A method for ascertaining information relating to a collection, a start and/or an end of a period spent in a workshop, in storage, and/or a delivery, of a green space and/or cultivated area treatment device, the method comprising the steps of:
- a) automatically providing a growth characteristic variable, wherein the growth characteristic variable is characteristic for plant growth on and/or in a space/area treated and/or to be treated by way of the green space and/or cultivated area treatment device;
- b) ascertaining the information on the basis of the provided growth characteristic variable;
- c) transmitting and/or outputting the ascertained information to a courier and/or delivery service, a workshop, a warehouse operator and/or a user, of the green space and/or cultivated area treatment device;
- wherein step b) comprises:
- ascertaining the information relating to the collection and/or the start of the period spent in the workshop and/or in the storage if the provided growth characteristic variable is characteristic for the plant growth falling below a growth limit value, and/or
- ascertaining the information relating to the end of the period spent in the workshop, the storage and/or the delivery if the provided growth characteristic variable is characteristic for the plant growth reaching and/or exceeding a growth limit value;
- wherein step a) comprises:
- automatically detecting the growth characteristic variable by way of a growth characteristic variable sensor in a region of the space/area;
- wherein the growth characteristic variable is averaged over several days or weeks, and/or several treatment processes of the space/area,
- wherein the information comprises an instruction relating to the start and/or the end of the period spent in a workshop and/or in storage, and
- wherein the green space and/or cultivated area treatment device is an autonomous mobile green space robotic lawnmower.
