The UNEXMIN Georobotics Ltd. from Budapest, Hungary and the Hranický Kras unit of the Czech Speleological Society joined forces to explore the world’s currently known deepest flooded cave, the Hranická Propast in the Czech Republic, with the UX1-Neo AUV. Within this framework, the international team of the UNEXUP EIT RawMaterials project and the local speleologists, with the support of the Czech firefighters and special rescue units, started the work at the end of July after preparing the field.
The Czech Speleological Society has been investigating the area of Hranická propast for decades. Previous dives by divers and diving robots reached a depth of 404 m. The main goal of this year’s research was high-precision 3D mapping of the upper part of the cave.
