[0010] A base station according to the invention for a supply module, comprising at least one storage unit for receiving food, a dispensing unit for dispensing food received in the at least one storage unit, and an operating unit for selecting food to be dispensed, wherein the supply module is designed as an autonomous vehicle and comprises a drive unit for driving the supply module, an electrical energy storage device for supplying the drive unit, and a control unit for controlling the drive unit, comprises a filling unit for filling the at least one storage unit with food and a removal unit for removing undispensed food from the at least one storage unit.

[0011] The filling unit is preferably designed and arranged such that the at least one storage unit can be filled with food from a filling side of a housing unit. The dispensing unit is preferably designed and arranged such that undispensed food can be removed from the at least one storage unit from the filling side of the housing unit.

[0012] According to an advantageous embodiment of the invention, the base station further comprises a charging unit for the inductive transfer of energy to a receiving unit of the supply module.

[0013] Thus, the receiving unit of the supply module is able to inductively absorb energy from the charging unit and charge the electrical energy storage while the supply module is located at the base station.

[0014] According to an advantageous embodiment of the invention, the base station further comprises a communication unit for wireless communication via a radio network.

[0015] The communication unit can be used in particular to transmit a request for a supply module for an upcoming service, for example to fill the at least one storage unit with food, to the base station.

[0016] A method for operating a supply module and a base station according to the invention is also proposed. First, the at least one storage unit of the supply module is filled with food by the filling unit of the base station. At a defined time, the supply module navigates to a destination. The supply module remains at the destination for a defined period of time. After the defined period has elapsed, the supply module navigates back to the base station. Any undispensed food is removed from the at least one storage unit of the supply module by the dispensing unit of the base station.

[0017] The control unit of the supply module navigates the supply module to the destination and back to the base station using the map and by controlling the drive unit. The defined time is, for example, the start of a lunch break. The destination is, for example, a location near several workstations in a technical facility. The defined time period is, for example, the duration of the lunch break. The method according to the invention enables the dispensing of food stored in the at least one storage unit to people at the destination during the defined time period.

[0018] According to an advantageous embodiment of the invention, if a defined quantity of food is dispensed at the destination location via the dispensing unit during the defined time period, the supply module sends a corresponding message to the base station. Subsequently, the at least one storage unit of another supply module is filled with food by the filling unit of the base station. The additional supply module then navigates to the destination location.

[0019] The control unit of the additional supply module navigates the module to its destination using the map and by controlling the drive unit. If an unexpectedly large quantity of food is distributed to people at the destination via the dispensing unit during the defined time period, the additional supply module can transport the missing food to the destination to supply those present.

[0020] The invention is not limited to the combination of features stated in the claims. For a person skilled in the art, further meaningful combinations of claims and / or individual claim features and / or features of the description and / or the figures will become apparent, in particular from the problem statement and / or the problem arising from a comparison with the prior art.

[0021] The invention will now be explained in more detail with reference to the illustrations. The invention is not limited to the embodiments shown in the illustrations.
