UNEXMIN Georobotics Ltd. has released a short film covering the use of the UX1-Neo diving robot’s exploration of the Hranice Abyss, the deepest known freshwater cave on earth.
During the dives, the UX1-Neo explorer ROV (remotely operated vehicle) was used to continuously measure water parameters, create an accurate 3D image of the upper parts of the cave, and give Czech geologists and hydrogeologists a more precise knowledge of the cave’s construction and the debris accumulated there.
The cave’s deepest point was formerly known at 404m, reached by a research robot during a 2016 National Geographic mission which was exclusively aimed at breaking the depth record.
The international team consisting of UNEXMIN Georobotics and its partners in the UNEXUP EIT RawMaterials project, Amphora Diving Club, the Czech Caving Association, the Czech Speleological Society and Czech firefighters and special rescue unit, successfully achieved the original goals set, and set a new world record on August 1, 2022, when the diving robot dived to a depth of 450 m and increased the explored and mapped depth of the cave by 46 meters.
The film shows the construction and testing of the UX-1Neo explorer robot, as well as details of the world record-breaking dive:
