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 70-lb robot (roughly the same weight as a female cheetah) estimates the height, size, and distance of objects in its path, and adjusts its approach to prepare a jump and safe landingâall without slowing down. âItâs the first legged robot to be able leap hurdles like this autonomously,â says team leader Sangbae Kim.
