Learning quadrupedal locomotion over challenging terrain (2020, neutral): “This is narrower than the range of gait patterns found by quadrupeds in nature (33).”
Heuristic Planning for Rough Terrain Locomotion in Presence of External Disturbances and Variable Perception Quality (2018, background): “…is adjusted to the minimum coming from the three velocity components: When a new value of T cycle is computed, the durations of the body and swing trajectories are recomputed as T mb = ( T cycle − T lu ) D and T sw = ( T cycle − T lu )( 1 − D ) respectively, according to the duty factor D [39].”
Anisotropic Friction of the Ventral Scales in the Snake Lampropeltis getula californiae (2014, background): “Backward slipping of the snake is prevented by pushing its body to irregularities and asperities of the ground [52].”
Origin of Human Bipedalism As an Adaptation for Locomotion on Flexible Branches (2007, background): “However, straightlimbed bipedality is characteristic of normal modern humanwalking, where it reduces the joint moments required to exert locomotor forces and enables energy savings by pendulumlike transformations between potential and kinetic energies (18).”
Biorobotics: Using robots to emulate and investigate agile locomotion (2014, background): “the cost of transport, the Froude number, and the Stroudhal number (24).”
Optimizing Locomotion Controllers Using Biologically-Based Actuators and Objectives (2012, methodology): “To produce gaits that have a high degree of realism, we employ an objective based on minimization of metabolic energy expenditure, thus choosing the most effortless gait that achieves the task [Alexander 2003].”
Moving towards acceleration for estimates of activity-specific metabolic rate in free-living animals: the case of the cormorant. (2006, background): “and judicious expenditure, mediated via movement of body parts (e.g. in locomotion; Alexander 2003) or”
Carbon export mediated by mesopelagic fishes in the northeast Pacific Ocean (2013, background): “5 (Alexander, 2003), and fishes swim at 2 BL s 1 with a vertical velocity 5 cm s (1), then the VM fish now spends 4 h d 1 travelling vertically with an elevated metabolic rate equivalent to 6.”
Killer whale predation on bluefin tuna: exploring the hypothesis of the endurance-exhaustion technique (2007, background): “In summary, the present study suggests that similar to some terrestrial carnivores such as African hunting dogs Lycaon pictus, which pursue their prey until it drops from exhaustion (Alexander 2002), killer whales rely on endurance to catch tuna rather than on sprinting speed.”
State-dependent Energy Allocation in Cod (Gadus Morhua) (2006, background): “45 326 (Alexander 2003), but we have not been able to find more exact determinations of overall 327 metabolic pathways of relevance to this model.”
A Bipedal Walking Robot with Efficient and Human-Like Gait (2005, background): “A key issue in locomotion is energy use [13].”
