Abstract

A mobile device moving in a specific area including a driving unit, an environment sensing unit, a control unit and a transmittal unit is disclosed. The driving unit moves according to a first driving signal. The environment sensing unit detects an outline of the specific area to generate detection information. The control unit processes the detection information to generate first map information and position information. The transmittal unit transmits the first map information to an electronic device. The electronic device generates second map information according to the first map information, and the control unit generates the first driving signal according to the first map information, the second map information and the position information.

Claims

1. A mobile device moving in a specific area, comprising:

a driving unit moving according to a first driving signal;

an environment sensing unit detecting an outline of the specific area to generate detection information;

a control unit processing the detection information to generate first map information and position information; and

a transmittal unit transmitting the first map information to an electronic device,

wherein the electronic device generates second map information according to the first map information, and the control unit generates the first driving signal according to the first map information, the second map information and the position information.

2. The mobile device as claimed in claim 1, wherein the environment sensing unit comprises:

a first sensor detecting a distance between the mobile device and an object; and

a second sensor detecting a moving length and a moving direction of the driving unit.

3. The mobile device as claimed in claim 2, wherein the first sensor is a laser sensor and the second sensor is an odometer.

4. The mobile device as claimed in claim 1, wherein the control unit processes the detection information according to simultaneous localization and mapping (SLAM) technology.

5. The mobile device as claimed in claim 1, wherein the environment sensing unit generates the detection information according to an unclean level of the specific area, the control unit marks an enhancement sign in the first map information according to the detection information, wherein the enhancement sign corresponds to an unclean area of the specific area.

6. The mobile device as claimed in claim 5, further comprising:

a cleaning unit controlled by the control unit to operate in a first mode or in a second mode, wherein when the mobile device moves into the unclean area, the cleaning unit operates in the first mode and has a first cleaning efficiency, and when the mobile device leaves the unclean area, the cleaning unit operates in the second mode and has a second cleaning efficiency, and the first cleaning efficiency is higher than the second cleaning efficiency.

7. The mobile device as claimed in claim 6, wherein when the unclean level is less than a pre-determined level, the control unit removes the enhancement sign from the first map information, and when the mobile device moves to the unclean area, the control unit controls the cleaning unit to operate in the second mode.

8. The mobile device as claimed in claim 1, wherein the electronic device marks an enhancement sign in the first map information to generate the second map information, and wherein the enhancement sign corresponds to an unclean area of the specific area.

9. The mobile device as claimed in claim 8, wherein the control unit generates a second driving signal to a cleaning unit according to the second map information, whereby the cleaning unit enhances a cleaning efficiency for the unclean area.

10. The mobile device as claimed in claim 1, wherein the electronic device is separated from the mobile device.

11. The mobile device as claimed in claim 1 , wherein the electronic device is integrated with the mobile device.

12. The mobile device as claimed in claim 11, wherein the electronic device is a display panel to display the first map information.

13. The mobile device as claimed in claim 12, wherein the display panel provides the second map information according to an external control command.

14. The mobile device as claimed in claim 1, wherein the control unit determines a position of the mobile device according to the first map information and plans a traveling path of the mobile device according to the second map information.
