Abstract

A method of analyzing a propeller status of a wireless aerial robot can include measuring status information related to the propeller status by a sensor of a propeller; determining whether an operation of the propeller is abnormal based on the status information; transmitting the status information and operation information regarding whether an operation of the propeller is abnormal to a control unit using short range wireless communication; and analyzing, by the control unit, a flight status of the wireless aerial robot based on the status information and the operation information regarding whether the operation of the propeller is abnormal.

First claim

What is claimed is:

1. A method of analyzing a propeller status of a wireless aerial robot, the method comprising:
measuring status information related to the propeller status by a sensor of a propeller;
determining whether an operation of the propeller is abnormal based on the status information to generate operation information;
transmitting the status information and the operation information regarding whether an operation of the propeller is abnormal to a control unit using short range wireless communication;
analyzing, by the control unit, a flight status of the wireless aerial robot based on the status information and the operation information regarding whether the operation of the propeller is abnormal; and
wirelessly charging a battery connected to the sensor by passing a wireless charging receiving unit disposed in a blade of the propeller over a wireless charging transmitting coil disposed in a drone arm of the wireless aerial robot.

2. The method of claim 1 , wherein the control unit is disposed inside a propeller blade of the propeller.

3. The method of claim 1 , wherein the sensor is disposed inside a propeller blade of the propeller.

4. The method of claim 1 , wherein the sensor is an acceleration sensor.

5. The method of claim 1 , wherein the status information is measured based on a parameter corresponding to at least one of torque, lift or a vibration of the propeller.

6. The method of claim 5 , wherein the determining whether the operation of the propeller is abnormal includes:
comparing the parameter with a minimum value and a maximum value; and
determining that the propeller is in an erroneous operation state when the parameter is less than the minimum value or greater than the maximum value.

7. The method of claim 6 , wherein the propeller is determined to be in a normal operation state when the parameter is greater than the minimum value and less than the maximum value.

8. The method of claim 6 , further comprising:
in response to determining that the propeller is in the erroneous operation state, transmitting the flight status to a base station using wireless communication;
receiving instruction information instructing a specific operation from the base station based on the flight status; and
performing the specific operation.

9. The method of claim 8 , wherein the specific operation is a landing operation of the wireless aerial robot.

10. A wireless aerial robot, comprising:
a main body;
a propeller for flying the wireless aerial robot; and
a drone arm for connecting the propeller with the main body, wherein the propeller includes:
a sensor configured to measure status information related to a propeller status of the propeller, a micro control unit (MCU) configured to determine whether an operation of the propeller is abnormal based on the status information to generate operation information regarding whether an operation of the propeller is abnormal, and
a short range wireless communication unit configured to transmit the status information and the operation information to a control unit using short range wireless communication,
a battery for supplying power to the MCU and the sensor,
a wireless charging receiving unit for charging the battery by a rotation of the propeller, and
wherein the control unit is disposed in the main body of the wireless aerial robot, and the control unit is configured to analyze a flight status of the wireless aerial robot based on the status information and the operation information regarding whether the operation of the propeller is abnormal.

11. The wireless aerial robot of claim 10 , wherein the MCU and the sensor are disposed on a first side of the propeller, and
wherein the battery and the wireless charging receiving unit are disposed at a second side of the propeller, the second side of the propeller being opposite to the first side of the propeller.

12. The wireless aerial robot of claim 10 , wherein the drone arm includes a wireless charging transmission unit for generating power through the wireless charging receiving unit.

13. The wireless aerial robot of claim 10 , wherein the battery is a thin film battery.

14. The wireless aerial robot of claim 10 , wherein the control unit includes an electronic stability control (ESC) and a flight controller (FC).

15. The wireless aerial robot of claim 10 , wherein the status information is measured based on a parameter corresponding to at least one of torque, lift or a vibration of the propeller.

16. The wireless aerial robot of claim 15 , wherein the MCU is further configured to:
compare the parameter with a minimum value and a maximum value; and
determine that the propeller is in an erroneous operation state when the parameter is less than the minimum value or greater than the maximum value.

17. The wireless aerial robot of claim 15 , wherein the control unit is further configured to:
transmit the flight status to a base station using wireless communication when the propeller is in an erroneous operation state,
receive instruction information instructing a specific operation from the base station based on the flight status, and
perform the specific operation.

18. The wireless aerial robot of claim 17 , wherein the specific operation is a landing operation of the wireless aerial robot.
