a robot carrier comprising a vertical lift mounted on a base, wherein the vertical lift comprises a vertical column and a shelf, wherein the shelf is movably attached to the vertical column and is movable along a vertical direction, and wherein the base has a base central axis, wherein the vertical lift and the base are configured to be independently rotatable around the base central axis during an assembling process of the frame; and
a robot mounted on the shelf and configured to assemble the frame;
wherein the positioner is configured to lift the fixture table up and down, to rotate the fixture table around a positional axis, and to tilt the fixture table to support the frame anywhere between a vertical position and a horizontal position during the assembling process of the frame.

2. The manufacturing cell of claim 1 , wherein the robot has six degrees of freedom, and wherein the robot carrier and the robot have eight degrees of freedom together.

3. The manufacturing cell of claim 1 , wherein the robot carrier further comprises a control unit, and wherein the control unit is configured to control the robot carrier.

4. The manufacturing cell of claim 1 , wherein the positioner is configured to rotate the fixture table.

5. The manufacturing cell of claim 1 , wherein the positioner further comprises a three point kinematic mount.

6. The manufacturing cell of claim 1 , further comprising a mechanical lock, wherein the mechanical lock is configured to lock the fixture table to the positioner, and wherein the positioner is configured to support the fixture table at the vertical position, the horizontal position, and anywhere between the vertical position and the horizontal position.

7. The manufacturing cell of claim 1 , wherein the positioner further includes a backbone, and wherein the backbone is configured to be movable from the horizontal position to the vertical position.

8. The manufacturing cell of claim 1 , wherein the fixture table further includes a backbone, and wherein the backbone is configured to be coupled to the positioner.

9. The manufacturing cell of claim 1 , further comprising a second robot carrier.

10. The manufacturing cell of claim 1 , further comprising a fastener driver, wherein the robot further comprises an arm, and wherein the fastener driver is attached to the arm of the robot, wherein the robot is further configured to install fasteners to the frame by using the fastener driver.

11. The manufacturing cell of claim 1 , further comprising a metrology device, wherein the robot further comprises an arm, and wherein the metrology device is attached to the arm of the robot, wherein the robot is further configured to measure multiple points on the frame for measurement of the frame by using the metrology device.

12. The manufacturing cell of claim 1 , further comprising a tool changer and a plurality of end effectors, and wherein the tool changer is configured to exchange the plurality of end effectors for the robot.

13. The manufacturing cell of claim 1 , further comprising one or more stationary robots.

14. The manufacturing cell of claim 1 , further comprising a tool table and a plurality of end effectors, and wherein the tool table is configured to hold the plurality of end effectors.

15. The manufacturing cell of claim 1 , further comprising a controller configured to control the assembling process of the frame.

16. The manufacturing cell of claim 1 , further comprising a safety sensor configured to provide a safety measure to the manufacturing cell.

17. The manufacturing cell of claim 1 , further comprising one or more subassembly robots and one or more subassembly tables, wherein each of the one or more subassembly robots is configured to assemble a subassembly of the frame on a corresponding one of the one or more subassembly tables.

18. The manufacturing cell of claim 1 , wherein the fixture table comprises a modular fixture table including a plurality of locating and securement features, and a plurality of movable support plates.

19. The manufacturing cell of claim 1 , wherein the robot has a robot central axis, wherein the robot is configured to rotate around the robot central axis.

20. The manufacturing cell of claim 19 , wherein the robot central axis is offset from the base central axis such that the robot is further rotatable about an arc movement around the base central axis.

21. The manufacturing cell of claim 1 , wherein the robot is further configured to apply an adhesive to bond the frame.

22. The manufacturing cell of claim 21 , further comprising an adhesive injection subsystem, the adhesive injection subsystem comprises a plurality of adhesive injection end effectors.

23. A system for manufacturing a vehicle, the system comprising:
a fixture table configured to hold a frame of the vehicle;
a manufacturing cell configured for assembling the frame, the manufacturing cell comprising:
a positioner configured to receive the fixture table,
a robot carrier comprising a vertical lift mounted on a base wherein the base has a base central axis, wherein the vertical lift and the base are configured to be independently rotatable around the base central axis during an assembling process of the frame,
a robot mounted on the robot carrier and configured to assemble the frame; and

a controller configured to control the assembling process of the frame;
wherein the positioner is configured to lift the fixture table up and down, to rotate the fixture table around a positional axis, and to tilt the fixture table to support the frame anywhere between a vertical position and a horizontal position during the assembling process of the frame.

24. The system of claim 23 , wherein the vertical lift of the robot carrier comprises a vertical column and a shelf movably attached to the vertical column, wherein the shelf is movable along a vertical direction, and wherein the robot is mounted on the shelf.
