Abstract
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.
