Cheetah robot lands the running jump (w/ Video)

In a leap for robot development, the MIT researchers who built a robotic cheetah have now trained it to see and jump over hurdles as it runs—making this the first four-legged robot to run and jump over obstacles autonomously.

A robot that runs like a cat (w/ Video)

Thanks to its legs, whose design faithfully reproduces feline morphology, EPFL's 4-legged 'cheetah-cub robot' has the same advantages as its model: It is small, light and fast.

How the cheetah got its stripes—a genetic tale

Feral cats in Northern California have enabled researchers to unlock the biological secret behind a rare, striped cheetah found only in sub-Saharan Africa, according to researchers at the Stanford University School of Medicine, ...

New robot 'Cheetah' breaks land-speed record

(PhysOrg.com) -- Up till now researchers at Boston Dynamics have demonstrated four legged robots that appear meant to carry heavy loads as they tromp through and over rough terrain (e.g. Alpha Dog and Petman, LS3). Now it ...

Ostriches run fast because of 'springy' tendons

Australian and U.S. researchers studying the movement of ostriches have discovered the giant flightless birds can store double the elastic energy per step in their tendons than humans can. This considerably reduces the effort ...

Big cats love Calvin Klein cologne

(PhysOrg.com) -- Workers in Wildlife Conservation Societies around the world are using a new technique to lure big cats to their heat-and-motion-sensitive cameras and keep them there long enough to enable them to be identified. ...

Cheetahs' inner ear is one-of-a-kind, vital to high-speed hunting

The world's fastest land animal, the cheetah, is a successful hunter not only because it is quick, but also because it can hold an incredibly still gaze while pursuing prey. For the first time, researchers have investigated ...

Big cats in evolutionary arms race with prey: study

Lions and cheetah are faster, stronger and no less agile than their prey, but zebras and impalas compensate with a surprising tactic, researchers said Wednesday: slow down, and keep the big cats guessing.

Cheetah

See text.

The cheetah (Acinonyx jubatus) is a large-sized feline (family Felidae) inhabiting most of Africa and parts of the Middle East. The cheetah is the only extant member of the genus Acinonyx, most notable for modifications in the species' paws. As such, it is the only felid with non-retractable claws and pads that, by their scope, disallow gripping (therefore cheetahs cannot climb vertical trees, although they are generally capable of reaching easily accessible branches). The cheetah, however, achieves by far the fastest land speed of any living animal—between 112 and 120 km/h (70 and 75 mph) in short bursts covering distances up to 500 m (1,600 ft), and has the ability to accelerate from 0 to over 100 km/h (62 mph) in three seconds.
