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.
