    Abstract: A method for switching a base station, a mower and a multi-base station working system are provided. The method includes: obtaining, when the number of first common-view satellites between the mower and a first base station is less than a first threshold, the number of second common-view satellites between the mower and a second base station; when the number of the first common-view satellites is less than a second threshold and the number of the second common-view satellites is greater than the second threshold, obtaining the first trajectory of the mower based on the first base station and the second trajectory of the mower based on the second base station; determining, based on the first and second trajectories, a coordinate transformation matrix; and switching from the first base station to the second base station based on the coordinate transformation matrix, the second threshold being less than the first threshold.

    Abstract: Disclosed are an automatic recharging method, a device, a storage medium and a system, which belong to the field of computer technology. The method may include: starting an image acquisition component to acquire an automatic recharging image during an automatic recharging process; determining, when the automatic recharging image contains a feature identification, the relative positional relationship between a charging surface of a charging base and the automatic recharging device based on the position of the feature identification in the automatic recharging image; displaying the feature identification on the charging surface of the charging base; determining a movement direction of the automatic recharging device based on the relative positional relationship, to make the automatic recharging device move toward the charging surface of the charging base.

    Abstract: A domestic robotic system includes a moveable robot having an image obtaining device for obtaining images of the exterior environment of the robot, and a processor programmed to detect a predetermined pattern within the obtained images. The processor and image obtaining device form at least part of a first navigation system for the robot which can determine a first estimate of at least one of the position and orientation of the robot. A second navigation system for the robot determines an alternative estimate of the at least one of the position and orientation of the robot. Calibration of the second navigation system can be performed using the first navigation system.

    Abstract: A robot lawnmower and method for controlling the robot lawnmower based on the generation of a local map. The method including receiving an image from an imaging sensor onboard the robot lawnmower, the image including an area of ground in an upcoming path, applying a semantic segmentation algorithm to produce a segmented image from the received image, the segmented image including regions corresponding to features in the image, applying a perspective transform to the segmented image to obtain an overhead view transformed image, wherein the regions are preserved in the transformed image, determining, from the transformed image, positions of the regions relative to the current position of the robot lawnmower, plotting a local map of the environment of the robot lawnmower based on positions of the regions relative to a current position of the robot lawnmower; and controlling the robot lawnmower to navigate a lawn area using the local map.

    Abstract: A method performed by a robotic garden system for controlling a robotic garden tool (1). The system comprises the robotic garden tool (1), a control unit, and a database. The method comprises the steps of: A. Retrieving a predetermined route (3) for a working area (4). The predetermined route (3) is based on a travel angle (6). The travel angle (6) is an angle extending from a starting point (7). The working area (4) delimits the travel of the robotic garden tool (1). A route data set comprises a plurality of predetermined routes. Each predetermined route has a travel angle substantially being different from all other travel angles of all other predetermined routes. B. Controlling the robotic garden tool (1) to start from the starting point (7) and move along the retrieved predetermined route (3).
