Surveillance prevention by mobile robot
A mobile robot is configured for operation in a commercial or industrial setting, such as an office building or retail store. The robot can patrol one or more routes within a building, and can detect violations of security policies by objects, building infrastructure and security systems, or individuals. In response to the detected violations, the robot can perform one or more security operations. The robot can include a removable fabric panel, enabling sensors within the robot body to capture signals that propagate through the fabric. In addition, the robot can scan RFID tags of objects within an area, for instance coupled to store inventory. Likewise, the robot can generate or update one or more semantic maps for use by the robot in navigating an area and for measuring compliance with security policies.
1. A mobile robot, comprising:
a motorized base configured to move the mobile robot throughout a room;
a wireless transceiver configured to communicatively couple to a security system;
a robot body on the motorized base comprising a spectrum analyzer configured to measure signals from electronic devices, wherein one or more electronic components of the mobile robot are disabled during scanning to avoid interference with the spectrum analyzer; and
a controller configured to:
access a map of the room in which the mobile robot is located;
cause the spectrum analyzer to scan, at a first location of the mobile robot within the room for unauthorized electronic devices;
modify the map of the room to include information indicating a presence or absence of unauthorized electronic devices based on the scan at the first location;
identify a second location within the room that has not be scanned using the accessed map; and
cause the motorized base to navigate to the second location within the room for scanning for unauthorized electronic devices.
2. The mobile robot of claim 1 , wherein accessing the map of the room further comprises:
capturing images of the room using a camera mounted to the mobile robot while navigating within the room; and
generating a map of the room based on the captured images.
3. The mobile robot of claim 1 , wherein the spectrum analyzer is mounted on an arm of the mobile robot coupled to the robot body.
4. The mobile robot of claim 1 , wherein the information representative of the scan is a detected signal that may originate from a detected unauthorized electronic device.
5. The mobile robot of claim 1 , wherein the controller is further configured to:
generate a heat map indicating locations within the room that the mobile robot has scanned for unauthorized electronic devices.
6. The mobile robot of claim 1 , wherein the map is modified to include a probability that unauthorized electronic devices are located at the first location.
7. The mobile robot of claim 6 , wherein responsive to the probability that the presence of unauthorized electronic devices are located at the first location exceeding a threshold, notifying a security personnel.
8. The mobile robot of claim 1 , wherein the controller is further configured to:
identify an unauthorized electronic device at the first location or the second location; and
responsive to identifying the unauthorized electronic device at the first location or the second location, remove, by the mobile robot, the unauthorized electronic device.
9. The mobile robot of claim 1 , wherein the controller is further configured to:
identify a person in the room; and
scan the person in the room for unauthorized electronic devices.
10. A method comprising:
accessing, by a mobile robot, a map of a room in which the mobile robot is located;
scanning, by a spectrum analyzer of the mobile robot, at a first location of the mobile robot within the room for unauthorized electronic devices, wherein one or more electronic components of the mobile robot are disabled during scanning to avoid interference with the spectrum analyzer;
modifying, by the mobile robot, the map of the room to include information indicating a presence or absence of unauthorized electronic devices based on the scan at the first location;
identifying, by the mobile robot, a second location within the room that has not been scanned using the accessed map; and
navigating, by the mobile robot, to the second location within the room to scan for unauthorized electronic devices.
11. The method of claim 10 , wherein accessing the map of the room further comprises:
capturing images of the room using a camera mounted to the mobile robot while the mobile robot navigates within the room; and
generating a map of the room based on the captured images.
12. The method of claim 10 , wherein the spectrum analyzer is mounted on an arm of the mobile robot.
13. The method of claim 10 , wherein the information representative of the scan is a detected signal that may originate from a detected unauthorized electronic device.
14. The method of claim 13 , further comprising:
generating a heat map indicating locations within the room that the mobile robot has scanned for unauthorized electronic devices.
15. The method of claim 10 , wherein the map is modified to include a probability that unauthorized electronic devices are located at the location.
16. The method of claim 15 , wherein responsive to the probability that the presence of unauthorized electronic devices are located at the location exceeding a threshold, notifying a security personnel.
17. The method of claim 10 , further comprising:
identifying an unauthorized electronic device at the first location or the second location; and
responsive to identifying the unauthorized electronic device at the first location or the second location, removing, by the mobile robot, the unauthorized electronic device.
18. The method of claim 10 , further comprising:
identifying a person in the room; and
scanning the person in the room for unauthorized electronic devices.
