A robotic work tool (100) comprising a chassis (110) and a body (120). The robotic work tool (100) further comprises at least one input unit (170, 180) for receiving input data relating to an operation of the robotic work tool (100), and at least one collision sensor arrangement (140) for detecting a direction of a movement of the chassis (110) with respect to the body (120). The movement is indicative of a collision. The robotic work tool (100) further comprises at least one controller (130) for controlling operation of the robotic work tool (100). The at least one controller (130) is configured to receive, from the at least one input unit (170, 180), said input data relating to the operation of the robotic work tool (100). The at least one controller (130) is further configured to adapt a collision threshold based on said input data relating to the operation of the robotic work tool (100). The collision threshold is related to said movement of the chassis (110) with respect to the body (120) detected by the at least one collision sensor arrangement (140).
