A method for destroying enemy's targets is disclosed which comprises the following steps: (a) carrying a multicopter drone in a backpack of a first soldier; (b) removing the multicopter drone from the backpack, unfolding, and coupling a missile to the multicopter drone; (c) remote controlling the multicopter drone to search for the enemy' targets using a remote control; and (d) launching the missile from the multicopter drone when the enemy' targets are detected.

An imaging system can include a first and second camera configured to capture first and second sets of oblique images along first and second scan paths, respectively, on an object area. A drive is coupled to a scanning mirror structure, having at least one mirror surface, and configured to rotate the structure about a scan axis based on a scan angle. The first and second cameras each have an optical axis set at an oblique angle to the scan axis and include a respective lens to focus first and second imaging beams reflected from the mirror surface to an image sensor located in each of the cameras. The first and second imaging beams captured by their respective cameras can vary according to the scan angle. Each of the image sensors captures respective sets of oblique images by sampling the imaging beams at first and second values of the scan angle.

An unmanned aerial vehicle comprising an outer protective cage, a propulsion system mounted inside the outer protective cage, a sensor support system fixed on the outer protective cage and a sensor system coupled to the sensor support system. The sensor system is coupled to the sensor support system via a load-limiting coupling mechanism that comprises a spring coupling exerting an elastic bias against the sensor system towards a normal operating position, the sensor system being retractable into the outer protective cage against the elastic bias of the spring coupling upon collision with an external object.

A method for controlling an autonomous unmanned aerial vehicle for delivery of a medication package includes determining a thermal control period for the medication package. The method also includes identifying a delivery location corresponding to the medication package. The method also includes identifying at least one environmental characteristic of an environment that includes a delivery three-dimensional flight path between a starting location and the delivery location, wherein the at least one environmental characteristic indicates an actual weather value at the delivery location. The method also includes determining whether to deliver the medication package based on the thermal control period and the at least one environmental characteristic, using the unmanned aerial vehicle.

Systems, devices, and methods for stopping the rotation of propellers used in unmanned aerial vehicles (UAV) such as drones are disclosed. The propellers are stopped in response to detecting when beams of light adjacent the propellers are blocked.

A dual use UAV or “drone” can include a battery and primary processor located at a fuselage, as well as two separate modular units removably coupled to the fuselage and in communication with the primary processor. The two separate modular units can interact with each other to provide an enhanced operation while the drone is in flight. One modular unit can be an ISR unit having a video camera, and the other modular unit can be a cargo unit. The enhanced operation can involve the ISR unit using its video camera to identify a delivery location for a cargo pod of the cargo unit. Alternative modular units can include a secondary ISR unit, a cargo fuel pod unit, or a robotic arm assembly. Standardized interfaces coupled to the fuselage can enable the ready removal of one modular unit and installation of another one.

A fishing system includes an unmanned aerial vehicle and a fishing line fixing portion placed on a main body of the unmanned aerial vehicle, the fishing line fixing portion including a first fixing portion for fixing a fishing line and a second fixing portion detachably connected to the first fixing portion. The unmanned aerial vehicle includes an imaging device, a fish school tracking processing unit configured to identify a fish in imaging data captured by the imaging device and control the unmanned aerial vehicle to track the fish. A connection between the first fixing portion and the second fixing portion is released when the fish is hooked on an artificial bait attached to a first end of the fishing line.
