  • Publication number: 20230189705
    Abstract: 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.

  • Publication number: 20210000008
    Abstract: A robotic work tool (100) comprising a chassis (110), a body (120) and a controller (400) for controlling operation of the robotic work tool (100) and at least one three-dimensional sensor arrangement (200) for detecting relative movement of the body (100) and the chassis (110), wherein the sensor arrangement (200) comprises a sensor element (210) arranged in one of the body (120) and the chassis (110) and a detection element (220) arranged in the other of the body (120) and the chassis (110), wherein the controller (400) is configured to: receive sensor input indicating relative movement of the sensor element (210) and the detection element (220) and; determine, from the sensor input, whether a collision or a lift has been detected.

  • Publication number: 20200128750
    Abstract: An outdoor robotic tool (100) comprising a switching assembly (104) comprising a carry handle (106) and a stop button (108) is disclosed. The carry handle (106) and stop button (108) are connected such that the raising of the carry handle (106) results in the stop button (108) being activated and vice versa. The activation of the stop button (108) results in the outdoor robotic tool (100) being rendered inoperable in some way. A lift-indication mechanism (126) may be present, which renders the outdoor robotic tool (100) inoperable if it is lifted. Either or both of the switching assembly (104) and lift-indication mechanism (126) may be present on the outdoor robotic tool (100).

  • Patent number: 8606390
    Abstract: A sewing machine (1) has access to a memory (M) for stitch data and a processor (C) for reading said stitch data and for operating the sewing machine (1) to execute stitches according to stitch data, wherein the sewing machine (1) has a hoop (20) for framing a pattern of the sewing material (2), and for moving the framed pattern in a direction comprising a component of at least one of a first coordinate (x) and a second coordinate (y) and wherein further the processor (C) controls movements of the hoop (20) according to said direction in relation to the position of a needle (5) of the sewing machine and synchronously with the movement of the needle for executing stitches, wherein: —the stretched sewing material (2) is clamped to the hoop (20) for forming a framed pattern in the hoop, —the framed pattern of the sewing material (2) is scanned by means of a camera (10) mounted in the sewing machine (1) and directed towards the sewing material (2) for the purpose of taking pictures of part views of said framed pa
