Unmanned vehicle for displacing manure

An unmanned vehicle for performing activities in a space in which at least one animal is present, comprising a frame, with mounted thereon:

• a propulsion mechanism and a navigation mechanism, wherein the vehicle further comprises a sensor for forming an image of an observation area, the sensor comprising a sensor image processor operatively connected to the navigation mechanism, and
• wherein at least one of the sensor image processor and the navigation mechanism is configured to:
• detect at least a part of the at least one animal, and
• determine whether a current course of the unmanned vehicle will lead to a collision with the animal, wherein the at least one of sensor image processor and navigation mechanism, if the current course of the unmanned vehicle will lead to a collision with the detected animal, subsequently:
• determine at least a first priority parameter from a set of one or more priority parameters of the detected animal, wherein the first priority parameter is a standing condition of the detected animal,
• decide, on the basis of the set of priority parameters of the detected animal, whether the course of the unmanned vehicle will be adjusted to avoid the detected animal, wherein the course of the unmanned vehicle will be maintained if the set of priority parameters meets a predetermined collision criterion, and the course of the unmanned vehicle will be adjusted to avoid the detected animal if the set of priority parameters does not meet the predetermined collision criterion,
• wherein the set of priority parameters only meets the predetermined collision criterion if at least the standing condition of the detected animal if that the detected animal is standing, and
• wherein the set of priority parameters does not meet the predetermined collision criterion if the standing condition of the detected animal is that the detected animal is not standing.
