Print Technology Helps Create Robot Dinosaurs 3D

Researchers at Drexel University in bringing the latest three-dimensional printing technology to the study of ancient life. Through these technologies, they can make models of fossils to the actual size.

This is the first time paleontologists or researcher of ancient life, will be able to test hypotheses about how the dinosaurs and other prehistoric animals to move and live in their neighborhood.

"The technology used for 150 years paleontologists have not changed. We use a shovel and pickaxe, then the burlap and plaster. Was not changed until now," said Kenneth Lacovara, Drexel University paleontologist and professor at the College of Arts and Sciences


Lacovara has started to create three-dimensional scanning giant dinosaur bones and other fossils in his laboratory. Scanning three-dimensional virtual image placed in a digital workspace that can be manipulated and analyzed by researchers. To turn your scanned, Lacovara working with mechanical engineer James Tangorra, an assistant professor at Drexel University College of Engineering.

A three-dimensional printer technology is to create a prototype quickly and produce objects based on digital design. A common model exists, works by repeatedly removing a layer of resin or other materials that are very thin and arrange a physical object. The current technology can make a model dinosaur-sized six inches in a few hours.

"It's kind of Star Trek technology, where you can press a button and it will pop up a thing," said Lacovara.

Derived biological modeling to test the possible movement of species extinction is the main focus of the collaboration Lacovara and Tangorra.

"We do not know much about how dinosaurs step. How do they stand, how they move, whether they walk or run, and how do they breed? It's all a bit mysterious," said Lacovara.

But with new technology, researchers can begin testing their predictions for the first time. Lacovara and Tangorra will work together to create a giant sauropod dinosaur robot model, and then install artificial muscles and tendons to perform a comprehensive test of how the animal's body can handle the physical stress of his environment.
