Stable Imitation of Multigait and Bipedal Motions for Quadrupedal Robots Over Uneven Terrains

Advanced Robotics Research, EarlyView.
How are quadrupedal robots empowered to execute complex navigation tasks, including multigait and bipedal motions? Challenges in stability and real‐world adaptation persist, especially with uneven terrains and disturbances. This article presents an imitation learning framework that enhances adaptability and robustness by incorporating long short‐term ...

Phenotypic characterization of draft donkeys within the Sudano-Sahelian zone of Cameroon [PDF]

, 1998
Data on age, sex, coat color, liveweight (LW), heart girth (HG), trunk length (TL) and height-at-withers (HW) for 743 donkeys within the Sudano-Sahelian region of Cameroon were recorded. The ages of the donkeys ranged from 0 to 13 years.

An exploration of the influence of diagonal dissociation and moderate changes in speed on locomotor parameters in trotting horses [PDF]

, 2016
Background. Although the trot is described as a diagonal gait, contacts of the diagonal pairs of hooves are not usually perfectly synchronized. Although subtle, the timing dissociation between contacts of each diagonal pair could have consequences on ...

Molecular-genetic and phenotypic characteristics of desmoid-type fibromatosis

Exosomes, 2019
Desmoid-type fibromatosis (DF) is a rare mesenchymal tumor occurring in only 2 to 4 people per 1,000,000 population a year. Desmoid tumors are either seen sporadically or in individuals with familial adenomatous polyposis (FAP).

Fold Walker: An Origami‐Inspired Quadruped Robot for Multipattern Locomotion and Object Grasping

Advanced Robotics Research, EarlyView.
This article presents Fold Walker, an origami‐inspired quadruped robot capable of multipattern locomotion and object grasping. With each leg featuring two rotational folds, the robot can transform from a flat 2D configuration into complex 3D poses. Furthermore, its trunk and legs can be one‐shot 3D printed as a unified structure, greatly simplifying ...

Validation of distal limb mounted inertial measurement unit sensors for stride detection in Warmblood horses at walk and trot [PDF]

, 2016
Background: Inertial measurement unit (IMU) sensor-based techniques are becoming more popular in horses as a tool for objective locomotor assessment. Objectives: To describe, evaluate and validate a method of stride detection and quantification at walk ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Reorganisation ofHoxdregulatory landscapes during the evolution of a snake-like body plan [PDF]

, 2016
Within land vertebrate species, snakes display extreme variations in their body plan, characterized by the absence of limbs and an elongated morphology. Such a particular interpretation of the basic vertebrate body architecture has often been associated ...

Asymmetry in Skipping Enhances Viability Against Control Input Noise

Advanced Robotics Research, EarlyView.
Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...

A Canine Musculoskeletal Robot for Investigating Biomechanical Functions During Locomotion

Advanced Robotics Research, EarlyView.
In this study, a dog limb musculoskeletal robot was developed using thin McKibben artificial muscles to investigate the effects of the dog's musculoskeletal structure on walking. Walking experiments were conducted in both indoor and outdoor environments, suggesting that the flexible structure of the dog's shoulders contributes to an increase in stroke ...
