Progress Workshop in Porto

From the 4th of July to the 6th of July, UNEXMIN partners got together for a three-day meeting entitled “Progress Workshop”. As the name indicates, this workshop was a way to control the work being done by every partner in each of the eight work packages, to guarantee that the project is developing in the right way. The meeting was hosted in Porto by INESC TEC at their facilities, which include a robotics development lab.

On the first day of the meeting, there was an overview of the project and a review of the work in each work package. Items included hardware and software developments, preparation for testing the robotic system and communication and dissemination activities. In a multi-disciplinary project like UNEXMIN (robotics, geology, technology development), it is crucial that the different teams share their work with the others. The Advisory Board members – experts in mining and geology – were present during the review of the project and gave their most valuable help to the project partners. Their guidance is very welcome – after all, they have the expertise.

Discussions held during the Progress Workshop

The second day was dedicated to a review meeting of the Work Packages with an evaluator of the European Commission. The evaluator considered the project as running well with everything having been done on time and with good development prospects. After the review, the partners visited INESC TEC robotics labs, where they have a local pool which is used for testing. UPM, who built a UX-1 prototype, tested the robot in the pool, as you can see in the following video.


On Thursday, the core discussions for the development of the multi-robotic system were held. These included discussion on Work Package 3 – Autonomy for mine exploration and mapping, Work Package 4 – Multi-robot platform development, and Work Package 6 – Post-processing and data analysis functions. These work packages started recently, so discussions on their structure and content are of high importance.

There is no time to make mistakes and the consortium is doing their best for the development of the multi-robotic system!

July begins with a UNEXMIN meeting in Porto

The UNEXMIN consortium partners will gather together in Porto, Portugal, from the 4th to the 6th of July. The Advisory Board will be present at this meeting – a group of experts from the industry and academia.

The meeting that will happen next week, entitled “Progress Workshop”, will be very important for the development of the project. The following concepts, essential for the progress of UNEXMIN, will be discussed:

  • Mechanical design of UX-1
  • Building of the first robotic prototype that will start in the Autumn
  • Technical discussions about UX-1
  • Logistics discussions about the UNEXMIN technology and service

Among all the discussions, the technical teams will show the developments they have achieved so far. Like UPM (Universidad Politécnica de Madrid) partners, that will show their laboratory tests with a prototype of UX-1:

Next week there will be great news to share with everyone!

Work begins in the lab on UX-1: Part 2 – University of Miskolc

In one of the latest posts on UNEXMIN, it was presented the work being done by TUT. Now it’s time for another team of the UNEXMIN’s consortium.

The UNIM team comes from the University of Miskolc, Hungary. They are responsible for Work Package 2 “Scientific instrument design and adaptation” and are working one of the most important areas for the future multi-robotic system – building tailor-made instruments that will allow the robot to get the most meaningful geoscientific data possible inside flooded mines.

Many of the spaces designed for the UX-1 submersible will be filled with scientific instruments developed by UNIM

Inside Work Package 2, UNIM is responsible for deliverables such as the “Parameter framework report”, “General interface specification report”, “Laboratory test reports of instrumentation units” and “Real environment test report of instrumentation units”. In short, UNIM has been studying and developing the scientific instruments while testing them in the laboratory and in field conditions. These steps will guarantee that the scientific components work at maximum efficiency in flooded mine environments (confined places, pressure and temperature constraints, etc).

UNIM’s work, which started right in the beginning of the project, can, in a nutshell, be described as defining, adapting, testing and calibrating the various scientific instruments (see the list below) that the UX-1 robot will carry on board during its missions. The scientific instrumentation was carefully chosen: the consortium had to evaluate considerations from the project stakeholders in what they wanted in the robotic system (user requirements) and various constraints related to the prototype design (i.e. size and weight limitations). These important factors limit the amount of equipment available for the robotic system.

