Exyn Technologies says it has signed up Dundee Precious Metals as the first commercial customer for its Autonomy Aerial Robots (A3Rs).Dundee will use the fully autonomous aerial system for data collection in GPS-denied environments to advance its initiatives focused on the digitisation and automation of its underground mining operations, according to Exyn.Theophile Yameogo, Vice President Digital Innovation, Dundee Precious Metals, said, “The Exyn A3Rs allow frequent and hi-resolution mapping of underground environments while reducing risks to personnel.”Yameogo said the company was already very excited at the results of the maps it was seeing. “As we further integrate the A3Rs into our workflow, we anticipate a transformation of operations compared to today’s models,” he added.Exyn’s A3Rs are driven by the company’s proprietary software, exynAI™, a robust commercially available software platform enabling full autonomy for aerial robots. Exyn has deployed its A3Rs as a service for customers in the US, Latin America and Europe.By using Exyn’s aerial robots to automate mapping and surveying, Dundee is, Exyn says, transforming its underground operations in three vital areas:Improving the quality of mapping data captured when compared with traditional surveying techniques;Improving safety by reducing the amount of time spent underground by human operators, and;Increasing operational efficiency by having more accurate and up-to-date information for mine planning.Exyn’s A3Rs operate without the need for a human pilot and in GPS-denied environments. The company said: “They are fully self-contained, intelligent systems designed to operate without the need for any prior information, persistent communication, or GPS. With all intelligence on board, the vehicle is capable of carrying out high-level missions in complex and completely unknown spaces.”Exyn’s multi-sensor data fusion pipeline allows each robot to assimilate measurements from a variety of on-board sensors including 3D LIDAR, cameras, and inertial sensors to “generate a robust state estimate of itself and surrounding environments”.When married with Exyn’s real-time navigation software stack, the robots can safely avoid collisions with both stationary and moving obstacles during requested missions, according to the company. “Moreover, its robots are also able to do real-time Simultaneous Localisation and Mapping to enable highly accurate map generation.”Dundee operates the Chelopech underground copper-gold mine in Bulgaria and is soon to be producing gold at the Krumovgrad project, also in Bulgaria.
