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:

Statics Analysis and Design of the 6-DOF Lower Limb Bionic Leg
TL;DR: In this paper, a lower limb bionic leg is presented based on 3-UPS parallel mechanism, which has the characteristics of movement flexible and strong adaptability, in order to improve ability of walking and crossing the barriers, increase the carrying capacity, and enhance its popularity and adaptability.

Nonlinear modeling and experimental verification of Gannet-inspired beam systems during diving.
TL;DR: A nonlinear model is proposed to answer at which diving speeds and beak angles will cause injury to Gannet-inspired beam systems during plunge-diving, and shows that the system with the smallest half-beak angle and thus the lowest drag force and beam length delays the critical velocity and is most representative of a Gannets during diving.

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.

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.
