Robots are bringing new life to extinct species

The union of paleontology and robots has its roots in the more established field of bio-inspired robotics, in which scientists fashion robots based on modern animals. Paleo-roboticists, however, face the added complication of designing robotic systems for which there is no living reference. They work around this limitation by abstracting from the next best option, such as a modern descendant or an incomplete fossil record. To help make sure they're on the right track, they might try to derive general features from modern fauna that radiated from a common ancestor on the evolutionary tree. Or they might turn to good ol' physics to home in on the most plausible ways an animal moved.
