An operation facility for an unmanned aerial vehicle with rotary wing of the present invention includes: a passage space that extends in the up-down direction and is for the ascent and descent of the unmanned aerial vehicle; and an air pressure control system that controls the air pressure in the passage space. The air pressure control system performs control such that the air pressure above the unmanned aerial vehicle is lower than the air pressure below the unmanned aerial vehicle.

An apparatus, including a drone which is assigned to a venue and programmed or configured for flight, navigation, or operation, within an interior of the venue. The drone is activated upon an occurrence of a drone activation event, and the drone flies or navigates inside the venue in response to the drone activation event. The drone finds or locates an individual or an animal inside the venue, and initiates a communication link with a communication device, wherein the communication device is located at a location remote from the venue. An audio recording device or a video recording device of or at the drone records audio information or video information, and the drone transmits the audio information or the video information to the communication device or to a computer. The computer is located at a location remote from the venue. The drone provides audio information via a speaker.

An unmanned ground-based system is disclosed which includes a chassis, a plurality of wheels coupled to the chassis and configured to allow the chassis to move about a surface, a plurality of propeller assemblies configured to provide on-ground motion propulsions, a boom having a boom propeller assembly with a propeller disposed on a plane generally perpendicular to the plurality of propeller assemblies, configured to independently and selectively provide positive and negative rectilinear thrust vectors, and an end-effector coupled to a distal end of the boom, the end-effector having a force sensor configured to provide contact force between the end-effector and an object, wherein the contact force is used as a feedback signal to determine magnitude of the positive and negative rectilinear thrust vectors that is generated by the propeller of the boom propeller assembly.

A flight speaker 1 firstly outputs an inspection sound while flying on a first route R1 in a linear shape connecting a position of a sound collecting microphone M disposed inside a concert hall P1, and identifies an optimal volume position where a volume of a received sound collected by the sound collecting microphone M becomes an expected volume. The flight speaker 1 outputs an inspection sound while flying on a second route R2 in an arc shape with a distance between the identified optimal volume position and a position of the sound collecting microphone M as a diameter, and identifies an output position where a sound waveform of the received sound from the sound collecting microphone M becomes an expected sound waveform.

An example customer assistance system and associated methods are described. The example customer assistance system includes a shopping cart, a customer assistance unit mounted on the shopping cart, and a location system disposed remotely from the shopping cart and the customer assistance unit. The customer assistance unit includes a light source oriented upwards relative to horizontal, and an actuator for actuating the light source into an illumination position. In the illumination position, the light source projects a light beam over the shopping cart. The locating system includes at least one image capturing device configured to scan a ceiling for the light beam and to determine a source location of the shopping cart based on a ceiling location of the light beam.
