Abstract

Systems and methods for virtually displaying a robotic device to a human operator. An exemplary system includes an augmented reality headset for use by the human operator. The system includes a first imaging device having a field of view of a first side of an object, and tracks coordinate data for a first marker on the robotic device positioned on the first side. The system includes a second imaging device having a field of view of a second side of the object, and tracks coordinate data for a second marker on the augmented reality headset positioned on the second side. The system includes a controller that generates a virtual image of the robotic device in a coordinate system based on the coordinate data for the first and second markers, and provides the virtual image of the robotic device to the augmented reality headset for display to the human operator.

First claim

The invention claimed is:

1. A system comprising:
a robotic device having a tool configured to perform work on an object, wherein a first fiducial marker is attached to the tool, and wherein the robotic device is positioned at a first side of the object;
an augmented reality headset for use by a human operator positioned at a second side of the object that opposes the first side such that the object obstructs a line of sight between the human operator and the robotic device, wherein a second fiducial marker is attached to the augmented reality headset;
a first imaging device having a field of view of the first side of the object, and configured to track coordinate data for the first fiducial marker as the first fiducial marker moves with the tool of the robotic device;
a second imaging device having a field of view of the second side of the object, and configured to track coordinate data for the second fiducial marker as the second fiducial marker moves with the augmented reality headset used by the human operator; and
a controller configured to generate a virtual image of the tool of the robotic device in a coordinate system based on the coordinate data for the first fiducial marker and the coordinate data for the second fiducial marker, and to provide the virtual image of the tool of the robotic device to the augmented reality headset for display to the human operator.

2. The system of claim 1 wherein:
the first fiducial marker and the second fiducial marker each include a plurality of references points having a Light Emitting Diode (LED).

3. The system of claim 1 wherein:
the controller includes:
a virtual data storage configured to store virtual data for different types of tooling on an end effector of the robotic device; and
a virtual image generator configured to identify tooling on the end effector, to retrieve the virtual data for the tooling from the virtual data storage, and to generate the virtual image of the robotic device based on the virtual data for the tooling.

4. The system of claim 3 wherein:
the virtual image generator is configured to read a Radio Frequency Identification (RFID) tag to identify the tooling on the end effector.

5. The system of claim 1 wherein:
the first imaging device includes:
at least one camera; and
a processor that uses photogrammetry to track the coordinate data for the first fiducial marker.

6. The system of claim 1 wherein:
the controller is configured to provide the coordinate data for the second fiducial marker on the augmented reality headset to the robotic device.

7. The system of claim 1 wherein:
the object comprises a component of an aircraft.

8. A method comprising:
tracking, with a first imaging device, coordinate data for a first fiducial marker attached to a tool of a robotic device as the first fiducial marker moves with the tool, wherein the robotic device is positioned at a first side of an object, and wherein the first imaging device is positioned with a field of view of the first side of the object;
tracking, with a second imaging device, coordinate data for a second fiducial marker attached to an augmented reality headset worn by a human operator, wherein the augmented reality headset is positioned at a second side of the object such that the object obstructs a line of sight between the human operator and the robotic device, and wherein the second imaging device is positioned with a field of view of the second side of the object;
generating a virtual image of the tool of the robotic device in a coordinate system based on the coordinate data for the first fiducial marker and the coordinate data for the second fiducial marker; and
providing the virtual image of the tool of the robotic device to an augmented reality headset for display to the human operator.

9. The method of claim 8 wherein:
the first fiducial marker and the second fiducial marker each include a plurality of references points having a Light Emitting Diode (LED).

10. The method of claim 8 further comprising:
storing virtual data for different types of tooling on an end effector of the robotic device;
identifying tooling on the end effector;
retrieving the virtual data for the tooling; and
generating the virtual image based on the virtual data for the tooling.

11. The method of claim 10 wherein identifying tooling on the end effector comprises:
reading a Radio Frequency Identification (RFID) tag to identify the tooling on the end effector.

12. The method of claim 8 further comprising:
providing the coordinate data for the second fiducial marker on the augmented reality headset to the robotic device.

13. The method of claim 8 wherein:
the object comprises a component of an aircraft.

14. A positioning system for virtually displaying a robotic device to a human operator, the positioning system comprising:
an augmented reality headset for use by the human operator;
a first imaging device having a field of view of a first side of an object, and configured to track coordinate data for a first fiducial marker attached to an end effector of the robotic device, wherein the robotic device is positioned on the first side of the object, and wherein the augmented reality headset is positioned at a second side of the object such that the object obstructs a line of sight between the human operator and the robotic device;
a second imaging device having a field of view of the second side of the object that opposes the first side, and configured to track coordinate data for a second fiducial marker attached to the augmented reality headset, wherein the augmented reality headset is positioned on the second side of the object; and
a controller configured to generate a virtual image of the end effector of the robotic device in a coordinate system based on the coordinate data for the first fiducial marker and the coordinate data for the second fiducial marker, and to provide the virtual image of the end effector to the augmented reality headset for display to the human operator.
