University of Adelaide built a robot spider to scan Australia's Naracoorte Caves

In the southeast of South Australia lie the Naracoorte Caves. The national park is an UNESCO World Heritage Site known for its stalactites, stalagmites and prehistoric fossils. Recently, a group of students from the University of Adelaide built a robot to complete a 3D scan of the site. The project, called CaveX, saw the group create 15 iterations of the model you see above before they settled on a final design. They went with a robot that walks on a set of six legs out of a fear that one with treads or wheels would damage the surface of the caves.
