Jumping spider inspires novel image-based distance sensor

Harvard University has been inspired by a jumping spider to develop a novel distance sensor. The spider (family salticidae) hunts by ambushing prey, leaping onto it from a distance, and to do this it has to leap the correct distance. Unlike humans which use two-eye binocular vision (amongst other visual effects) to estimate range, the ...
