The size and arrangement of fibres play a determinate role in the kinetic and energetic
performance of muscles. Extrapolations between fibre architecture and performance …

Animals are much better at running than robots. The difference in performance arises in the
important dimensions of agility, range, and robustness. To understand the underlying …

This paper discusses design and control of a prismatic series elastic actuator with high
mechanical power output in a small and lightweight form factor. A design is introduced that …

The fastest and most manoeuvrable terrestrial animals are found in savannah habitats,
where predators chase and capture running prey. Hunt outcome and success rate are …

Mice are one of the most commonly used laboratory animals, with an extensive array of
disease models in existence, including for many neuromuscular diseases. The hindlimb is of …

The cheetah and racing greyhound are of a similar size and gross morphology and yet the
cheetah is able to achieve a far higher top speed. We compared the kinematics and kinetics …

The large theropod dinosaur Tyrannosaurus rex underwent remarkable changes during its
growth from< 10 kg hatchlings to> 6000 kg adults in< 20 years. These changes raise …

The full publication of Ardipithecus ramidus has particular importance for the origins of
hominin bipedality, and strengthens the growing case for an arboreal origin …

The ability to make behavioural inferences from skeletal remains is critical to understanding
the lifestyles and activities of past human populations and extinct animals. Muscle …

The cheetah is capable of a top speed of 29 ms− 1 compared to the maximum speed of 17
ms− 1 achieved by the racing greyhound. In this study of the hindlimb and in the …
