## Abstract

A door opening and closing robot according to one or more embodiments may include a base; a robot arm connected to the base that includes an arm that is rotatable and a motor that rotates the arm; and a door operating tool that is connected to the robot arm and moves with a rotation of the arm. The robot arm drives the motor to rotate the door operating tool and detects presence of the door based on a change in torque of the motor.
