Fail-Safe Features

In case battery drops to a critical limit or contact is lost with the UAV, emergency failsafe procedures will be executed. They allow to ensure system’s integrity automatically like by performing automatic emergency landings.

Current multicopter fail-safe protocols respond with pre-programmed behaviors that aim to minimize possible damage to the aircraft or avoid risk to the nearby population. Existing fail-safe protocols for multicopters involve either returning to a pre-designated home point or executing an automatic landing protocol. Such strategies are rigid
and can even increase risk in cases with complex terrain or high overflown population densities.This paper examines three alternative fail-safe protocols for autonomous urban multicopter flight that trade the simplicity of existing protocols with responsiveness to terrain, multicopter state, and overflown population. We utilize nontraditional data and sensor fusion to make an informed landing site selection with a focus on building rooftops as safe urban landing sites. The first protocol assigns a “Clearance to Land” flag to all buildings to determine the nearest rooftop in the area that can serve as a feasible landing site. The second protocol first determines a possible landing site within the multicopter’s reachable footprint using lot types provided by a property database. During traversal to that site the multicopter examines the rooftops of overflown buildings and generates an alternative landing plan if it discovers a viable rooftop not previously mapped. The third protocol utilizes the known building locations and their approximate geometries as specified by the database to generate a spanning tree coverage solution followed by the multicopter to search for a viable landing site.
