Abstract

A rotor-based remote flying vehicle platform comprises a central frame with a control center that is configured to control motors mounted to the vehicle platform. A first arm is connected to the central frame and extends outward. A first motor is mounted to the first arm. The first motor is in communication with the control center. Further, a first tilt actuator is configured to tilt the first motor within a first plane.

Claims (46)

1. A rotor-based remote flying vehicle platform comprising:

a central frame with a control center that is configured to control motors mounted to the vehicle platform, wherein controlling the motors mounted to the vehicle platform comprises:

detecting when a current tilt of the rotor-based remote flying vehicle platform has reached a pre-determined threshold, and

in response to detecting that the current tilt of the rotor-based remote flying vehicle platform has reached the pre-determined threshold, automatically causing a first tilt actuator of the rotor-based remote flying vehicle to tilt a first motor of the rotor-based remote flying vehicle platform to reduce the current tilt of the rotor-based remote flying vehicle platform;

a first arm that is connected to the central frame and extends outward;

the first motor mounted to the first arm, wherein the first motor is in communication with the control center; and

the first tilt actuator configured to tilt the first motor within a first plane.

2. The rotor-based remote flying vehicle platform as recited in claim 1 , further comprising:

multiple arms connected to the central frame and extending outward;

multiple motors mounted to the respective arms, wherein the multiple motors are in communication with the control center; and

multiple tilt actuators configured to tilt the respective motors within a respective plane.

3. The rotor-based remote flying vehicle platform as recited in claim 2 , wherein the first tilt actuator and the multiple tilt actuators are configured to tilt the first motor and the respective motors within multiple respective planes.

4. The rotor-based remote flying vehicle platform as recited in claim 1 , wherein the first tilt actuator comprises a first motor mount.

5. The rotor-based remote flying vehicle platform as recited in claim 4 , wherein the first motor mount connects the first motor to the first arm.

6. The rotor-based remote flying vehicle platform as recited in claim 1 , wherein the first tilt actuator connects the first arm to the central frame.

7. The rotor-based remote flying vehicle platform as recited in claim 1 , wherein the first tilt actuator adjusts based upon the current operating characteristics of the rotor-based remote flying vehicle platform.

8. The rotor-based remote flying vehicle platform as recited in claim 1 , wherein the first tilt actuator comprises a slip ring.

9. The rotor-based remote flying vehicle platform as recited in claim 8 , wherein the first tilt actuator is configured to rotate the first motor 360°.

10. A computer-embodiment method for adjusting the direction of thrust for motors on a rotor-based remote flying vehicle platform, the method comprising:

receiving a first command to change a current trajectory of the rotor-based remote flying vehicle platform;

in response to receiving the first command, changing the current trajectory of the rotor-based remote flying vehicle platform;

upon changing the current trajectory, detecting that a current tilt of the rotor-based remote flying vehicle platform has reached a pre-determined threshold;

in response to dectecting that the current tilt of the rotor-based remote flying vehicle platform has reached the pre-determined threshold, automatically reducing the current tilt of the rotor-based remote flying vehicle platform, wherein reducing the current tilt of the rotor-based remote flying vehicle platform comprises at least the following:

identifying a first current operating condition of a first motor of the rotor-based remote flying vehicle platform, wherein the first current operating condition comprises an indication of a current tilt associated with the first motor;

calculating, based upon the first current operating conditions and the first command, a first tilt command for the first motor, wherein the first tilt command comprises instructions for causing a first tilt actuator to apply a first specific tilt to the first motor; and

applying, with the first tilt actuator, the first specific tilt to the first motor.

11. The method as recited in claim 10 , further comprising:

identifying a second current operating condition of a second motor of the rotor-based remote flying vehicle platform, wherein the second current operating condition comprises an indication of a current tilt associated with the second motor;

calculating, based upon the second current operating conditions and the first command, a second tilt command for the second motor, wherein the second tilt command comprises instructions for causing a second tilt actuator to apply a second specific tilt to the second motor; and

applying, with the second tilt actuator, the second specific tilt to the second motor.

12. The method as recited in claim 11 , further comprising:

applying, with a third tilt actuator, a third specific tilt to a third motor; and

applying, with a fourth tilt actuator, a fourth specific tilt to a fourth motor.

13. The method as recited in claim 10 , wherein the first motor is positioned on a distal end of an arm with respect to a vehicle body.

14. The method as recited in claim 13 , wherein the first actuator is positioned between the first motor and the vehicle body.

15. The method as recited in claim 10 , wherein the first tilt command comprises an instruction for causing the first tilt actuator to rotate 180°.

16. The method as recited in claim 15 , wherein the first tilt actuator comprises a slip ring.

17. The method as recited in claim 15 , wherein the first tilt actuator comprises at least two planes of movement.

18. The method as recited in claim 10 , wherein the first command comprises a command to configure the rotor-based remote flying vehicle into a high-speed configuration, wherein the high-speed configuration comprises tilting two adjacent motors to a common tilt.

19. The method as recited in claim 10 , further comprising:

automatically adjusting, within a flight control system, a rotational speed of at least one other motor to compensate for the first specific tilt of the first motor.

20. A rotor-based remote flying vehicle platform comprising:

a central frame with a control center that is configured to control motors mounted to the vehicle platform, including detecting when a current tilt of the rotor-based remote flying vehicle platform has reached a pre-determined threshold and in response to detecting that the current tilt of the rotor-based remote flying vehicle platform has reached the pre-determined threshold, automatically causing at least one actuator of the rotor-based remote flying vehicle to tilt a corresponding motor of the rotor-based remote flying vehicle platform to reduce the current tilt of the rotor-based remote flying vehicle platform;

at least four arms that are connected to the central frame and extends outward in different directions;

at least four motors, each motor attached to one of the at least four arms, wherein each motor is in communication with the control center; and

at least four actuators, each actuator configured to tilt one of the at least four motors, wherein each actuator comprises at least two planes of movement.
