Abstract: An autonomous lawn mower includes removable batteries, one or more electric motors, a cutting blade, one or more wheels, an angle sensor, and a controller. The cutting blade is driven by one of the electric motors. The wheels are driven by one of the electric motors. The controller is configured to allow the lawn mower to perform a grass cutting function at a jobsite without human interaction. The controller is configured to determine whether a roll angle is greater than a first predefined amount using data from the angle sensor. In response to determining the roll angle is greater than the first predefined amount, the controller is configured to stop operation of one of the one or more electric motors configured to provide rotational drive power to the cutting blade.

Abstract: A system provided for use with a lawn mower includes a processor in communication with the lawn mower. The processor is configured to acquire geographic location data of the lawn mower and mapping data for the lawn mower as the lawn mower operates on the plot of land. The processor is configured to acquire performance data of the lawn mower as the lawn mower operates on the plot of land according to a first path and generate a map of the plot of land at least partially based on the geographic location data and the mapping data. The processor is configured to determine an operational efficiency of the lawn mower according to the first path and determine a second path for the lawn mower that increases the operational efficiency of the lawn mower for operating on the plot of land.

Abstract: 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).

Abstract: A robot lawnmower includes a robot body, a drive system, a localizing system, a teach monitor, and a controller 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 and non-transitory memory in communication with the data processing device. The data processing device executes a teach routine when the controller is in a teach mode for tracing a confinement perimeter around the lawn as a human operator pilots the robot lawn mower, 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.
