An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a plurality of shock absorbers provided to the plurality of rotor units; and a main body to which the plurality of rotor units attach. The plurality of rotor units and the plurality of shock absorbers are attachable to and detachable from the main body.

An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a plurality of shock absorbers including a first shock absorber and a second shock absorber different from the first shock absorber, the first shock absorber defining a first gas chamber containing a first gas that is less dense than air; and a release unit that is disposed on the first shock absorber and configured to release the first gas contained in the first gas chamber at a predetermined timing.

An aircraft includes: a plurality of rotor units each including propeller and motor that drives propeller; a shock absorber covering an entire vertical length of a lateral side of the plurality of rotor units; and a plurality of rudders each being disposed downstream of a corresponding one of the plurality of rotor units and rotating about axis of rotation that extends in a direction intersecting a flow direction of air current generated by the corresponding one of the plurality of rotor units.

The present invention provides a flying robot (10) with projector, including a movable end (100) and a fixed end (200). A distributed working mode is used on the movable end (100) and the fixed end (200). The movable end (100) includes a top (110), a main body (120) and a bottom (130). The top (110) includes a lift system (112) and one or more proximity sensors (114); the main body (120) is a sealed hollow spherical body or spheroid body made of a film material capable of being used as a rear projection screen, and is filled with a gas of which the density is less than that of the air. The bottom (130) includes one or more rear projectors (131), a wireless communication module (132), a microcontroller (133), a battery (134), a direction and steering controlling device (135), a camera device (136), a sound capturing and reproduction device (137), a height sensor (138) and other sensors, etc. The fixed end (200) includes a wireless communication module (220), a control apparatus (240), a charging port (260), and other data interfaces, etc. The flying robot (10) with projector according to the present invention facilitates human-machine interaction and is suitable for being used in both indoor and outdoor environments.

The disclosed unmanned aerial vehicle (UAV) includes a buoyant airbag, a drive unit, a retention feature, and an onboard control module that can be configured to cause the drive unit to displace the UAV, cause the retention feature to retain one or more items for transport, and receive instructions to transfer items from one location to another. For example, a UAV can be controlled to obtain an item at one location in a warehouse such as a first floor, lift said item to a second location in the warehouse such as a second floor, and deposit the item at the second location.
