Disclosed is an unmanned aerial vehicle adapted to be positioned against a substantially vertical wall while hovering in the air, including a body and rotors, an arm end, a first leg end and a second leg end intersected by a front plane and adapted for together contacting the wall at three spaced apart positions, the front plane intersecting a vertical axis of the UAV at an upper side of a first plane spanned by a lateral and longitudinal axis of the UAV, the front plane extending at a first angle of between 45 to 85 degrees to the first plane; wherein the UAV is adapted for tilting upon contact of the first and second leg ends with the wall while the arm end approaches the wall, about the first and second leg ends and towards the wall, until the arm end contacts the wall.

An unmanned aircraft 1 according to an embodiment of the present invention provides an unmanned aircraft that properly makes a forced landing in case of an abnormality. The unmanned aircraft 1 is configured as a multicopter that flies with lift and thrust generated by rotation of six rotors 13. The unmanned aircraft 1 identifies a forced landing site in a case of having detected an abnormality during flight and controls motors 12 configured to drive the respective rotors 13, to make a landing at the identified forced landing site. The unmanned aircraft 1 is consequently enabled to make an autonomous forced landing at a specific site in case of an abnormality.

We describe an aircraft design, which is capable of vertical takeoff and landing and also high-speed cruise on a fixed wing. The aircraft comprises a fuselage with a probe-deployment mechanism, which deploys a sample-gathering probe, located at a front end of the fuselage. A main wing is coupled to a middle section of the fuselage, wherein a right motor and right propeller are coupled to a right side of the main wing, and a left motor and left propeller are coupled to a left side of the main wing. The right and left propellers are angled with respect to the fuselage enabling the aircraft to pitch up to a vertical-takeoff mode and pitch down a horizontal-cruising mode. A pitch motor and pitch propeller are located at the rear end of the fuselage, wherein the pitch propeller is angled to provide substantially vertical thrust to control a pitch of the fuselage.

According to various embodiments, there is provided a multi-rotor aircraft for a multiple payload delivery comprising a morphing mechanism having an airframe and at least three support arms coupled to the airframe wherein each support arm is configured for rotating about a vertical axis of the aircraft relative to the morphing mechanism. The aircraft further includes a payload bay coupled to the morphing mechanism for engaging and disengaging a plurality of payloads and a control system communicatively coupled with the morphing mechanism and the payload bay, wherein the control system is configured to cause each of the support arms to rotate by a predetermined angle about the vertical axis of the aircraft, wherein the predetermined angle is determined based on a change in distance between a neutral point and a centre of gravity of the aircraft.

Drones convertible into personal computers are disclosed, A disclosed unmanned aerial vehicle (UAV) includes a body and rotors carried by the body. The rotors move relative to the body from a first position when the UAV is in a drone mode to a second position when the UAV is in a computer mode.

An autonomous remote device for deployment in an area, comprising: a mechanism for launching the device airborne from a first of a plurality of locations; a mechanism for navigating the device when airborne to a second of the plurality of locations; and a mechanism for landing the device at the second of the plurality of locations.

An unmanned aerial vehicle is provided in the present disclosure. The unmanned aerial vehicle includes an aircraft body, first arm assemblies disposed at a front of the aircraft body, and second arm assemblies disposed at a rear of the aircraft body. The first arm assemblies include first arms, and the second arm assemblies include second arms. The first arms and the second arms are rotatably connected to the aircraft body respectively, to enable each of the first arms and the second arms to be at an unfolded state or a folded state. When the first arm assemblies and the second arm assemblies are at the folded state, the first arms and the second arms are arranged side by side.

The present disclosure presents various embodiments of a system for retrieving a fixed-wing aircraft from free flight using a flexible capture member. The system includes a GPS reference sensor and a communication link to guide the fixed-wing aircraft to intercept the flexible capture member.

A data storage system that moves and transfers components utilizing drones is disclosed. The data storage system comprises a data storage library for reading and writing of data on a plurality of data storage cartridges, at least one drone vehicle, a processing device, and a non-transitory, computer-readable memory containing programming instructions. The programming instructions are configured to cause the processing device to: receive a request to transfer a data storage component to a destination location in the data storage library, in response to receiving the request, instruct a drone vehicle to perform at least part of the transfer of the data storage component to the destination location, and perform at least part of the transfer of the data storage component to the destination location by the drone vehicle.

An unmanned aerial vehicle having an airframe whose horizontal dimension is efficiently reduced. This object is solved by an unmanned aerial vehicle that includes: a rotor; an arm; and an arm connector. The arm connector includes an arm holder that is a fixing member holding a part of the arm in a longitudinal direction of the arm.
