Pleurocystitid was a marine organism that existed nearly 450 million years in the past, lengthy earlier than the primary dinosaurs. Scientists have now constructed a soft-bodied robotic reproduction of it, which may encourage new strategies of locomotion for future robots.
Together with its bizarre look, pleurocystitid is thought for being one of many first echinoderms to be able to motion by way of a muscular stem-like appendage. Current-day members of the echinoderm class embrace starfish, sea urchins, sand {dollars} and brittle stars.
Led by professors Phil LeDuc and Carmel Majidi, scientists at Carnegie Mellon College’s Division of Mechanical Engineering lately got down to see precisely how pleurocystitid used its stem to maneuver throughout the ocean flooring. Using fossils as a information, they proceeded to construct a (partially) soft-bodied robotic pleurocystitid with a versatile motorized swishing stem.

When the “paleobionic” system was examined within the lab, the researchers found that large sweeping actions of the stem labored greatest for pushing the robotic ahead. What’s extra, it was additionally discovered that rising the size of the stem considerably boosted the robotic’s pace with out utilizing any extra vitality.
The findings may in the end be used to information the design of robots that rapidly however effectively transfer throughout the ocean flooring or comparable environments. And naturally, the research additionally offers invaluable insights into how marine organisms’ strategies of locomotion have modified over hundreds of thousands of years.
“Bringing a brand new life to one thing that existed practically 500 million years in the past is thrilling in and of itself, however what actually excites us about this breakthrough is how a lot we can be taught from it,” mentioned LeDuc.
The robotic could be seen in motion, within the video beneath.
