New AMICOS movie

You can now enjoy a new short movie summarising the recent effects of our work on developing prototypes of mobile inspection robots in the scope of the AMICOS project, and trying them out in various scenarios. The potential of implementing mobile robotics in the assessment of technical conditions of underground mines’ infrastructure is difficult to overestimate, but a lot of work must be still done to utilise the possibilities, which the newest technological advancements give us. In the AMICOS project, we create a fertile ground for the introduction of autonomous UAVs and UGVs in the raw materials sector to be used in smart mapping and inspection missions in the underground environment. The use-cases presented in the movie, are:

  • detection of malfunctioning idlers of a belt conveyor,
  • general inspection of infrastructure used for crushing and transportation of excavated material,
  • detection of humans with RGB and IR cameras based on state-of-the-art AI algorithms,
  • simultaneous localization and mapping (SLAM) performed in underground corridors,
  • creation of interactive maps with the use of data acquired by a mobile robotic platform.

Lower-Silesian Festival of Knowledge with DMC

And once again DMC organised a worshop on digitisation and robotics in mining for university-, school-students, and others interested in innovations in the raw materials sector. For three days Adam Wróblewski and I (Mateusz Góralczyk) held virtual meetings to tell our visitors what is happening in our labs, how digital transformation of raw materials industry progresses, what robots, drones, IoT and cloud computing has to do with mining – all in the form of case-studies from AMICOS, SafeMe4Mine, OPMO, MEITIM, and MOIRA.

Some of the fascinating topics undertaken during our meetings were: how smart apps will help inspectors to ensure productivity and safety in open-pit, and underground mines, how a 3D model of a belt conveyor or an underground corridor can be created with the help of a drone carrying a digital camera or LIDAR, how we can use remotely controlled robots to identify damages of mechanical components, or to find a human in case of emergency.
