<p>An unmanned vehicle for supplying feed to an animal, which is provided with a frame, with propelling means disposed thereon, feed supplying means for supplying feed and navigation means connected to the propelling means with a sensor (24 - 28) for forming an image of an observation area, wherein the sensor (24, 28) comprises: a source of radiation (34) for emitting modulated electromagnetic radiation (36, 40), a receiver device for radiation (46) reflected by an object (44), comprising a matrix with rows and columns of receivers (50-1, 50-2, 50-3), an optical device (48) and sensor image processing means (52) arranged to determine for the receivers a phase difference between the emitted electromagnetic radiation (40) and the reflected electromagnetic radiation (46) in order to calculate a distance from the receiver (50-1, 50-2, 50-3) to the object (44). By means of such a device an excellent and reliable navigation is possible, so that, for example, milk can be conveyed efficiently from a milking implement to a calf.</p> |
