Abstract

The robot in this invention can detect the fading or loss of wireless network signal as an indication of being removed from its working area and enter into alert mode. The purpose of robot entering into alert mode is to deter physical theft, e.g., by sounding an alarm, to protect confidential data loss, and to render the robot useless to an unauthorized person, reducing the incentives for theft. A number of techniques are employed in this invention: confidential data stored on the robot is encrypted; administrator is required to log in the robot to enable robot operations; robot is to detect abnormal conditions such as fading of wireless network signal, sudden loss of wireless network signal, loss of connectivity to management server, and physical disconnection of any computing part from itself; robot is to resume normal operations without administrator intervention when abnormal condition is rectified; an Internet management server instructs the robot to delete stored data when the robot fails to authenticate itself; and place the reset button of a computing part of the robot such that the reset button is only accessible when the computing part is physically disconnected from the robot.

Claims

1. A method for preventing theft of a robot connected to a management server via a wireless network, the method comprising the steps, executed in a processor of the robot, of:

encrypting confidential data stored on said robot;

requiring successful login to enable normal operations of said robot; and

entering alert mode when detecting abnormal conditions.

2. The method as in claim 1, wherein said robot receive one or more wireless network signals from one or more basestations in said wireless network.

3. The method as in claim 2, wherein said confidential data comprise access passwords of said one or more basestations.

4. The method as in claim 2, wherein said abnormal conditions comprise fading of all of said one or more wireless network signals to below a threshold.

5. The method as in claim 2, wherein said abnormal conditions comprise a sudden loss of all of said one or more wireless network signals.

6. The method as in claim 1, wherein said abnormal conditions comprise loss of network connectivity to said management server.

7. The method as in claim 1, wherein said robot comprises a plurality of computing parts having communicative connectivity to each other.

8. The method as in claim 7, wherein said abnormal conditions comprise a loss of said communicative connectivity to one of said plurality of computing parts from said robot.

9. The method as in claim 7, wherein a reset button of said robot is located on said robot where said reset button is only physically accessible when a computing part, of said plurality of computing parts, is physically disconnected from said robot.

10. The method as in claim 1, wherein said entering alert mode comprises disabling said normal operations.

11. The method as in claim 1, wherein said entering alert mode comprises sounding an alarm of said robot.

12. The method as in claim 1, wherein said entering alert mode comprises sending a notification to an administrator of said robot.

13. The method as in claim 1, wherein said entering alert mode comprises requiring successful login before resuming said normal operations.

14. The method as in claim 1, further comprising the step of resuming said normal operations automatically when said abnormal conditions that caused said robot to enter said alert mode are rectified.

15. The method as in claim 1, further comprising the step of requiring successful login to resume said normal operations when having entered in said alert mode.

16. The method as in claim 1, further comprising the step of requiring successful login to disable said normal operations when having enabled said normal operations.

17. The method as in claim 1, wherein said robot deletes said confidential data when failing a sanity check of a specified server on Internet.

18. The method as in claim 17, wherein said specified server on Internet records an IP address of said robot and network routes to reach said robot.

19. A robot comprising:

a plurality of computing parts having communicative connectivity to each other, wherein one computing part, of said plurality of computing parts, disables normal operations of said robot when detecting a loss of said communicative connectivity to another computing part, of said plurality of computing parts; and

a reset button, located on said robot, wherein said reset button is only physically accessible when said one computing part, of said plurality of computing parts, is physically disconnected from said another computing part, of said plurality of computing parts.
