Abstract:
A lift detection arrangement (100, 200) in a robotic lawnmower for detecting a lift of a body (110, 210) relative a chassis (105, 205) of the robotic lawnmower is provided. The lift detection arrangement (100, 200) comprises a connection between the chassis (105, 205) and the body (110, 220). The connection comprises a joystick element (115, 215) 5 arranged to allow a displacement of the body (1110, 210) relative the chassis (105, 205) in a collision plane during a collision, and a lift element (120, 220) arranged to provide a flexibility between the chassis (105, 205) and the body (110, 210) in a lift direction during the lift. The lift detection arrangement (100, 200) further comprises a lift sensor configured to detect a displacement over a predetermined threshold of the lift element (120, 220) 10 during the lift by detecting a change in spacing between two sensor parts (125, 126, 225, 226). One of the two sensor parts (125, 126, 225, 226) is arranged on the lift element and the two sensor parts (125, 126, 225, 226) are arranged to be relatively displaceable only in the lift direction.
Abstract:
A robotic lawnmower comprises, inter alia, a chassis (2), a body which is movably fitted to the chassis by means of at least one suspension (7, 8) and at least one collision sensor for detecting an obstacle by sensing a movement of the body relative to the chassis when the lawnmower collides with the obstacle, and for providing sensor signals indicative thereof for bringing the lawnmower to respond, e.g. stop or change traversing direction. The suspension (7, 8) comprises a joystick element (12) by means of which the body is fitted to the chassis (2) and a resilient positioning member (13) for holding the joystick element in a neutral position (N). The resilient positioning member (13) also permits movement of the joystick element (12) when the lawnmower collides with the obstacle and the body moves relative to the chassis (2), and return of the joystick element to the neutral position (N) after the collision. The resilient positioning member (13) of the suspension (7, 8) is a spring element (14) of a time and wear resistant material.
