A human robot communication method in which the robot decides the appropriate intervals : viol

in this research, we propose a human robot communication method in which the robot judges the reaction of the opponent in stages, decides the appropriate intervals according to the spot, and the robot shrinks or separates the distance himself. The robot himself measured the intersection from the expression and behavior of the opponent and designed and evaluated a service that allows the user to take a distance that allows the user to feel confident and comfortable communication.
