TECHNICAL FIELD
[002] The present technical disclosure relates generally systems and methods for wirelessly charging of a mobile device, automatically, using an unmanned ground vehicle, a robot with a moving structure, a land mover, or a floor mover with a wheel set having a wireless charging capacity.
BACKGROUND
[003] The usage of mobile devices or smart phones has significantly increased in today’s world. Almost every individual constantly uses mobile devices throughout the day. Due to constant use, a battery unit associated with the mobile device discharges rapidly and that leads to charging of the mobile device more frequently and increases the charging frequency to multiple times a day. Further, a user needs to go to a charging station every time for charging the mobile device which is not feasible and time consuming.
[004] In order to handle such battery drainage and frequent charging problems, the mobile device manufacturers focused on getting larger and bigger capacity battery units for mobile devices, which in turn led to mobile devices being thicker and bulkier. Often the larger battery capacity requires a larger device space as the size is bigger which also adds up to overall weight and production cost of the mobile devices significantly. Another focus for the manufacturers was to reduce the size of the battery unit for achieving a slimmer structure and less thickness, which in turn leads to the battery unit being of a lesser capacity.
[005] The constant usage of the mobile device throughout the day makes it impossible to charge the mobile device rapidly. Also, the remaining usable battery unit and the charging status need to be checked frequently so that the mobile device can be plugged in to the power for charging purposes. The need to charge the mobile device for optimal functioning of the mobile device and for use in any pre-scheduled meetings cannot be achieved as there is no battery capacity left in the mobile device to be operational. The user may also sometimes forget to charge the mobile device and may also not notice the remaining battery percentage for functioning of the mobile device, which makes it a hassle. The need to go to a charging station personally for charging the mobile device and also waiting for the same till it is fully charged is not optimal for the user or any individual. These limitations significantly reduce the work efficiency of the user with a disturbance in the work schedule too.
[006] Therefore, there is a need of a system and method which solves the above-mentioned problems and can provide an efficient system and method for auto wirelessly charging of the mobile device.

