According to Fox News, MITâs cheetah robot can now jump over obstacles up to 18 inches tall, which is more than half the robotâs height. âOur goal is to use this kind of robot to save lives in a disaster situation,â explains Professor Sangbae Kim.
The adult cheetah weighs from 21 to 72 kg (46 to 160 lb). Its total head-and-body length is from 110 to 150 cm (43 to 59 in), while the tail can measure 60 to 84 cm (24 to 33 in) in length Cheetahs are 66 to 94 cm (26 to 37 in) tall at the shoulder.he coarse, short fur of the cheetah is tan with round black spots measuring from 2 to 3 cm across, affording it some camouflage while hunting. There are no spots on its white underside, but the tail has spots, which merge to form four to six dark rings at the end.
