Embodiment Construction

[0074] Originals shown in several different figures are assigned the same and unique reference numerals.

[0075] The three directions X, Y and Z that are orthogonal to each other are in Figure 1-4 shown in .

[0076] The first direction X is called the longitudinal direction. The term "longitudinal" refers to all directions parallel to the first direction X.

[0077] The second direction Y is called the transverse direction. The term "lateral direction" refers to all directions parallel to the second direction Y.

[0078] Finally, the third direction, Z, is called the lift direction. The term "lifting direction" refers to all directions parallel to the third direction Z.

[0079] Such as figure 1 As shown, the invention thus relates to a multi-rotor drone 1 . Such a drone 1 thus comprises a support frame 2 and, for example, four separate electric motors 3 , 13 , 23 , 33 integrally connected to the support frame 2 .

[0080] In this case, the UAV 1 thus comprises four...

Abstract

The present invention relates to a multirotor drone provided with a peripheral protection device and a method for controlling such a multirotor drone. The multirotor drone comprises a carrier frame, at least two propulsion and / or lift rotors and a continuous peripheral protection device laterally protecting the at at least two rotors during a collision of the drone with an obstacle arranged laterally with respect to a direction in elevation Z, the continuous peripheral protection device comprising a peripheral outer wall capable of deforming elastically under the effect of a reaction force F exerted by the obstacle on the peripheral outer wall during the collision. Such drone comprises at least two deformation sensors arranged at the peripheral outer wall, each deformation sensor being able to perform measurements varying as a function of a deformation of the peripheral outer wall, a processing unit connected to the at least two deformation sensors, and an operating device for generating operating commands for the at least two rotors.

Description

technical field [0001] The invention relates to a multi-rotor UAV equipped with a protection device for preventing the rotor from colliding with obstacles. Therefore, the drone may include at least two rotors arranged adjacent to each other and driven to rotate by at least two motors integrally connected to the supporting frame. [0002] More specifically, the invention relates to the field of autonomous driving systems for drones, ie not controlled remotely and not following a route originally prepared and stored in the drone. Background technique [0003] This type of drone can be used in particular for the task of finding injured people or more simply people in danger in buildings that are full of smoke, even burning or where potentially toxic fumes are present. [0004] It is known that there are drones equipped with continuous perimeter protection capable of laterally protecting at least two rotors in the event of a collision. Additionally, systems are known for detec...
