An aerial vehicle safety apparatus includes a safety mechanism, a drive mechanism, an ejection mechanism, and a control mechanism. The safety mechanism is used for securing safety of at least one of an aerial vehicle and an object outside the aerial vehicle. The drive mechanism includes at least one drive unit serving as a drive source of the safety mechanism. The ejection mechanism ejects the drive mechanism together with the safety mechanism. The control mechanism controls operations of the drive mechanism for the drive mechanism to drive the safety mechanism after the ejection mechanism starts ejection of the safety mechanism.

A system includes a plurality of vehicles and an unmanned aerial vehicle (UAV) configured to land on one of the vehicles and travel together with the vehicle. A control center selects one of the vehicles on which landing of the UAV is performed based on travel routes transmitted by the vehicles and the UAV, and transmit a cooperation request to the selected vehicle.

To provide an unmanned rotorcraft and a method for measuring a distance to a circumjacent objet around the rotorcraft, enabling it to prevent its airframe from colliding with a circumjacent object when flying and prevent its airframe from falling down when landing, while suppressing an increase in airframe cost. This is solved by an unmanned rotorcraft including a distance sensor to measure a distance between its airframe and a circumjacent object around it, the distance sensor and its detection direction being fixed to the airframe, and a method for measuring a distance to a circumjacent objet around the rotorcraft, adapted to watch or watch out for a circumjacent object around the airframe by turning the airframe automatically in a yaw direction under predefined conditions or to measure a difference of elevation at landing points of all legs of the airframe.

An industrial activity drone comprising an aerial vehicle having at least one rotor, an activity system, and a fastener device for fastening the activity system to the aerial vehicle. The activity system includes a structure, a computer, a work camera that is stationary relative to the aerial vehicle and that provides a view of a work zone, a distribution device having a plurality of compartments, and a turning motor enabling the distribution device to turn relative to the aerial vehicle. The industrial activity drone performs hovering flight so that the work camera faces a work zone and the distribution device is turned so that the compartment that is to be used faces the work zone, thereby performing one or more tasks.

An unmanned aerial vehicle (UAV) includes a vehicle body and a multi-ocular imaging assembly. The multi-ocular imaging assembly includes at least two imaging devices disposed in and fixed to the vehicle body.

A rotor blade rotation system includes two or more rotor blades, each rotor blade in mechanical communication with a hub and pivotable about an axis of rotation, a bearing plate comprising a rotating portion and a non-rotating portion, a fold linkage coupled to the rotating portion of the bearing plate and in mechanical communication with the rotor blade, and an actuator coupled to the non-rotating portion of the bearing plate and operable to reposition the bearing plate from a first position to a second position such that the folding links pivot the rotor blades from a deployed position to a forward folded position.

A robotic vehicle for traversing surfaces comprises a chassis having a plurality of wheels mounted thereto. Two magnetic drive wheels are spaced apart in a lateral direction and rotate about a rotational axis while a stabilizing wheel is provided in front of or behind the two drive wheels. The drive wheels are configured to be driven independently, thereby driving and steering the vehicle along the surface. The vehicle also includes a sensor probe assembly that is supported by the chassis and configured to take measurements of the surface being traversed. In accordance with a salient aspect, the vehicle includes a probe normalization mechanism that is configured to determine the surface curvature and adjust the orientation of the probe transducer as a function of the curvature of the surface, thereby maintaining the probe at the preferred inspection angle irrespective of changes in the surface curvature with vehicle movement.

An unmanned aerial vehicle (UAV) for landing and perching on a curved ferromagnetic surface is provided. The UAV includes a plurality of articulated legs. Each articulated leg includes: a magnet configured to magnetically attach to the curved ferromagnetic surface; and a magnetic foot for housing the magnet and configured to magnetically articulate towards and attach to the curved ferromagnetic surface using the magnet in a perpendicular orientation with respect to the curved ferromagnetic surface, in response to the UAV approaching the curved ferromagnetic surface, in order to land the UAV on the curved ferromagnetic surface and for the UAV to perch on the curved ferromagnetic surface after the landing. The magnetic foot is configured to remain magnetically attached to the curved ferromagnetic surface while the UAV is perched on the curved ferromagnetic surface.

An unmanned aerial vehicle (UAV) includes a body constructed to enable the UAV to fly and three or more legs connected to the body and configured to land and perch the UAV on a curved ferromagnetic surface. Each leg includes a first portion connected to the body, a second portion including a magnet and configured to magnetically attach and maintain the magnetic attachment of the leg to the ferromagnetic surface during the landing and perching, and a passive articulation joint connecting the first and second portions and configured to passively articulate the second portion with respect to the first portion in response to the second portion approaching the ferromagnetic surface. The UAV further includes a releasable crawler including magnetic wheels which detach the crawler from the body during the perching and maneuver the crawler on the ferromagnetic surface while magnetically attaching the crawler to the ferromagnetic surface after detachment.

An unmanned aerial vehicle (UAV) autonomously perching on a curved surface from a starting position is provided. The UAV includes: a 3D depth camera configured to capture and output 3D point clouds of scenes from the UAV including the curved surface; a 2D LIDAR system configured to capture and output 2D slices of the scenes; and a control circuit. The control circuit is configured to: control the depth camera and the LIDAR system to capture the 3D point clouds and the 2D slices, respectively, of the scenes; input the captured 3D point clouds from the depth camera and the captured 2D slices from the LIDAR system; autonomously detect and localize the curved surface using the captured 3D point clouds and 2D slices; and autonomously direct the UAV from the starting position to a landing position on the curved surface based on the autonomous detection and localization of the curved surface.
