Claim:
An unmanned autonomous vehicle for displacing feed lying on a floor substantially laterally with respect to a direction of operative travel, the unmanned autonomous vehicle comprising: a frame having at least three supporting points, comprising a front supporting point and two wheels separately drivable by separate motors and each having a wheel axle, a control unit for steering and moving the vehicle, and feed displacer for displacing feed substantially laterally, comprising an annular element which is freely rotatable around the frame and has a radius, the outer circumference of said element constituting the outer circumference of the vehicle, wherein a centre of gravity of the vehicle, viewed in the direction of operative travel, is situated between the front supporting point and the wheels, wherein, viewed perpendicularly to the direction of operative travel and in side view, a distance between each of the wheel axles and a perpendicular line through a geometric centre of the feed displacer amounts to less than one third of said radius.
