Researchers made a robotic dinosaur skeleton run on a treadmill. Here's what they learned.
Gliding is a form of flight that was associated with both dinosaurs and birds, but there's mounting evidence that both would flap their wings for flight, too. How did that evolve?The study, published Thursday in the journal PLOS Computational Biology, suggests that winged two-legged dinosaurs may have learned to flap their wings as a side effect of running.
5 and 13 miles per hour, vibrations would have caused the wings to flap, according to the study.The researchers explored their idea further by building a robot of a life-size Caudipteryx skeleton and having it run on a treadmill. They were able to see the flapping motion of the wings at different speeds, as they had calculated.A Caudipteryx robot built for testing passive flapping flight.
