The UX robot-based exploration technology for underground flooded environments



UX-1Neo is the upscaling version of the former UX-1, developed in the UNEXMIN project (2016-2019). The project representatives collected feedback and requirements from potential customers, together with the analysis of malfunctions/limitations found in the previous robot to make this new, improved version.

Both robots share the same dimensions and functionalities, however, UX-1Neo is a lighter, modular vehicle with better hardware, software, and geoscientific instruments. These improvements resulted in a more versatile and effective robot in the field, with more productive and cost-effective missions!

The robot was developed in 2020, and it is the first robot built within the UNEXUP project. Now it is ready to perform underwater surveying missions in the EU and worldwide, and collect valuable geoscientific and spatial data from these sites.

An updgraded version of UX-1Neo will be built in 2022. This new version, e.g. UX-2, will comprise sensors and instruments that support depths of over 1 km – due to the modularity of the robot. Therefore, it will will be adapted to address even more challenging underwater missions!
