A control handle for a lawn mower includes a first lever and a second lever facing the first lever. Each lever is configured to actuate between an extended position and a depressed position. A controller is operatively associated with each of the first lever and the second lever so as to determine a position of the first lever with respect to the depressed position or the extended position of the first lever, and a position of the second lever with respect to the depressed position or the extended position of the second lever. Also, the first lever defines an interior having an opening facing the second lever such that the interior of the first lever is configured for receiving the second lever when at least one of the first lever and the second lever are actuated toward the respective depressed position.

The present disclosure relates to a robotic lawnmower fence (1) comprising a bracket (3) with two legs (9′, 9″), which are essentially straight and parallel, and a crossbar (11), which extends between upper ends (9′a, 9″a) of the two legs (9′, 9″) and perpendicular to the legs (9′, 9″). Opposite free ends (9′b, 9″b) of the legs (9′, 9″) are adapted to be anchored in the ground (17) and two support elements (5), each adapted to be arranged along respective leg (9′, 9″) in the extension direction (L) thereof to define a maximum depression depth (D) of the legs (9′, 9″) into the ground (17). The disclosure also relates to a fence system (49) comprising at least two fences (1).

A method (100) of assisting a user of a robotic tool system (10) is disclosed. The robotic tool system (10) comprises a self-propelled robotic tool (1) configured to operate an area in an autonomous manner and a docking station (3) for charging one or more batteries (5) of the robotic tool (1). The method (100) comprises the steps of obtaining (110) inclination data representative of an inclination angle (a0, a1, a2) of the robotic tool (1) when the robotic tool (1) is located on or at the docking station (3) and outputting (120) a notification (n0, n1, n2) based on the inclination data. The present disclosure further relates to a robotic tool (1) and a robotic tool system (10) comprising a robotic tool (1) and a docking station (3).

Quick release blade assemblies for a power tool are provided. A lawnmower includes a base including an engagement interface; a retainer having a locking component; a blade disposed between the base and the retainer; and an actuatable member including an engagement member, the engagement member being selectively displaceable with respect to the engagement interface between a locked configuration and an unlocked configuration when the actuatable member is translated in a direction parallel with the axis of rotation, wherein the engagement member is configured to interface with the locking component to selectively couple the blade to the drive shaft when the engagement member is in the locked configuration.

A system and method for environmental parameter mapping. A method includes adding at least one entry to a mapping data structure, wherein each entry includes a position of a robotic device and at least one corresponding environmental parameter for the respective position of the robotic device, wherein each environmental parameter of each entry indicates an attribute of an environment at the corresponding position and is based on at least one sensor signal captured at the corresponding position; and sending at least one command to the robotic device, wherein the at least one command is determined based on the mapping data structure and includes at least one command to navigate.
