Abstract

A method and apparatus for laying composite tape. The method may comprise driving a plurality of robots, each having a respective movement system across a movement surface, in which the movement surface faces a workpiece, and laying composite tape from the plurality of robots in a coordinated manner on the workpiece.

First claim

What is claimed is:

1. A method comprising:
positioning a movement surface into an active position using a movement assembly configured to move a base relative to a workpiece, wherein the movement surface is a face of a base, and wherein the movement surface forms a substantially offset-surface relative to the workpiece when the movement surface is in the active position;
driving a plurality of robots, each having a respective movement system, across the movement surface and between the movement surface and the workpiece; and
laying composite tape from the plurality of robots in a coordinated manner on the workpiece.

2. The method of claim 1 , wherein laying the composite tape on the workpiece comprises moving a pedestal of a robot of the plurality of robots relative to the movement surface.

3. The method of claim 1 , wherein laying the composite tape on the workpiece comprises moving a tape laying head of a robot of the plurality of robots relative to the workpiece using a positioning system.

4. The method of claim 1 , wherein each of the plurality of robots comprise the respective movement system coupled to a pedestal, a positioning system coupled to the pedestal, and a tape laying head connected to the positioning system.

5. The method of claim 1 further comprising:
moving a first robot of the plurality of robots to an opposite side of a second robot of the plurality of robots on the movement surface using a movement system of the first robot.

6. The method of claim 1 further comprising:
moving a first robot of the plurality of robots to an edge of the movement surface using a movement system of the first robot; and
removing the first robot from the movement surface to perform maintenance on the first robot.

7. The method of claim 1 further comprising:
sensing relative positions of the plurality of robots while driving the plurality of robots across the movement surface to form sensor data; and
controlling movement of the plurality of robots based on the sensor data.

8. A method comprising:
positioning a base having a movement surface relative to a workpiece using a movement assembly connected to the base and configured to move the base relative to the workpiece such that the movement surface is in an active position relative to the workpiece wherein the movement surface forms a substantially offset-surface relative to the workpiece when the movement surface is in the active position;
moving a robot between the movement surface and the workpiece such that the robot lays composite tape on the workpiece, in which the robot comprises a movement system coupled to a pedestal, a positioning system coupled to the pedestal, and a tape laying head connected to the positioning system;
sensing positions of the tape laying head of the robots while moving the robot to form sensor data; and
controlling movement of the tape laying head based on the sensor data.

9. The method of claim 8 , wherein moving the robot associated with the movement surface comprises moving the tape laying head relative to the workpiece using at least one of the movement system or the positioning system to lay composite tape on the workpiece.

10. The method of claim 8 , wherein the robot is a first robot and further comprising:
moving a second robot past the first robot using a movement system of the second robot.

11. The method of claim 8 further comprising:
moving the robot relative to the workpiece by moving the robot on the movement surface using the movement system.
