Researchers at Johns Hopkins University believe robots could learn a thing or two from nature's most adaptable pest — the cockroach. The insect can navigate almost any terrain, thanks to over 300 million years of evolution. Scientists filmed the cockroaches running obstacle courses and captured their movements using high-speed cameras. The footage was then analyzed and adapted for a six-legged robot to repeat the movements. Researchers hope this work can eventually be used in search and rescue missions during natural disasters.
