"""Object and Light Cube recognition. Vector can recognize and track a number of different types of objects. These objects may be visible (currently observed by the robot's camera) and tappable (in the case of the Light Cube that ships with the robot). The Light Cube is known as a :class:`LightCube` by the SDK. The cube has controllable lights, and sensors that can determine when it's being moved or tapped. Objects can generate events which can be subscribed to from the anki_vector.events class, such as object_appeared (of type EvtObjectAppeared), and object_disappeared (of type EvtObjectDisappeared), which are broadcast based on both robot originating events and local state. All observable objects have a marker of a known size attached to them, which allows Vector to recognize the object and its position and rotation ("pose"). You can attach markers to your own objects for Vector to recognize by printing them out from the online documentation. They will be detected as :class:`CustomObject` instances. Vector connects to his Light Cube with BLE.
