UNEXMIN next stop: Urgeiriça mine, Portugal

The UNEXMIN technical teams are on their way to Portugal in preparation of the third set of field trials linked to the project. This is set to happen between the months of March and April in the Urgeiriça uranium mine, Portugal. The novelty of this trial will be the presence of two UX-1 robots to explore and map the flooded part of the mine.

After the first two UNEXMIN field trials, at the Kaatiala mine and at the Idrija mine, it is once again time for the robotic and instrumentation developers to go to the field for one more trial. The third elected place to explore is a closed flooded mine in the centre of Portugal, the Urgeiriça uranium mine, once a very important source of radium and uranium. Here, the team will aim at exploring and mapping the three main shafts and tunnels, representing a more difficult environment to navigate and map when compared to its test site predecessors. Difficulty in operations will be characterised by the presence of two UX-1 robots operating within the waters of the mine: UX-1a and UX-1b.

The next robot UX-1b – from a final platform of 3 working prototypes – is currently being assembled and pre-tested in Porto at INESC TEC’s testing pool. Having two robots within the exploration and mapping platform gives security of operations, while at the same time, distributing the scientific payload through the surveyors, which translates into reduced size, weight and power demands of the individual UX-1 robots: one of the major benefits (and demands!) of the UNEXMIN robotic platform.
