A robotic work tool system () comprising a robotic work tool () comprising a controller (), the controller () being configured to determine an area locality () associated with a hindrance; determine a classifier (C) associated with the area locality (); and determine an action for the robotic work tool (), wherein the action is based on the classifier (C).

Navigation for a robotic work tool

A robotic work tool system () for defining a working area () in which at least one robotic work tool () subsequently is intended to operate. The system () comprises at least one controller () 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 () moving within the working area (). The received sensor and event data are associated with each other in time. The controller () 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 () by relating positions associated with corresponding events with each other. The controller () 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 ().

Robotic work tool system and method for defining a working area

A robotic work tool system () comprising a robotic work tool (), the robotic work tool () being configured to determine () that the robotic work tool () has entered a state of limited movement; determine () an exit path; and exit () the state of limited movement by navigating the exit path.

Exit path determination for a robotic work tool

A robotic work tool system () for avoiding trails from a robotic work tool () in a transit zone () in which the robotic work tool () is allowed to travel from a start point () to a goal point () along a travel path (). The system () comprises at least one memory () configured to store information about the transit zone (), at least one robotic work tool () configured to travel along the travel path () and at least one controller () for controlling operation of the robotic work tool (). The controller () is configured to receive, from the memory (), information about the transit zone () and generate, based on the transit zone (), the travel path () for the robotic work tool () from the start point () to the goal point (). The generated travel path () is configured to differ from previously generated travel paths.
