Abstract

Described are systems and methods, including computer program products for controlling an unmanned vehicle. A user controls one or more unmanned vehicles with a smart phone. The smart phone receives video stream from the unmanned vehicles, and the smart phone displays the controls from the unmanned vehicle over the video. The smart phone and the unmanned vehicle communicate wirelessly.

Claims

1. A computerized method for controlling an unmanned vehicle, comprising:

receiving, by a smart phone, a request to control the unmanned vehicle;

establishing, by the smart phone, wireless communication between the smart phone and the unmanned vehicle;

receiving, by the smart phone, a video stream generated by the unmanned vehicle;

displaying the video stream and vehicle controls on a touch-sensitive display screen within the smart phone; and

manipulating the vehicle controls to direct the unmanned vehicle.

2. The computerized method of claim 1, further comprising:

receiving, by the smart phone, information to direct the unmanned vehicle;

converting, by the smart phone, the information into a protocol recognizable by the unmanned vehicle; and

transmitting, by the smart phone, the converted information to the unmanned vehicle.

3. The computerized method of claim 1, further comprising establishing communication with the unmanned vehicle via a wireless local area network.

4. The computerized method of claim 1, wherein establishing communication further comprises:

transmitting, by the smart phone, an initiation request via a cable to a rf transmitter;

transmitting, by the rf transmitter, the initiation request to the unmanned vehicle;

receiving, by the rf transmitter, a message from the unmanned vehicle; and

transmitting, by the rf transmitter, the message from the unmanned vehicle to the smart phone via the cable to the smart phone.

5. The computerized method of claim 1, further comprising providing a joystick for governing the acceleration, deceleration, and direction of travel of the unmanned vehicle.

6. The computerized method of claim 5, further comprising providing a controller to govern movement of one or more robot arms of the unmanned ground vehicle.

7. The computerized method of claim 1, further comprising providing a control to set a maximum speed of the unmanned vehicle.

8. The computerized method of claim 1, further comprising providing a control to store a frame of the video stream as a picture on the smart phone.

9. The computerized method of claim 1, further comprising providing a control to command one or more cameras on the unmanned vehicle to zoom in or out.

10. The computerized method of claim 1, further comprising providing one or more controls to command the unmanned vehicle to one or more predetermined poses.

11. The computerized method of claim 1, further comprising:

receiving, by the smart phone, information of objects within a distance of the unmanned vehicle; and

displaying, on the smart phone, the unmanned vehicle with the objects positioned relative to the unmanned vehicle based the information.

12. The computerized method of claim 1, further comprising displaying the controls and a geographic map on the display screen within the smart phone.

13. The computerized method of claim 1, further comprising displaying one or more arrows, the video stream, and the controls on the display within the smart phone, wherein the one or more arrows indicate a heading for the unmanned vehicle such that the unmanned vehicle can reach a specified location.

14. A computerized method for controlling an unmanned vehicle, comprising:

receiving, by a smart phone, a request to control the unmanned vehicle;

establishing, by the smart phone, wireless communication between the smart phone and the unmanned vehicle;

receiving, by operator manipulation of vehicle controls disposed on a touch-sensitive display screen within the smart phone, information to direct the unmanned vehicle in a direction;

processing, by the smart phone, the information to reduce operator error, if any, within the information; and

transmitting, by the smart phone, the processed information to the unmanned vehicle.

15. The computerized method of claim 14, further comprising receiving information to rotate the unmanned vehicle.

16. The computerized method of claim 14, further comprising receiving information to move a robotic arm on the vehicle.

17. A computerized method for controlling an unmanned vehicle, comprising:

receiving, by a smart phone, a request to control the unmanned vehicle;

establishing, by the smart phone, wireless communication between the smart phone and the unmanned vehicle;

receiving, by the smart phone, a video stream generated by the unmanned vehicle;

displaying the video stream and vehicle controls on a touch-sensitive display screen within the smart phone;

receiving, by operator manipulation of the vehicle controls, information to direct the unmanned vehicle in a direction;

processing, by the smart phone, the information to reduce operator error, if any, within the information; and

transmitting, by the smart phone, the processed information to the unmanned vehicle.

18. A computerized method for controlling a plurality of unmanned vehicles, comprising:

receiving, by a smart phone, a request to control the unmanned vehicles;

establishing, by the smart phone, wireless communication between the smart phone and each of the unmanned vehicles;

receiving, by the smart phone, a video stream from each of the unmanned vehicles;

selecting, by the smart phone, one of the plurality of unmanned vehicles;

displaying the video stream and vehicle controls of the selected vehicle on a display screen within the smart phone;

manipulating the displayed vehicle controls to direct the selected unmanned vehicle.

19. The computerized method of claim 18, wherein establishing a wireless communication further comprises transmitting, by the smart phone, a signal to each of the plurality of unmanned vehicles, such that the signal changes to a protocol of the particular unmanned vehicle the signal is transmitting to.

20. The computerized method of claim 18, further comprising displaying controls that correspond to the particular unmanned vehicle from which the video stream is received.

21. The computerized method of claim 18, further comprising toggling between displaying the video stream and controls of each of the plurality of unmanned vehicles based on operator input.

22. The computerized method of claim 18, further comprises:

selecting, by the smart phone, two of the plurality of the unmanned vehicles; and

displaying the video stream and controls of the two selected vehicles on a display screen within the smart phone; and

manipulating the displayed controls to direct the two selected unmanned vehicles.