Although a system for auto wireless charging of a mobile device and method thereof, similar, or equivalent to those described herein can be used in the practice or testing of embodiments of the present disclosure, the exemplary, a system for auto wireless charging of a mobile device and method thereof is now described.
[0020] Various modifications to the embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments. For example, although the present disclosure will be described in the context of a system for auto wireless charging of a mobile device and method thereof, one of ordinary skill in the art will readily recognize a system for auto wireless charging of a mobile device and method thereof can be utilized in any situation. Thus, the present disclosure is not intended to be limited to the embodiments illustrated but is to be accorded the widest scope consistent with the principles and features described herein.
[0021] In an exemplary embodiment, a mobile device which needs to be charged and a land mover are provided. The mobile device has different units and modules such as a sensor unit, a control unit, a determination module, a selection module, an obstacle identifier, a path identifier, a communication module, a driving management module, and a computation module. In an embodiment, a battery unit of the mobile device to be charged is constantly monitored by the sensor unit. A land mover is located at a charging station/dock in a closed area. In an ideal time, when the land mover is not in an active mode, the land mover docked on the charging station and keeps the battery recharged.
[0022] In another exemplary embodiment, if the battery percentage of the mobile device is equal to or less than a predetermined threshold battery percentage, then the sensor unit sends an instruction to the control unit regarding a pre-configured level of battery status. As per the battery status, the control unit scans the available land movers based on all the charging docks /stations installed in the premises. Based on the information of the available charging device as well as the location of the mobile device, the control unit determines the closest available land mover and also the location of the mobile device. Upon determination of the availability of the land mover and the charging dock/station, the control unit sends an instruction to the driving management module of the mobile device and the nearest available land mover.
[0023] In another exemplary embodiment, upon receiving the instruction, the driving management module activates the moving mechanism such as moving wheels or umbrella to reach to the land mover at a set point, if required for connecting with the mobile device, and further enabling the charging process. Alternatively, the land mover locates the mobile device and reaches out to its location for most parts without the need of the mobile device to be travelled. The closest land mover also responds to the request sent by the control unit and sends back a signal indicating the acceptance of the request. The land mover reaches the mobile device at a point nearby and locks itself with the mobile device for wireless charging without navigating to the charging station. The land mover with the help of the control unit having a camera vision and obstacle avoiding features reaches the location of the mobile device and charges the mobile device wirelessly. Upon validation, the mobile device using an alignment process, locks itself with the charging station and after a single tap, the wireless charging capabilities of the land mover is activated, and the mobile device starts charging the battery unit.
[0024] In another exemplary embodiment, a system and method for wireless charging of a mobile device by transporting the mobile device to a nearby charging dock/station is provided. It is important to note that the transportation of the mobile device can be a transportation through the land mover such as through an unmanned ground vehicle, a robot with a moving structure, or a floor mover with a wheel set. The transportation of the mobile device can be activated when the transportation carrier indicates that it does not have any charging capabilities because of the discharge status of the battery unit installed in such transportation carriers. The mobile device and the land mover may have a control unit, a sensor unit, a driving management module, and other units/modules, which enable the mobile device to take appropriate decision with respect to wireless charging of the mobile device. The sensor unit constantly monitors the battery unit of the mobile device. If the battery percentage is equal to or less than a threshold battery percentage value, then the sensor unit sends the instruction to the control unit regarding a pre-configured level of the battery status. As per the battery status, the control unit sends one or more signals to nearby land movers available in a premises as well as charging docks /stations installed in the same premises. Based on the information of all the available charging docks /stations as well as the location of the mobile device, the control unit determines the closest available land mover for transportation and the location of the charging dock /station. Upon determination of the charging station, the control unit sends the instructions /signals to the one or more land movers. Upon receiving the instructions /signals, the closest land movers respond to the request and send back a signal indicating the acceptance of the request. The identified land mover reaches the location of the mobile device and picks up the mobile device to be charged and navigates to the nearest charging dock as identified and communicated by the control unit of the mobile device. Once the land mover along with the mobile device reaches the identified charging station, the control unit of the mobile device validates the charging station which has a wireless charging property. Upon validation, the land mover places the mobile device safely on the charging station, the wireless charging capabilities of the charging station is thereby activated, and the mobile device starts charging the battery unit.
[0025] In another exemplary embodiment, as soon as battery charging process completed, the identified land mover may receive another signal request from the mobile device being charged on the identified charging dock/ station. Upon validating the signal request, the land mover picks up the mobile device from the charging station and takes it to the original location from where the mobile device was located prior to the charging process.
[0026] Some of the objects of the present technical subject matter, which at least one embodiment herein satisfies, are as follows.

[0073] The system (100) further identifies the driving mechanism and available land movers (120) for picking the mobile device (101) to the charging station (122). In an embodiment, the driving mechanism includes a land charging mechanism. In one embodiment, the driving mechanism may be of a pre-defined dimension.
[0074] In an embodiment, the system (100) computes the time required to travel the mobile device (101) to the charging station (122) by using the identified land mover (120) for the selected paths. In an embodiment, the system (100) computes the time for the selected paths taken by the land mover (120). In another embodiment, the system (100) computes the time for the selected paths taken by the land mover (120). In another embodiment, the system (100) computes the time for one or more selected paths taken by the land mover (120). The system (100) then checks the computed time of the land mover (120) for each path. The system (100) then selects a specific path which has less travel time. Thereafter, the system (100) actuates the identified moving mechanism and sends the signal to the selected land mover (120) to pick up the mobile device (102) and approaches for further charging. Upon receiving signal, the selected land mover (120) then picks up the mobile device (101) and approaches the charging station (122) for charging the mobile device (101). After charging, when the percentage level of the mobile device (101) reaches the pre-defined percentage level, the charging station (122) sends the signal to the selected land mover (120) to take the mobile device (101). The selected land mover (120) again picks up the mobile device (101) and places the mobile device (101) to a location where the land mover (120) picked up for charging the mobile device (101).

At a step (510), the control unit (104) checks if manual press start process of charging is initiated. If the process is not initiated, the process stops at a step (522). If the process is initiated, the system (100) checks the land mover (118) to pick up the mobile device (101), as shown at a step (516). In an embodiment, the land mover (118) is a picker. At a step (518), the land mover (118) picks up the mobile device (101). At a step (520), the land mover (108) lifts the mobile device (101) and navigates to the nearest charging station (122).
