a control device configured to control the drive device as a function of at least one of:

the type of rotor blade to be manufactured,

the current position of the carriage in a longitudinal direction of the rotor blade shell,

the type of bonding surface currently to be provided with adhesive, or

a position in space of the bonding surface currently to be provided with adhesive.

5. The device of claim 1 , wherein:

the holding device comprises an upper region, a lower region, and two lateral regions extending between the upper and lower regions;

the guide device is attached to one of the lateral regions of the holding device;

the at least one bonding surface comprises a first bonding surface along a first side of the rotor blade shell and a second bonding surface along a second side of the rotor blade shell, the second side of the rotor blade shell being opposite the first side of the rotor blade shell, and

the robot arm is dimensioned and configured such that it is able to apply adhesive to the first and second bonding surfaces while the carriage is movably supported by the guide device attached to said one lateral region of the holding device.

6. The device of claim 5 , wherein at least one of:

the first bonding surface is located towards said one lateral region of the holding device which the guide device is attached to; or

the robot arm is dimensioned and configured such that it is able to apply adhesive to the first and second bonding surfaces while the at least one web is attached to the rotor blade shell.

7. The device of claim 6 , wherein:

the robot arm is configured to reach over the at least one web in order to reach the second bonding surface.

8. The device of claim 1 , wherein:

the holding device comprises an upper region, a lower region, and two lateral regions extending between the upper and lower regions; and

the guide device is attached to one of the lateral regions of the holding device.

9. The device of claim 8 , wherein the upper region of the holding device comprises a negative mold configured for manufacturing the rotor blade shell.

10. The device of claim 1 , wherein the guide device is configured to guide the carriage along the holding device such that the at least one bonding surface is accessible to the robot arm.

11. The device of claim 1 , wherein the holding device comprises a negative mold configured for manufacturing the rotor blade shell.

12. The device of claim 1 , wherein the robot arm comprises at least one of:

at least two rotational axes; or

at least one translational axis.

13. The device of claim 1 , wherein:

at least one of the robot arm, the carriage, or the guide device is configured to at least one of:

guide a free end of the robot arm along the bonding surface, or

guide a free end of the robot arm towards the bonding surface; or

the bonding surface is located on at least one of:

a leading edge of the rotor blade shell,

a rear edge of the rotor blade shell, or

on a web attached to the rotor blade shell.

14. The device of claim 1 , wherein the nozzle is movably mounted on the robot arm.

15. The device of claim 1 , further comprising a feeding device adapted to feed adhesive to the nozzle.

16. The device of claim 1 , wherein:

the control device is further configured to control the valve device as a function of at least one of:

the current position of the carriage in a longitudinal direction of the rotor blade shell,

the type of bonding surface currently to be provided with adhesive, or

a position in space of the bonding surface currently to be provided with adhesive.

17. The device of claim 1 , further comprising:

a drive device configured to advance the carriage along the holding device; and

a control device configured to control at least one of the valve device or the drive device as a function of at least one of:

the type of rotor blade to be manufactured,

the current position of the carriage in a longitudinal direction of the rotor blade shell,

the type of bonding surface currently to be provided with adhesive, or

a position in space of the bonding surface currently to be provided with adhesive.
