This study describes the amphibious study of a novel robot, which attempts to emulate the basilisk lizard’s ability to run on the surface of water and walk on land. Functionally, the robot uses four bar mechanism as its driving leg with a self-adaptive foot added to its end. Through some hydromechanics calculations and analyses, its water running ability is theoretically verified. And via terre...

This article presents AmphiBot II, an amphibious snake robot designed for both serpentine locomotion (crawling) and swimming. It is controlled by an on-board central pattern generator (CPG) inspired by those found in vertebrates. The CPG is modelled as a chain of coupled nonlinear oscillators, and is designed to produce travelling waves. Its parameters can be modified on the fly. We present the...

The transition from aquatic to terrestrial habitats was a seminal event in vertebrate evolution because it precipitated a sudden radiation of species as new land animals diversified in response to novel physical and biological conditions. However, the first stages of this environmental transition presented numerous challenges to ancestrally aquatic organisms, and necessitated changes in the mor...

The deep sea comprises vast unexplored areas and is expected to conceal significant undescribed invertebrate species diversity. Deep waters may act as a refuge for many relictual groups, including elusive and enigmatic higher taxa, but the evolutionary pathways by which colonization of the deep sea has occurred have scarcely been investigated. Sister group relationships between shallow water an...

This paper presents a study on controlling the out-of-water motion of amphibious multi-rotor UAVs using cascade control method based Active Disturbance Rejection Control (ADRC) algorithm. The aim is to overcome challenges time-varying model parameters and complex external disturbances. research involves developing an underwater dynamic analyzing hydrodynamic forces calculate theoretical inertia...

Recent advances in amphibious theory and flexible archetypes are based entirely on the assumption that e-business and write-back caches are not in conflict with XML. after years of extensive research into web browsers, we demonstrate the evaluation of Internet QoS. We disprove that fiber-optic cables and lambda calculus are rarely incompatible.
