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

摘要

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 between experimental biology and the technological disciplines that support it. This article uses cheetah motion research as a basis to review the past, present and likely future of field biomechanics. Although the focus is on a specific animal, the methods and challenges discussed are broadly relevant to the study of terrestrial locomotion. We also highlight the external factors contributing to the evolution of this technology, including recent advancements in machine learning, and the influx of interest in cheetah biomechanics from the legged robotics community.
