A popular approach to designing robots that can navigate a world built for living creatures is to simply copy Mother Nature’s designs. But while trying to improve how a six-legged robot walks, researchers at the École Polytechnique Fédérale de Lausanne actually found a faster way for six-legged creatures to get around. While many vertebrates are able to run quickly and with minimal ground contact, six-legged insects take a different approach to speed. They use what’s called a tripod gait, which means that when scurrying across flat terrain, they always have at least three legs touching the ground—two on one side, and one on the other.
Code.org, which started offering an advanced placement computer science principles this school year in partnership with The College Board, could more than double the number of underrepresented minorities enrolled in AP computer science classes across the nation. During the last school year, 8,442 underrepresented minorities (black, Latinx, American Indian/Alaska Native, Native Hawaiian/Other Pacific Islander) took the AP Computer science test in the U.S., according to The College Board. For the sake of comparison, 15,913 Asian students and 26,698 white students took the AP CS exam last school year, while just 2,027 black students and 6,256 latinx students took the exam
