In Canada, they created specialized chassis for landing drones on any surface, including sloping ones
The landing gear system includes friction dampers that dissipate excess energy when the drone makes contact with the ground. The drone can also land using special software.
When developing the chassis, the features were taken into accountaircraft landings, in particular, reversing. When the drone needed to land, the propeller blades were launched in the opposite direction. Thanks to this, the drone did not bounce off uneven surfaces.
