Exyn’s LiDAR drones achieved autonomy level 4 and are now capable of mapping and surveying complex underground mines on their own – without a pilot. To better understand what the different levels of autonomy mean, Exyn created this chart:
Exyn says they have reached Level 4A – a stage where the drone becomes completely self-reliant for open-ended exploration and does not require any human interaction during flight. In ideal conditions, Exyn’s LiDAR drones can fly at up to 2 m/s and cover 16 million cubic meters in a single flight.
