Flight control for an unmanned aerial vehicle
A lightweight, pocket-sized unmanned aerial vehicle (UAV) that can be held in an outstretched hand by a user for take-off and landing of the UAV. The UAV comprises a semi-toroidal or a substantially toroidal hollow body that defines a duct. The UAV further comprises a motor for rotating a fan that directs air into and out of the duct enabling UAV to take flight. The UAV comprises a flight-control system that comprises at least two flight control surfaces that can alter the directed air as it flows through the duct for controlling the roll and pitch and optionally the yaw of the UAV during flight. The flight control system may be controlled by a microprocessor controller. The UAV further comprises a payload, with at least a wireless transmitter and receiver unit.
1 . A method for controlling an aerial vehicle, the method comprising:
generating an airflow through a duct of the aerial vehicle comprising a body defining the duct;
moving the aerial vehicle along a flight path by controlling the airflow through the duct of the aerial vehicle; and
controlling at least one parameter of the flight path by modifying the airflow through the duct of the aerial vehicle at least partially, the airflow through the duct of the aerial vehicle modified at least partially by controlling one or more flight control surfaces positioned within the duct, the one or more flight control surfaces moveable between a retracted position within the body and a protruded position within the duct.
2 . The method of claim 1 , wherein the at least one parameter of the flight path corresponds to at least one of a yaw, a pitch, a roll, or a thrust of the aerial vehicle.
3 . The method of claim 1 , wherein modifying the airflow through the duct of the aerial vehicle at least partially includes modifying at least one of a direction, a pressure, or a rate of the airflow.
4 . The method of claim 1 , wherein the one or more flight control surfaces is controlled in response to a communication from an electronic device.
5 . The method of claim 1 , further comprising:
capturing sensor data from an aerial position along the flight path.
6 . The method of claim 5 , further comprising:
moving the aerial vehicle to a second aerial position by controlling the at least one parameter of the flight path; and
capturing second sensor data from the second aerial position.
7 . The method of claim 5 , further comprising:
sending the sensor data to an electronic device.
8 . The method of claim 7 , wherein the sensor data includes at least one of one or more images, a video feed, point cloud data, speed, velocity, attitude, or telemetry data.
9 . The method of claim 1 , wherein the airflow through the duct of the aerial vehicle is generated in response to activation of the aerial vehicle.
10 . The method of claim 9 , wherein the aerial vehicle is activated in response to a sensor being triggered.
11 . The method of claim 10 , wherein the flight path is determined based on a location corresponding to the sensor.
12 . The method of claim 10 , wherein the flight path is determined by tracking a source that triggered the sensor.
13 . The method of claim 1 , wherein a map of a structure is generated based on sensor data captured by the aerial vehicle.
14 . The method of claim 13 , wherein the structure includes at least one of an object, a building, or terrain.
15 . The method of claim 1 , wherein the flight path is predetermined prior to takeoff of the aerial vehicle.
16 . The method of claim 1 , wherein the airflow through the duct of the aerial vehicle is modified in response to one or more decisions made in connection with autonomous navigation of the aerial vehicle using one or more onboard sensors.
17 . The method of claim 16 , wherein the one or more decisions are made by at least one of the aerial vehicle or a computing device separate from the aerial vehicle.
18 . An aerial vehicle comprising:
a body comprising a first end and a second end;
a duct extending from the first end to the second end;
at least one fan generating an airflow through the duct;
one or more flight control surfaces positioned within the duct; and
a flight control system configured to control at least one parameter of a flight path of the aerial vehicle by controlling at least one of the one or more flight control surfaces, the one or more flight control surfaces configured to modify the airflow through the duct at least partially by moving the one or more flight control surfaces between a retracted position within the body and a protruded position within the duct.
19 . The aerial vehicle of claim 18 , wherein the at least one fan is positioned in the duct and the one or more flight control surfaces are positioned at the second end of the duct.
20 . The aerial vehicle of claim 18 , wherein each of the one or more flight control surfaces is configured to move between a retracted position and a protruded position.
21 . The aerial vehicle of claim 18 , wherein each of the one or more flight control surfaces is positionable at an angle of incidence relative to a vertical axis of the duct.
22 . The aerial vehicle of claim 18 , wherein each of the one or more flight control surfaces moves along a path, the path being at least one of fixed, curved, or linear.
23 . The aerial vehicle of claim 18 , wherein the flight control system is in communication with a remote electronic device.
