  • quadruped walking - Jim Usherwood Research
    Quadrupeds walk with a duty factor above 1 2 (each foot is on the ground for more than half the stride cycle), but with a range of phases between back and front feet THIS PAPER describes how the phasing observed, and how it relates to duty factor, matches mechanical work minimisation
  • Evolutionary history of quadrupedal walking gaits shows mammalian . . .
    Considering the evolutionary history of quadrupedal gait sequences has provided a new framework for investigating patterns of quadrupedal locomotor strategies and has highlighted the degree to which mammals have achieved locomotor diversity in contrast to other extant quadrupedal animals
  • A GUIDE TO QUADRUPEDS’ GAITS - Walk, amble, trot . . . - Animator Notebook
    You’ll find an analysis of footfalls of the most common quadrupeds’ gaits, including which animals each gait suits best Here, I analyze all six gaits in the order of the speed they provide the animal: walk, amble, trot, pace, canter, and gallop
  • (PDF) Biomechanics of quadrupedal walking: how do four-legged animals . . .
    We find that two factors can explain how dogs, and probably many other quadrupedal animals, can produce inverted pendulum-like movements First, dogs walk with a limb phase of 15% rather than 25%, which prevents the fore and hind quarters from Determinants of the vertical displacements of the fore and hind quarters We find that a dog’s fore
  • Biomechanics of quadrupedal walking: how do four-legged . . . - PubMed
    Our goal was to understand how the limbs of walking quadrupeds coordinate the vertical movements of the fore and hind quarters to produce these inverted pendulum-like movements We collected kinematic and ground reaction force data from dogs walking over a range of speeds
  • Biomechanics of quadrupedal walking: how do four-legged animals achieve . . .
    Summary Walking involves a cyclic exchange of gravitational potential energy and kinetic energy of the center of mass Our goal was to understand how the limbs of walking quadrupeds coordinate the vertical movements of the fore and hind quarters to produce these inverted pendulum-like movements
  • Quadrupedal - SpringerLink
    Quadrupedal locomotion encapsulates any form of progression in which four limbs support and propel the body Quadrupedal movement represents the basal condition for all tetrapods and as such remains the most commonly utilized form of locomotion (see Fig 1 and Granatosky 2018 for data on mammals)
  • Evolutionary history of quadrupedal walking gaits shows mammalian . . .
    patterns that drove gait evolution in quadrupedal animals is insufficient Here, we use crowd-sourced data and phylogenetic comparative methods to provide the first explicit macro-evolutionary tests of hypotheses regarding the evolution of quadrupedal walking gaits in gnathostomes, using the phylo-
  • Typical 4 Phases of Quadruped motion showing various . . . - ResearchGate
    In this paper, a detailed overview of the animal motion and analysis of various gaits of each quadruped character is discussed The three animal characters under study are Lion, Cat and Tiger,