The list of scientific apparatus include:

  • pH unit
  • Electrical conductivity analyser
  • Pressure and temperature analyser
  • Water Sampler
  • Magnetic field measurer
  • Gamma-ray meter
  • Sub-bottom profiler
  • Multispectral camera
  • UV fluorescence unit

The instrumentation listed above can be divided into Water sampling methods (including pH, electrical conductivity, pressure and temperature measurements), Geophysical methods (including Magnetic field, Gamma-ray, Sub-bottom profile measurements) and mineralogical – or optical – methods (including multispectral camera and UV fluorescence measurements). These methods will substitute the impossibility to use direct methods like collect rock samples from mining walls, thus allowing the robot to still get valuable nonscientific data. In a project of this nature, valuable data is everything.

The results of the work being developed by UNIM will be seen when the first robotic prototype UX-1 is ready to be tested in early 2018 – the first test is scheduled for May, in the Kaatiala Mine, Finland.

UNEXMIN during April

In April, UNEXMIN continued to develop, adapt and test instruments for the upcoming UX-1 robotic explorer prototype. Also in progress is the development of data collection, processing and analysis tools. Software development is a critical step, as gathering and processing meaningful data from the flooded mines will be challenging.

During this time, UNEXMIN was also presented and discussed in conferences and other events across Europe. The dissemination agenda is important as it makes the project visible to its target audience of engineers, geologists and other relevant researchers and industries:

EGU General Assembly 2017

UNEXMIN was presented by LPRC on the opening day of EGU 2017. Luís Lopes’ talk reviewed the most important aspects of the project such as the concept and methodology, work developed and in development, and the potential impact and future further developments. 

XXXI MicroCAD MultiScience Conference

UNEXMIN was also delivered as a plenary talk at the international XXXI MicroCAD MultiScience Conference in Hungary. The audience was given an overview of the project, as well as a unique insight into the work being developed by UNEXMIN’s technology-focussed partners.

Led by Claudio Rossi, UNEXMIN’s partners at UPM won a scientific poster competition in an event held by the engineering school. UNEXMIN won this award from a pool of over 160 projects, covering all areas of engineering. Take a look at our award-winning poster here.


Work begins in the lab on UX-1: Part 1 – Tampere University of Technology

The UNEXMIN project is now in its second year. After the first year, where work mainly focussed on preparatory tasks such as research and component-design, the project is now entering its most important phase prior to testing. During this phase, the custom-designed casing and instrumentation hardware will be manufactured and assembled to create the first UX-1 robotic prototype, which is due in the beginning of 2018.

General layout of the future UX-1 robot

Like much of the work done in the previous year, the majority of the workload in the coming months will be centred in the labs of some of the project’s partners, including TUT (Tampere University of Technology), UNIM (University of Miskolc), UPM (Universidad Politécnica de Madrid), INESC TEC (Instituto de Engenharia de Sistemas e Computadores, Tecnologia e Ciência), and RCI (Resources Computing International).

Hands-on lab-work is essential in UNEXMIN, where we are creating a new technology that will be capable of autonomously exploring and mapping flooded mines. For the success of the project, our team has to continually conduct research and testing and implement necessary modifications. Everything must be optimised and fine-tuned if all the equipment, such as the on-board computer, batteries, and thrusters, is to fit inside the spherical robotic prototype.

The work of TUT (Tampere University of Technology), one of the project’s leading partners, is mainly centred on the development of the robotics components of UX-1. TUT are responsible for a total of 10 predefined deliverables including ‘Robotic Platform Prototype requirement specifications‘, ‘Robotic Platform Prototype technical and mission specifications‘, and ‘Stakeholder-requirement specifications‘. Among their various other responsibilities, these deliverables are essential for the development of the robotic prototype and the definition of its available services.

Since the beginning of the project, Jussi Aaltonen‘s team at TUT have been working on the definition of the robotics specifications that will serve has the base for construction the UX-1 prototypes. To date, TUT have designed and tested key robotics features necessary for implementation in flooded underground mines. TUT’s activities have included pool tests at their testing pool using a plastic mock-up of UX-1, functionality testing of robotics equipment in the laboratory, and also software and hardware testing.

The TUT team is currently finalising the technical specifications and mechanical design of the prototype, as well as building the pressure hull that will support the internal components of the robotics system. Fabrication of the pressure hull components will begin shortly, once the final mechanical analyses are complete. The first UX-1 prototype will be ready at the beginning of 2018!
