cozmo.pets

Pet detection.

Cozmo is capable of detecting pet faces (cats and dogs).

The cozmo.world.World object keeps track of pets the robot currently knows about, along with those that are currently visible to the camera.

Each pet is assigned a Pet object, which generates a number of observable events whenever the pet is observed, etc.

If a pet goes off-screen, it will be assigned a new object_id (and therefore a new Pet object will be created) when it returns. This is because the system can only tell if something appears to be a cat or a dog; it cannot recognize a specific pet or, for instance, tell the difference between two dogs.

Note that these pet-specific events are also passed up to the cozmo.world.World object, so events for all pets can be observed by adding handlers there.
