Launching the AquaMAV: bioinspired design for aerial-aquatic robotic platforms
Robert Siddall,M. Kovac +1 more
TLDR
This evaluation proposes key design principles for the design of successful aerial-aquatic robots, i.e. using a plunge diving strategy for water entry, folding wings for diving efficiency, water jet propulsion for water takeoff and hydrophobic surfaces for water shedding and dry flight.Abstract:

Dynamic Modeling, Analysis, and Testing of a Variable Buoyancy System for Unmanned Multidomain Vehicles
Marc MacLeod,Matthew Bryant +1 more
TL;DR: In this article, an active variable buoyancy system (VBS) actuator for underwater vehicles is presented, which consists of an elastic bladder housed within a rigid ballast tank, hydraulic pump, and proportionally controlled vent valve.

A novel degree of freedom in flapping wings shows promise for a dual aerial/aquatic vehicle propulsor
TL;DR: In this paper, a preliminary realization of a flapping wing actuation system for use in both air and water is discussed, which employs an active in-line motion degree of freedom to generate the large force envelope necessary for propulsion in both fluid media.

Submersible unmanned flying boat: Design and experiment
TL;DR: The Flying Fish created by Beihang University will be introduced to verify the feasibility of this kind of novel aircraft which achieves its ability to transfer between the air and the water by imitating the flying fish and aquatic birds.

Bio-inspired soft aerial robots: adaptive morphology for high-performance flight
TL;DR: In this paper, the authors provide an overview of several examples in which softness is used in aerial robotics, outlining instances where inspiration from biology can be taken to develop next generation aerial robots which selectively use soft materials and adaptive morphologies to achieve high-performance flight behaviours.

RHex: A Simple and Highly Mobile Hexapod Robot:
TL;DR: The design and control of RHex is described, a power autonomous, untethered, compliant-legged hexapod robot that achieves fast and robust forward locomotion traveling at speeds up to one body length per second and traversing height variations well exceeding its body clearance.

From swimming to walking with a salamander robot driven by a spinal cord model.
TL;DR: A spinal cord model and its implementation in an amphibious salamander robot is presented that demonstrates how a primitive neural circuit for swimming can be extended by phylogenetically more recent limb oscillatory centers to explain the ability of salamanders to switch between swimming and walking.
Journal ArticleDOI
Functions for fish mucus
TL;DR: This work has shown that mucus-based defences, including filter feeding, adhesion and abhesion, can be modelled on the basis of the state of mucus on fish surfaces and experimental approaches.

Aerodynamics of Low Reynolds Number Flyers
TL;DR: In this paper, the authors introduce fixed, rigid, flexible, and flapping wing aerodynamic models for fixed and flexible wing aerodynamics, and propose a flexible wing model for flapping aerodynamics.
