Based on an analysis of predator - prey interaction, these panels depict three
strides of a cheetah (blue) trying to hunt down an impala (red).

The scientists think that wild
cheetahs, which boast speeds
of 29 m / s, can use 4
strides per second at their top speeds.
In addition to having longer
stride lengths,
cheetahs can increase the number
of strides they make per second as they accelerate.
As researchers report today in the The International Journal
of Robotics Research,
Cheetah - cub self - adjusts its movement as needed because
of three springs in each leg that adapt dynamically to the irregularities in its
stride.
Smashing a previous record
of 13.1 mph for legged robots, set back in 1989, the concept uses the natural flexing
of both legs and back that a
cheetah exhibits to increase its
stride.
