Production line and method for operating such

1. A production line for manipulating objects comprising:

a plurality of working stations arranged one after another for performing consecutive working steps on the objects, each working station being arranged for at least one working step to be performed by a stationary operator,

wherein at least one working station is arranged for a stationary operator that is a human and at least one working station is arranged for a stationary operator that is a robot,

wherein said at least one working station for a stationary operator that is a human and said at least one working station for a stationary operator that is a robot are arranged such that transfer of objects from one working station to the other working station is performed by one or both of said stationary operators, wherein the working range of the stationary operator that is a robot in one working station at least partly overlaps the working range of the stationary operator that is a human in a neighboring working station, and

wherein the stationary operator that is a robot has at least two arms.

2. The production line of claim 1 , wherein the production line is an assembly line and wherein at least one of the working stations is arranged for adding at least one component to each object.

3. The production line of claim 1 , wherein each robot arm has at least seven degrees of freedom.

4. The production line of claim 1 , wherein the robot arms are at least partly covered by a soft padding.

5. The production line of claim 1 , wherein each robot arm in the robot having at least two arms is driven at a power that is less than 80 W.

6. The production line of claim 1 , wherein at least one of the working stations is arranged to be operated either by a robot or by a human.

7. The production line of claim 1 , wherein the working range of at least one robot corresponds to the working range a human would reach if located at the location of the robot.

8. The production line of claim 7 , wherein a working station equipped with a robot includes at least one component storage and at least one fixture being arranged such that the at least one component storage and the at least one fixture would be usable by a human if located at the location of the robot.

9. A method for operating a production line, the method comprising:

providing a plurality of working stations arranged one after another for performing consecutive working steps on objects, each working stations being arranged for at least one working step to be performed by an operator; and

performing consecutive working steps on the objects, where at least one working step is performed at each working station, and where the working step in at least one working station is performed by an operator being a human and the working step in at least one working station is performed by an operator being a robot,

wherein the working stations are arranged such that the working range of the operator that is a robot in one working station at least partly overlaps the working range of the operator that is a human in a neighboring working station,

wherein the transfer of objects from one working station where the working step is performed by a human to the other working station where the working step is performed by a robot is performed by one or both of said human and said robot, and

wherein operations performed by the robot are performed by at least two robot arms.

10. The method of claim 9 , wherein the method includes assembling work where the working step of at least one of the working stations includes adding a component to the object.

11. The method of claim 9 , wherein the objects are temporarily stored between neighboring working stations and that an operator, whether a robot or a human, at both neighboring working stations drops or picks up respectively a temporarily stored object.
