1. A method for calibrating a robot, the method comprising:
moving a robot such that a reference point of the robot is located at a first position within a working space of the machine tool and/or production machine;
comparing a first position value for the robot at the first position with a first position value for the machine tool and/or production machine at the first position; and
based on the comparing, when the first position value for the robot differs from the first position value for the machine tool and/or production machine, the first position value for the robot is corrected, or the first position value for the machine tool and/or production machine is corrected, such that the first position value for the robot and the first position value for the machine tool and/or production machine are the same, wherein a working space of the robot at least partially overlaps a working space of the machine tool and/or the production machine.
 
13. A system, comprising:
a robot;
a machine tool and/or production machine arranged such that a working space of the robot at least partially overlaps a working space of the machine tool and/or production machine; and
a controller configured to move the robot such that a reference point of the robot is located at a first position within the working space of the machine tool and/or production machine; compare a first position value for the robot at the first position with a first position value for the machine tool and/or production machine at the first position; and based on the comparing, when the first position value for the robot differs from the first position value for the machine tool and/or production machine, correct the first position value for the robot, or correct the first position value for the machine tool and/or production machine, such that the first position value for the robot and the first position value for the machine tool and/or production machine are the same.
