Abstract: A robotic work tool system comprising a robotic work tool configured to operate in a work area comprising a lawn being of at least one lawn type, the robotic work tool comprising a controller configured to operate in the work area based on a work schedule, wherein the work schedule includes an indication of a work amount, wherein the robotic work tool system is characterized in that the work amount is dependent on the lawn type.

Abstract: A method and device applicable to a sewing machine which has a needle and a gripper with a horizontally positioned lower bobbin for executing a seam with stitches in a sewing material being sewn, for compensating a deficiency in a longitudinal shift of the needle during a stitch being caused by an arcuate movement of the needle when it shifts sideways in a stitch, wherein the method includes the material being advanced by a feeder a length yn in the longitudinal direction of the seam on the basis of the seam setting, and wherein the sewing machine has a control including an algorithm causing the feed motor to set the feeder, so that at each stitch which includes sideways shifts of the needle it advances the sewing material a correction length en in the longitudinal direction of the seam, thereby compensating a corresponding deficiency in the needle's longitudinal shift relative to the material during the stitch being caused by the needle's arcuate sideways movement.

Abstract: A sewing order is determined in embroidering at least one embroidery element on a sewing material in a sewing machine, which has access to a memory for stitch data for the embroidery element and a processor for reading the stitch data and for maneuvering the sewing machine to execute stitches according to the stitch data. An embroidery element is composed of basic elements, through a formation of clusters of basic elements having the same characteristics. A level for each cluster is determined. The clusters are sorted with regards to their respective characteristics and sorting of the clusters into a sewing order based on characteristics and levels of the clusters.

Abstract: A method and an arrangement for placing an embroidery in the desired position on a sewing material for embroidering on a sewing machine which has a memory for embroidery elements and a processor for reading stitch data for a selected embroidery element and for manoeuvring the sewing machine to execute stitches associated with the selected embroidery element on the sewing material, in which pattern points are assigned to the embroidery element and registered in the processor, and in which fabric points are marked on the sewing material at points where corresponding pattern points are to be located when embroidering, the sewing machine processor automatically orienting and scaling executed patterns of the embroidery element on the sewing material.
