Abstract

Embodiments of the present disclosure include automated guided vehicles (AGVs) having a broadcasting system. In one embodiment, the self-driving system includes a body having one or more motorized wheels, a console coupled in an upright position to an end of the body, and a broadcasting system disposed at the console and is operable to send a notification to one or more mobile devices, wherein the broadcasting system uses a first type of positioning system and the one or more mobile devices use a second type of positioning system different from the first type of positioning system.

First claim

The invention claimed is:

1. A self-driving system, comprising:
a body having one or more motorized wheels;
a console coupled in an upright position to an end of the body; and
a broadcasting system disposed at the console and is operable to send a notification to be received by one or more mobile devices by means of broadcasting the notification, wherein the notification has a broadcasting range, and the broadcasting system is configured to increase the broadcasting range if one or more mobile devices are not responsive for more than a pre-determined duration of time,
wherein the broadcasting system uses a first type of positioning system and the one or more mobile devices use a second type of positioning system different from the first type of positioning system, wherein the first type of positioning system has higher accuracy than the second type of positioning system, the first type of positioning system is a high accuracy positioning system comprising a simultaneous localization and mapping (SLAM) or visual SLAM (VSLAM) based system, an inertial measurement system, markers, or any combination thereof, and the second type of positioning system is a low accuracy positioning system comprising a WiFi/LiFi based positioning system, a wireless communication beacon, a magnetic positioning system, a system using dead reckoning technology, or any combination thereof.

2. The system of claim 1 , further comprising:
an actuator operable to adjust a height of the body; and
an inventory holder removably disposed on the body, the inventory holder comprising wheels and an inventory supporting surface.

3. The system of claim 1 , wherein the broadcasting system is configured to send the notification to multiple mobile devices using a Peer-to-Peer communication.

4. The system of claim 1 , wherein the one or more mobile devices are associated with a designated area or associated with recipients related to the designated area.

5. The system of claim 1 , wherein the broadcasting system is configured to adjust the broadcasting range depending on an importance level of the notification.

6. The system of claim 5 , wherein the broadcasting range has a radial distance ranging from 20 meters to 300 meters.

7. A method of operating a self-driving system, comprising:
operating the self-driving system in a self-driving mode to a designated area of a facility;
estimating a distance between the self-driving system and one or more mobile devices located within the facility using a strength of a wireless signal from a first type of positioning system used by the self-driving system and a strength of a wireless signal from a second type of positioning system used by the one or more mobile devices, wherein the first type of positioning system has higher accuracy than the second type of positioning system;
broadcasting from the self-driving system a notification to be received by one or more mobile devices that has the estimated distance falling within a pre-determined broadcasting range of the self-driving system; and
terminating broadcasting of the notification when one or more mobile devices respond to the notification sent from the self-driving system; and
increasing a coverage of the pre-determined broadcasting range if one or more mobile devices is not responding over a pre-determined duration of time or an importance level of the notification is changed.

8. The method of claim 7 , wherein the first type of positioning system is a high accuracy positioning system comprising a simultaneous localization and mapping (SLAM) or visual SLAM (VSLAM) based system, an inertial measurement system, markers, or any combination thereof, and the second type of positioning system is a low accuracy positioning system comprising a WiFi/LiFi based positioning system, a wireless communication beacon, a magnetic positioning system, a system using dead reckoning technology, or any combination thereof.

9. A self-driving system, comprising:
a body having one or more motorized wheels;
a console coupled in an upright position to a front end of the body; and
a broadcasting system disposed at the console and is operable to send a notification to be received by one or more mobile devices by means of broadcasting the notification via a wireless communication, wherein the notification has a broadcasting range, and the broadcasting system is configured to increase the broadcasting range if one or more mobile devices are not responsive for more than a pre-determined duration of time,
wherein the broadcasting system uses a first type of positioning system and the one or more mobile devices use a second type of positioning system different from the first type of positioning system, and wherein the first type of positioning system has higher accuracy than the second type of positioning system.

10. The system of claim 9 , further comprising:
one or more proximity sensors disposed at corners of the body.

11. The system of claim 10 , further comprising:
a first LiDAR sensor disposed at a first cutout extending across a front side of the body; and
a second LiDAR sensor disposed at a second cutout extending across a rear side of the body.

12. The system of claim 11 , wherein the first cutout expands radially and outwardly from a center of the front side to opposing sides of the body, and the second cutout expands radially and outwardly from a center of the rear side to the opposing sides of the body.
