System comprising a central control device and a cell for handling and/or machining workpieces, for example furniture parts, which preferably consist at least partly of wood, wood-based materials, plastics or the like, the cell having: at least one mobile guide machine, preferably an industrial robot, for handling and/or machining the workpieces, wherein the mobile guide machine has: at least one operating arm which extends from a base of the mobile guide machine so as to be moveable in at least two axes, preferably at least three axes, particularly preferably six axes, and at least one interface which is arranged on the base of the mobile guide machine, wherein the mobile guide machine is designed in such a way that it can be set up or dismantled on a supporting surface without anchoring and is moveable, preferentially autonomously, and wherein the cell also has: at least one accessory device (10.1, 10.2, 10.3) which is coupled by means of the at least one interface of the mobile guide machine to configure the design of the cell, characterised in that the at least one interface is designed in such a way that it makes possible a connection and a referencing and/or alignment and a data exchange with the accessory device (10.1, 10.2, 10.3), the interface is designed to make possible a referencing and/or alignment of the accessory device (10.1, 10.2, 10.3) relative to the mobile guide machine, mechanically and virtually, by means of GPS position data, radar positioning, or by means of optical markings, the cell is also arranged on the central control device, which is designed to detect states of the mobile guide machine and the at least one accessory device (10.1, 10.2, 10.3) and is also designed to optimise process sequences by means of the states detected in the cell. at least one operating arm which extends from a base of the mobile guide machine so as to be moveable in at least two axes, preferably at least three axes, particularly preferably six axes, and at least one interface which is arranged on the base of the mobile guide machine, wherein the mobile guide machine is designed in such a way that it can be set up or dismantled on a supporting surface without anchoring and is moveable, preferentially autonomously, and wherein the cell also has: at least one accessory device (10.1, 10.2, 10.3) which is coupled by means of the at least one interface of the mobile guide machine to configure the design of the cell, characterised in that the at least one interface is designed in such a way that it makes possible a connection and a referencing and/or alignment and a data exchange with the accessory device (10.1, 10.2, 10.3), the interface is designed to make possible a referencing and/or alignment of the accessory device (10.1, 10.2, 10.3) relative to the mobile guide machine, mechanically and virtually, by means of GPS position data, radar positioning, or by means of optical markings, the cell is also arranged on the central control device, which is designed to detect states of the mobile guide machine and the at least one accessory device (10.1, 10.2, 10.3) and is also designed to optimise process sequences by means of the states detected in the cell. at least one accessory device (10.1, 10.2, 10.3) which is coupled by means of the at least one interface of the mobile guide machine to configure the design of the cell, characterised in that the at least one interface is designed in such a way that it makes possible a connection and a referencing and/or alignment and a data exchange with the accessory device (10.1, 10.2, 10.3), the interface is designed to make possible a referencing and/or alignment of the accessory device (10.1, 10.2, 10.3) relative to the mobile guide machine, mechanically and virtually, by means of GPS position data, radar positioning, or by means of optical markings, the cell is also arranged on the central control device, which is designed to detect states of the mobile guide machine and the at least one accessory device (10.1, 10.2, 10.3) and is also designed to optimise process sequences by means of the states detected in the cell.
