Record-Breaking Jumping Robot Can Leap 10-Story Building
Mechanical engineer Sarah Bergbreiter at Carnegie Mellon University said the robot "jumps much higher than most of the rest of the jumping robots in the world do—if not all of them that I'm aware of."

University of California, Santa Barbara researchers have developed a jumping robot that can reach heights of more than 30 meters, or about the height of a 10-story building, after being launched at about 100 kph.
The 30-centimeter tall robot can jump 100 times its own height.
The robot uses elastic power, in which an actuator stores energy in a spring that is released and propels an object in the air, similar to the way a grasshopper's leg muscles work.
However, unlike animals, which have a single contraction to stretch their "spring," the robot uses a motor to store more energy by turning multiple times prior to every jump, and its entire body serves as the spring.
The researchers are working with NASA on further development, in the hope the jumping robot could be used for space exploration.
