I am not thinking of trying to give the robot the ability to make its own judgments. Sony has clearly stated that there was no need for a robot to be useful in terms of serving humans. Sony's robot is serving the humans by soothing people's heart. The difference between our robot and Sony's is that ours is meant to be useful for humans as a machine while Sony's robot appeals to people's hearts. However, what we must bear in our minds is that even when we are developing robots as useful machines, you cannot disregard their interaction with human beings.
People often become attached to their cars.
Making a robot move in accordance with your wishes might also give you a sense of attachment to the robot or the robot itself might feel some kind of affection to you. I intend to develop a robot based on the equation.
