ROBOTIC WORK TOOL SYSTEM AND METHOD FOR DEFINING A WORKING AREA

A robotic work tool system (200) for defining a working area (105) in which at least one robotic work tool (100) subsequently is intended to operate. The system (200) comprises at least one controller (210) being configured to receive sensor data for pose estimation and event data relating to a plur...

Summary:A robotic work tool system (200) for defining a working area (105) in which at least one robotic work tool (100) subsequently is intended to operate. The system (200) comprises at least one controller (210) being configured to receive sensor data for pose estimation and event data relating to a plurality of events of at least one robotic work tool (100) moving within the working area (105). The received sensor and event data are associated with each other in time. The controller (210) is configured to determine positions for the events based on the received sensor data associated with the respective event data and to determine features reflecting the working area (105) by relating positions associated with corresponding events with each other. The controller (210) is configured to adjust the determined positions based on the determined features by, for each feature, comparing the respective determined positions with each other; and determine, based on the adjusted positions, a map defining the working area (105).
