Abstract
A lift detection arrangement () in a robotic lawnmower for detecting a lift of a body () relative a chassis () of the robotic lawnmower is provided. The lift detection arrangement () comprises a connection between the chassis () and the body (). The connection comprises a joystick element () 5 arranged to allow a displacement of the body () relative the chassis () in a collision plane during a collision, and a lift element () arranged to provide a flexibility between the chassis () and the body () in a lift direction during the lift. The lift detection arrangement () further comprises a lift sensor configured to detect a displacement over a predetermined threshold of the lift element () 10 during the lift by detecting a change in spacing between two sensor parts (). One of the two sensor parts () is arranged on the lift element and the two sensor parts () are arranged to be relatively displaceable only in the lift direction.
