Ever wonder how the earliest land animals moved? If so, you’ll be glad to know that scientists, led by evolutionary biologist John Nyakatura at Humboldt University in Berlin, have used a 290-million-year old fossil skeleton to create a moving robot model of prehistoric life. This four-legged plant-eater lived before the dinosaurs and believed to be called a “stem amniote”, or an early land-dwelling animal that later evolved into modern mammals. It fascinates scientists “because of its position on the tree of life,” said Nyakatura. The team partnered with robotics expert Kamilo Melo at the Swiss Federal Institute of Technology in Lausanne to develop a model of how the creature moved before building OroBOT. This robot is made of motors connected by 3D-printed plastic and steel parts and “helps us to test real-world dynamics, to account for gravity and friction,” said Melo.
