VolcanoBot is a two-wheeled robot, about a foot long and just under seven inches tall. It is capable of sending back information about the now empty fissures that once conducted magma up towards the surface. On its first trip down into Kilauea in May of last year, it went 82 feet below the surface, but researchers hope that it (or its successor) will eventually travel much further. Mapping out inactive fissures helps scientists understand how magma travels to the surface, and could help them figure out how eruptions occur.
