Any robot brought into the domestic environment must not be seen as a mere addition. It creates a biosymbiotic relationship between the robot and the owner. Two humans, living together, can easily understand the implicit signals of the other and can use their own knowledge of that person and themselves to make informed guesses about their future behaviour.
The robot relies on patterns and behaviours in it's charge in order to perform it's duties. It is not as adaptable as a human and can only understand explicit changes and instructions in it's environment. Any non-explicit duties it performs are calculated averages.
