An autonomous robotic lawnmower () is disclosed. The robotic lawnmower () comprises a driving unit () comprising one or more drive wheels () and a cutting unit () arranged to cut grass when in a cutting position relative a ground surface (). The lawnmower () further comprises a folding mechanism () allowing the cutting unit () to be pivoted relative the driving unit () around a pivot axis (ax) from the cutting position to a pivoted position.

The present disclosure relates to a lawnmower for processing lawn surface. The lawn mower comprises a chassis, at least partially carried by a set of wheels adapted to rest on the lawn surface, and one or more cutting devices suspended by the chassis. An outer cover, enclosing the chassis and is open towards the lawn surface to form an enclosed space between the outer cover and the lawn surface. A divider plate divides the enclosed space into an upper space and a cutting space, the divider plate generally extending along a plane that is approximately parallel with the lawn surface. The cutting device projects through an opening in the divider plate and edges of the divider plate are connected to the outer cover.

An outdoor robotic tool () comprising a switching assembly () comprising a carry handle () and a stop button () is disclosed. The carry handle () and stop button () are connected such that the raising of the carry handle () results in the stop button () being activated and vice versa. The activation of the stop button () results in the outdoor robotic tool () being rendered inoperable in some way. A lift-indication mechanism () may be present, which renders the outdoor robotic tool () inoperable if it is lifted. Either or both of the switching assembly () and lift-indication mechanism () may be present on the outdoor robotic tool ().

A robotic work tool having a chassis, a cover and a controller for controlling the operation of the robotic work tool. The robotic work tool further has a lift/collision detection device () connected to the controller for providing sensor input, and which Hft/coUision detection device () includes a first sensor element () and a second sensor element (). The controller () is configured to receive sensor input of a distance value indicating a distance between the first sensor element () and the second sensor element (), determine that a lift has been detected, fay comparing the distance value with a lift detection threshold and/or determine that a collision has been detected, by comparing the distance value with a collision detection threshold, wherein the collision detection threshold is different from the lift detection threshold.

A robotic vehicle () comprising a first chassis platform () comprising a first wheel assembly () and a second chassis platform () comprising a second wheel assembly (). The first and second chassis platforms () is arranged to be spaced apart from each other. The robotic vehicle () further comprises a linkage () operably coupled to the first chassis platform () and the second chassis platform (). The linkage () being coupled so as to be fixed relative to the first chassis platform () and so that the second chassis platform () is rotatable relative to the first chassis platform (), wherein the second chassis platform () comprises a turning axis (). Said robotic vehicle () further comprising an electric brake () disposed proximate to a turning shaft () of the linkage (). The electric brake () being selectively applied by processing circuitry () to resist turning of the second chassis platform () about the turning axis () and being selectively released to allow the second chassis platform () to turn about the turning axis ().

A robotic vehicle may include a first chassis platform including a first wheel assembly, a second chassis platform including a second wheel assembly where the first and second chassis platforms are spaced apart from each other, and a combination linkage operably coupling the first and second chassis platforms. The combination linkage may be operably coupled to the first chassis platform via a first link and is operably coupled to the second chassis platform via a second link. The combination linkage employs at least two different coupling features to operably couple the first and second chassis platforms. The at least two different coupling features include at least any two among a fixed attachment, an attachment that enables rotation about a turning axis, and an attachment that enables pivoting about a pivot axis that is substantially perpendicular to the turning axis.

A robotic work tool system may include a robotic work tool. The robotic work tool may include a stationary hub and a rotatable shaft being supported by the hub. Also, a hub cover is releasably attached to the hub. The robotic work tool further includes a skid plate extending radially outwards from the hub cover and the skid plate is arranged between the hub and the hub cover.
