In March 2022 the technology developers and robot operators re-visited Ecton mine, for the second UNEXUP field work of the year. The purpose of the visit was to further explore the mine shafts in the United Kingdom.

The underwater exploration of Ecton started in 2019, during the UNEXMIN project, with the UX-1 robots. Now, in 2022, the work continues with the novel UX-1Neo.

The robot collected spatial data with sonars and lasers, which allowed the volumetric calculations of the mine chambers. In addition, it continuously measured water parameters such as pH, EC, temperature, oxygen fugacity and pressure of the water.

UX-1Neo dived in two shafts and explored parts of the mine workings that have been unknown for more than 150 years. Due to the crystal clear waters, high-resolution, 3D photogrammetric models were made.
