Abstract

Systems, methods, and devices are disclosed for predictive shimming of large structures. Systems may include a remote device configured to move along a first path relative to a first vehicle structure. The remote device may be configured to move a sensor device along a plurality of measurement points included in the first path. A base device may be configured to identify a position of the sensor device at each measurement point. The base device may be configured to generate measurement data including a first plurality of measurements identifying at least one structural dimension of a first surface of the first vehicle structure. A controller may be configured to control operation of the base device and the remote device based on engineering data associated with the first vehicle structure. The controller may be further configured to determine at least one shim dimension associated with the first surface.

a base device communicatively coupled to the remote device and configured to identify a position of the sensor device of the remote device at each measurement point of the plurality of measurement points, the base device being further configured to generate measurement data identifying at least one structural dimension of a first surface of the first structure; and
a controller device communicatively coupled to each of the base device and the remote device, the controller device being configured to control operation of the base device and the remote device and further configured to determine at least one shim dimension associated with the first surface of the first structure, the at least one shim dimension based on the measurement data.

2. The system of claim 1 , wherein the sensor device comprises a tracking ball and a reflective device coupled to the tracking ball, and wherein the base device comprises a tracking device configured to be optically coupled with the reflective device.

3. The system of claim 2 , wherein the tracking ball is configured to mechanically couple with the first surface responsive to being within a designated distance of the first surface, wherein the mechanical coupling between the tracking ball and the first surface causes at least one change in a position of the tracking ball, and wherein the tracking device is configured to identify the change.

4. The system of claim 2 , wherein the tracking ball is coupled to a housing of the sensor device via a mechanical arm, the mechanical arm being configured to determine a position of the tracking ball.

5. The system of claim 1 , wherein the first surface of the first structure is included in an interface with a second surface of a second structure, and wherein the measurement data further comprises a first plurality of measurements associated with the first surface and a second plurality of measurements associated with the second surface.

6. The system of claim 5 , wherein the shim dimension is determined based, at least in part, on the first plurality of measurements and the second plurality of measurements.

7. The system of claim 1 , wherein base device is configured to move along a second path relative to the first structure, and wherein movement of the base device is based, at least in part, on metrology data identifying a first position of the first structure and a second position of the base device in an assembly environment.

8. The system of claim 1 , wherein movement of the remote device is based, at least in part, on engineering data.
