The Multiscope equipped with 3D LiDARs was used in the Estonia Mine in
closed underground locations. As the anchor structure used to support
the ceiling is removed after the end of mining operations, people are no
longer allowed to enter those areas.
“Enefit uses smart and innovative solutions to make our production more
efficient, to minimize our environmental impact, and prevent
occupational safety-related risks. An unmanned vehicle is an excellent
solution for conducting surveys in an area which may be unsafe or
prohibited for people to enter,” said Veljo Aleksandrov, Development
Project Director at Enefit. “The vehicle’s mission was successful – we
obtained the three-dimensional images and other necessary data which are
vital for building a solar power plant on top of the mine,” added
Enefit is planning on building one of the largest solar power plants of
the region on top of the abandoned mine which will be generating
approximately 3,500 MWh of renewable electricity per year.
“The engineers of Milrem Robotics are working on different robotics
solutions designed for the civil market. Above all, they are focusing on
autonomous movement in complicated environments. Multiscope is a good
example of how our technology helps to increase efficiency and complete
complex tasks,” said Kuldar Väärsi, CEO of Milrem Robotics.
For this mission the Multiscope was piloted underground using data
coming from LiDARs and wide spectrum HDR cameras, however, autonomous
operation can be applied in future projects.
This was the first time the conditions in a closed room block were
examined in this manner, Enefit stated.
