Robot volcanology

Earlier this week, we talked about Raspberry Pi robots under the sofa. Today, we’ve got a Raspberry Pi robot under a volcano to show you.

Dr Carolyn Parcheta studied volcanology in Hawaii, and now works as a NASA postdoctoral fellow in Pasadena. Her particular area of study is the geometry of volcanic fissure vents: something that’s very hard to map, because they’re inaccessibly narrow, coated with sharp glass from eruptions, and are often destroyed when magma flows through them.

Learning about that geometry is crucial in building an understanding of how eruptions work: how magma flows, and how gas escapes. So with the help of a Raspberry Pi, Dr Parcheta has built a wall-climbing robot to go where humans can’t, and is using it to model cracks and vents in much more detail than has been possible before.

She made this video about the project for a National Geographic award last month, where she placed in the finals.

Dr Parcheta’s eventual goal is to 3d-map all of the fissures in Kilauea, an active volcano on Hawaii. There are 54 in all, and she completed maps of two in May this year. We’ll be keeping an eye on her progress – and on the progress of that brave little robot!
