Abstract:
A robotic work tool system, comprising a robotic work tool, said robotic work tool comprising a position determining device for determining a current position and at least one deduced reckoning (also known as dead reckoning) navigation sensor, the robotic work tool being configured to determine that a reliable and accurate current position is possible to determine and in response thereto determine an expected navigation parameter, compare the expected navigation parameter to a current navigation parameter to determine a navigation error, determine if the navigation error is negligible, and if the navigation error is not negligible, cause the robotic work tool to change its trajectory to accommodate for the navigation error. Wherein the robotic work tool (100) is further configured to change the trajectory by aligning the trajectory with an expected trajectory, wherein the expected trajectory is determined as an expected direction originating from an expected position and wherein the robotic work tool (100) is configured to change the trajectory by returning to a position that should have been visited and aligning the trajectory with the expected direction originating from the expected position, said position that should have been visited being aligned with the expected direction originating from the expected position.
Abstract:
A robotic vehicle may include one or more functional components configured to execute a lawn care function, a sensor network comprising one or more sensors configured to detect conditions proximate to the robotic vehicle, and a monitoring module configured to monitor data gathered via the sensor network responsive to traversing the parcel. The monitoring module may also selectively initiate an alarm or notification function in response to the data indicating the occurrence of a trigger event.

Abstract:
A robot lawnmower (10) includes a robot body (100), a drive system (400), a localizing system (550), a teach monitor (600), and a controller (150) in communication with one another. The drive system is configured to maneuver the robot lawnmower over a lawn. The teach monitor determines whether the robot lawnmower is in a teachable state. The controller includes a data processing device (152a) and non-transitory memory (152b) in communication with the data processing device. The data processing device executes a teach routine (155) when the controller is in a teach mode for tracing a confinement perimeter (21) around the lawn (20) as a human operator pilots the robot lawnmower, when the robot lawnmower is in the teachable state, the teach routine stores global positions determined by the localizing system in the non-transitory memory, and when the robot lawnmower is in the unteachable state, the teach routine issues an indication of the unteachable state.
