Abstract: An animal farm system includes a barn, animal related structures within the barn, such as a feeding alley and/or a milking system, and an autonomous vehicle arranged to perform an animal related action and move about in the barn. The vehicle includes a control unit to move the vehicle about, a position determining system for determining a position of the vehicle in the barn, a sensor system to determine a value of a parameter related to a position of the vehicle with respect to the barn or an object therein, such as the at least one structure therein, and a vehicle communication device. The control unit further is arranged to contain barn map information, and receive motion control and navigation information via the vehicle communication device.

Abstract: The invention provides a livestock feed-displacing device and system, with a grab bucket which can be positioned above a feed kitchen with feed positions by a control unit, wherein the control unit is designed to compose an amount of animal feed from feed material provided in the feed kitchen by positioning the grab bucket at a grabbing position, grabbing livestock feed underneath said grabbing position, positioning the grab bucket at a desired feed-unloading point, such as in a feed wagon, and unloading the grabbed livestock feed at the feed-unloading point, wherein the control unit is designed to earmark, if at least one predetermined clearing-up criterion has been met, livestock feed in the feed kitchen as waste to be removed and to make the device carry out a clearing-up operation, wherein the clearing-up operation comprises the removal of the livestock feed at said feed position by displacing it to another position in the feed kitchen.

Abstract: A method and an apparatus for roofing a structure or the like by erection of at least one frame and installation of a tent cloth therealong. The frame comprises various elements forming, in the erected position of the frame, roof and wall elements. The roof elements adjoin each other along a ridge line and the wall elements adjoin the roof elements along roof edge lines. The method and apparatus are characterized in that the frame has two frame halves hinged together in a flat starting position and lifted from that position by at least two points. The roof elements are lifted first on the side of the ridge line until the roof elements are at a given angle to each other, in which position there is provided between the roof elements a tie member which, in the loaded condition, defines an angle between the roof elements.

Abstract: A method of building a house or the like on a previously provided foundation, starting from a packaged structure comprising a plurality of panels, wherein, after the deposition of the package on the foundation, in successive stages a superjacent part of the package is hoisted up, and in the space thus formed the panels are unfolded, and packaged structure for use in said method.
