Why is the awareness limited?

If I am not this body. Then Why am I only Aware of this body?

I think it was a choice. I like to use the analogy of a robot vaccum cleaner. The robot vac has a camera and other Environment sensory components. And The User can choose to use a mobile device to view through the camera of the robot vac Now what has happened is that we are stuck there. we Think we are the robot vac. but we are not the robot vac. We can see through the camera of the robot vac but we cant see the robot vac it self. But we are not the robot vac. just like it is possible to stop looking at the camera of the robot vac. if it is true that I am not this body - then it may be true that I can stop looking through the camera (eyes) of this body and become aware of more than this body.
