-maneuverability analysis for the N-trailer kinematic structures comprising a tractor and an arbitrary number of single-axle trailers equipped with steerable or fixed wheels. For an elliptically-shaped set of tractor's input-velocities, we derive a mobility-ellipse generated in a velocity space of the (last) trailer.

Snapp: An Agile Robotic Fish With 3-D Maneuverability for Open Water Swim [PDF]
IEEE Robotics and Automation Letters, 2023 Fish exhibit impressive locomotive performance and agility in complex underwater environments, using their undulating tails and pectoral fins for propulsion and maneuverability. Replicating these abilities in robotic fish is challenging; existing designs

Cooperative Guidance Law for High-Speed and High-Maneuverability Air Targets
Aerospace, 2023 In this paper, a novel cooperative and predictive guidance law is proposed to intercept high-speed and high-maneuverability targets with inferior interceptors. The purpose of guidance is cooperatively covering the most-probable locations where the target

Noisy pursuit and pattern formation of self-steering active particles
New Journal of Physics, 2022 We consider a moving target and an active pursing agent, modeled as an intelligent active Brownian particle capable of sensing the instantaneous target location and adjusting its direction of motion accordingly.

Maneuverability-Agility Plot (MAP).
, 2023 Experimental measurements of freely swimming B. vitrea (red dots) and for all simulated cases of modes 1, 2, and 3 (blue dots). Lower values of indicate sharp turns (more maneuverable); higher values of indicate faster swimming (more agile).
