Abstract

An unmanned vehicle for supplying feed to an animal, which is provided with a frame, with propulsion mechanism disposed thereon, feed supplier for supplying feed and navigator connected to the propulsion mechanism with a sensor for forming an image of an observation area, wherein the sensor comprises: a source of radiation for emitting modulated electromagnetic radiation, a receiver device for radiation reflected by an object, comprising a matrix with rows and columns of receivers, an optical device and sensor image processor configured to determine for the receivers a phase difference between the emitted electromagnetic radiation and the reflected electromagnetic radiation in order to calculate a distance from the receiver to the object. Through use of the unmanned vehicle device an excellent and reliable navigation is possible, so that, for example, milk can be conveyed efficiently from a milking implement to a calf.

Claims

1. Unmanned vehicle for supplying liquid feed to an animal, comprising a frame, with disposed thereon:

a propulsion mechanism;

a container for storing the liquid feed;

a feed supplier for supplying the liquid feed;

an animal identifier configured to supply an identification signal which is indicative of identity of the animal; and

a navigator connected to the propulsion mechanism with a sensor for forming an image of an observation area, the sensor comprising;

a source of radiation for emitting modulated electromagnetic radiation,

a receiver device for receiving electromagnetic radiation reflected by an object in the observation area, comprising a matrix with a plurality of rows and a plurality of columns of receivers,

an optical device for displaying imaging the reflected electromagnetic radiation on the receiver device, and

a sensor image processor configured to determine for each of the receivers a phase difference between the emitted electromagnetic radiation and the reflected electromagnetic radiation in order to calculate a distance from the receiver to the object and generate a spatial image thereof,

wherein the sensor image processor is configured to recognize at least one of a feed loading place, a feed unloading place, an animal, and a part of an animal based on the spatial image, and the navigator is controllable by the sensor image processor for controlling movement of the vehicle, and

wherein the feed supplier comprises an operable valve and a drinking nozzle movably supported on a height adjusting mechanism for vertical movement of said drinking nozzle with respect to the vehicle for supplying the liquid feed, the feed supplier being controllable by the sensor image processor and the identification signal for adjusting a height of the drinking nozzle for supplying feed for the identified animal.

2. The vehicle according to claim 1, wherein the sensor image processor configured to form a three-dimensional image of the observation area.

3. The vehicle according to claim 1, wherein the sensor image processor configured to form a three-dimensional image of an object in the observational area.

4. The vehicle according to claim 1, wherein at least one of the receiver device and the source of radiation is disposed at least one of rotatably and telescopically.

5. A device for supplying feed to an animal, comprising a vehicle according to claim 1 and a feed loading place, wherein the sensor image processor is configured to recognize a feed loading place, and the feed loading place comprises an autonomously displaceable milking implement.

6. The vehicle according to claim 1, wherein the sensor image processor is further configured to determine changes in the identified animal.

7. The vehicle according to claim 6, wherein the sensor image processor is further configured to determine a change in at least one of a height and a size of the identified animal.

8. The vehicle according to claim 6, wherein the feed supplier is mounted movably relative to the rest of the vehicle.

9. The vehicle according to claim 1, further comprising at least one of a connection for electrical feeding and a connection to a feed loading place for receiving feed, and wherein the sensor image processor is arranged to couple the connection to a counter-connection for that connection, by recognizing the connection and the counter-connection and minimizing the mutual distance between the connection and the counter-connection.

10. The vehicle according to claim 9, wherein the connection to the feed loading place is configured to receive liquid feed.

11. The vehicle according to claim 1, wherein the sensor image processor is configured to recognize a feed loading place, and the feed loading place comprises at least one of a milk storage vessel and a milking implement.

12. The vehicle according to claim 1, further comprising a milking implement with automatically connectable teat cups and a milk storage vessel.

13. The vehicle according to claim 1, wherein movement of the drinking nozzle of the feed supplier is controllable by the sensor image processor for bringing the nozzle to the mouth of the animal.

14. The vehicle according to claim 1, wherein the feed supplier is controllable for supplying a particular sort of feed based on the identification signal to the identified animal.

15. The vehicle according to claim 1, wherein the sensor image processor is configured to recognize the feed loading place, feed unloading place, animal, or part of an animal based on the spatial image and previously stored information regarding position and/or orientation of one or more reference objects.

16. The vehicle according to claim 1, wherein the height adjusting mechanism is configured to attune a position of the drinking nozzle to the dimensions of an animal by using a height adjusting device.

17. The vehicle according to claim 16, wherein the height adjusting mechanism adjusts the height of the drinking nozzle to a height of the identified animal at at least one feed unloading place.
