Abstract

Aspects of the present disclosure relate to self-driving luggage systems, devices, and components thereof, having multiple following modes. In one implementation, a self-driving system includes a piece of luggage. The piece of luggage includes one or more motorized wheels and an onboard ultra-wideband device. The onboard ultra-wideband device includes a control unit and one or more transceivers. The piece of luggage also includes one or more laser emitters configured to shoot light towards a target. The piece of luggage also includes one or more proximity cameras configured to take one or more images of the target, and the one or more images include light reflected off of the target. Each of the one or more proximity cameras includes an optical filter. The self-driving system also includes a central processing unit. The central processing unit is configured to switch between a vision following mode and a radio following mode.

Claims (61)

an onboard radio wave based device having a control unit and one or more transceivers, and

one or more cameras configured to take one or more images of a target;

a central processing unit configured to:

switch between a vision following mode and a radio wave following mode,

determine a distance to the target, and

generate instructions regarding a position of the piece of luggage;

wherein in the vision following mode the central processing unit is configured to receive from the one or more cameras one or more images of the target; and

wherein in the radio wave following mode the central processing unit is configured to receive information from the onboard radio wave based device.

2. The self-driving system of claim 1 , wherein the control unit of the onboard radio wave based device and the central processing unit are integrated into a single processing unit.

3. The self-driving system of claim 1 , further comprising a wheel control module and one or more laser emitters configured to shoot light towards the target, wherein the onboard radio wave based device comprises an ultra-wideband device, wherein in the vision following mode the central processing unit determines the distance to the target using a height at which the light is reflected off of the target, and the wheel control module receives the instructions generated by the central processing unit regarding the position of the piece of luggage, and in response to the received instructions the wheel control module moves the piece of luggage in a given direction.

4. The self-driving system of claim 1 , wherein the central processing unit is configured to automatically switch from the vision following mode to the radio wave following mode upon detecting an obstructed image.

5. The self-driving system of claim 4 , wherein the obstructed image is obstructed by an environmental condition.

6. The self-driving system of claim 1 , wherein the central processing unit is configured to automatically switch from the radio wave following mode to the vision following mode upon detecting an unobstructed image.

7. The self-driving system of claim 1 , wherein the central processing unit is configured to automatically switch from the vision following mode to the radio wave following mode upon moving from an indoor environment to an outdoor environment.

8. The self-driving system of claim 1 , wherein the central processing unit is configured to automatically switch from the radio wave following mode to the vision following mode upon moving from an outdoor environment to an indoor environment.

9. The self-driving system of claim 1 , further comprising:

a mobile radio wave based device with a transmitter configured to transmit a signal to the one or more transceivers of the onboard radio wave based device;

a wheel control module; and

wherein in the radio wave following mode the central processing unit determines the distance to the target using the signal transmitted from the transmitter to the one or more transceivers, and the wheel control module receives the instructions generated by the central processing unit regarding the position of the piece of luggage, and in response to the received instructions the wheel control module moves the piece of luggage in a given direction.

10. The self-driving system of claim 9 , wherein the mobile radio wave based device comprises a belt clip.

11. The self-driving system of claim 1 , wherein each of the one or more cameras includes a wide-angle lens.

12. A self-driving system, comprising:

a piece of luggage, the piece of luggage comprising:

one or more motorized wheels,

an onboard radio wave based device having a control unit and one or more transceivers, and

one or more cameras configured to take one or more images of a target;

a mobile radio wave based device; and

a central processing unit configured to:

switch between a vision following mode and a radio wave following mode based on a change in one or more environmental conditions,

determine a distance to the target, and

generate instructions regarding a position of the piece of luggage;

wherein in the vision following mode the central processing unit is configured to receive from the one or more cameras one or more images of the target; and

wherein in the radio wave following mode the central processing unit is configured to receive information from the onboard radio wave based device.

13. The self-driving system of claim 12 , wherein the mobile radio wave based device comprises a battery and a charging outlet to recharge the battery.

14. The self-driving system of claim 12 , wherein the mobile radio wave based device comprises a status light, and the status light is configured to indicate a power status of the mobile radio wave based device.

15. The self-driving system of claim 12 , wherein the mobile radio wave based device comprises a housing, a transmitter configured to transmit a signal to the one or more transceivers of the onboard radio wave based device, a battery, and a mounting clip.

16. The self-driving system of claim 15 , wherein the housing comprises one or more protrusions that protrude from the housing, and the mounting clip comprises a belt clip that is pivotably mounted to the one or more protrusions.

17. The self-driving system of claim 16 , wherein the central processing unit is configured to automatically switch from the vision following mode to the radio wave following mode upon detecting an obstructed image due to the change in the one or more environmental conditions.

18. A self-driving system, comprising:

a piece of luggage, the piece of luggage comprising:

one or more motorized wheels,

an onboard radio wave based device having a control unit and one or more transceivers, and

one or more cameras configured to take one or more images of a target;

a status indicator;

a central processing unit configured to:

switch between a vision following mode and a radio wave following mode,

determine a distance to the target, and

generate instructions regarding a status of the piece of luggage;

wherein in the vision following mode the central processing unit is configured to receive from the one or more cameras one or more images of the target, and the instructions generated by the central processing unit instruct the status indicator to emit a first light indicator; and

wherein in the radio wave following mode the central processing unit is configured to receive information from the onboard radio wave based device, and the instructions generated by the central processing unit instruct the status indicator to emit a second light indicator that is different than the first light indicator.
