Dipo: a miniaturized hopping robot via lightweight and compact actuator design for power amplification.

Bioinspiration & biomimetics
Kangaroo rats are well known as representative hoppers in small-scale animals. Especially kangaroo rats show rapid movement when a predator approaches. If this amazing motion can be applied to small-scale robots, they will be able to traverse lands a...

Jumping over fences: why field- and laboratory-based biomechanical studies can and should learn from each other.

The Journal of experimental biology
Locomotor biomechanics faces a core trade-off between laboratory-based and field-based studies. Laboratory conditions offer control over confounding factors, repeatability, and reduced technological challenges, but limit the diversity of animals and ...

Chasing the cheetah: how field biomechanics has evolved to keep up with the fastest land animal.

The Journal of experimental biology
Studying the motion of cheetahs - especially in the wild - is a technically challenging endeavour that pushes the limits of field biomechanics methodology. Consequently, it provides an interesting example of the scientific symbiosis that exists betwe...

Underwater legged robotics: review and perspectives.

Bioinspiration & biomimetics
Nowadays, there is a growing awareness on the social and economic importance of the ocean. In this context, being able to carry out a diverse range of operations underwater is of paramount importance for many industrial sectors as well as for marine ...

A vacuum-actuated soft robot inspired by Drosophila larvae to study kinetics of crawling behaviour.

PloS one
Peristalsis, a motion generated by the propagation of muscular contraction along the body axis, is one of the most common locomotion patterns in limbless animals. While the kinematics of peristalsis has been examined intensively, its kinetics remains...

Robust and reusable self-organized locomotion of legged robots under adaptive physical and neural communications.

Frontiers in neural circuits
INTRODUCTION: Animals such as cattle can achieve versatile and elegant behaviors through automatic sensorimotor coordination. Their self-organized movements convey an impression of adaptability, robustness, and motor memory. However, the adaptive mec...

A Gecko-Inspired Robot with a Flexible Spine Driven by Shape Memory Alloy Springs.

Soft robotics
The majority of sprawling-posture quadrupedal vertebrates, such as geckos and lizards, adopt a cyclical lateral swing pattern of their trunk that is coordinated with limb movements to provide extraordinary flexibility and mobility. Inspired by the ge...

A CPG-Based Versatile Control Framework for Metameric Earthworm-Like Robotic Locomotion.

Advanced science (Weinheim, Baden-Wurttemberg, Germany)
Annelids such as earthworms are considered to have central pattern generators (CPGs) that generate rhythms in neural circuits to coordinate the deformation of body segments for effective locomotion. At present, the states of earthworm-like robot segm...

Comparison of the dynamics of exoskeletal-assisted and unassisted locomotion in an FDA-approved lower extremity device: Controlled experiments and development of a subject-specific virtual simulator.

PloS one
Robotic exoskeletons have considerable, but largely untapped, potential to restore mobility in individuals with neurological disorders, and other conditions that result in partial or complete immobilization. The growing demand for these devices neces...

A novel wave-like crawling robot has excellent swimming capabilities.

Bioinspiration & biomimetics
Multiple animals ranging from micro-meter scale bacteria to meter scale vertebrates rely on undulatory motion to propel themselves on land and in the water. This type of locomotion also appears in amphibious animals such as sea snakes and salamanders...
