## Detecting

This is the motion designator implementation of detecting, if an object with the given object type is in the field of
view (FOV) this motion designator will return an object designator describing the object.
view (FOV) this motion designator will return a list of object designators describing the objects. It is important to specify the
technique and state of the detection. You can also optional specify a region in which the object should be detected.


Since we need an object that we can detect, we will spawn a milk for this.
