1. A robot for mimicking a posture of a user, the robot comprising:
a case;
a camera disposed in the case, and configured to photograph the user and generate a captured image;
a display disposed in the case and configured to reproduce a display image;
an electronic control unit configured to communicate with the camera and the display,
wherein the electronic control unit derives heart rate information from the captured image, and changes the display image such that the display image corresponds to the heart rate information,
wherein the electronic control unit communicates with a pad that senses a magnitude and a distribution of pressures applied by both feet of the user to generate posture information from a pressure signal, and changes the display image such that the display image corresponds to the posture information,
wherein the display image includes at least one of a background image, a letter, a number, a symbol, a graph, and an emoji, which correspond to the heart rate information, and at least one of a background image, a letter, a number, a symbol, a graph, and an emoji, which correspond to the posture information,
wherein the at least one of the background image, the letter, the number, the symbol, the graph, and the emoji, which correspond to the heart rate information, and the at least one of the background image, the letter, the number, the symbol, the graph, and the emoji, which correspond to the posture information are reproduced at the same time or alternately,
wherein the electronic control unit classifies the posture of the user into any one of a correct posture, a poor upper body posture, and a posture with crossed legs,
wherein the poor upper body posture includes at least one of a first posture, in which an upper body or a neck of the user is bent to any one of an upper side, a lower side, a left side, and a right side, and a second posture, in which a body of the user is leaned or supported by any one of both legs of user, and
wherein the at least one of the background image, the letter, the number, the symbol, the graph, and the emoji corresponding to the posture information is differently expressed according to the posture of the user;
a first leg and a second leg driven to correspond to the posture information in the posture with the crossed legs, and
a first driver configured to drive the first leg and the second leg,
wherein the first driver includes:
a first motor;
a rack gear configured to move to one side and an opposite side by the first motor;
a first driven gear disposed in the first leg; and
a second driven gear disposed in the second leg,
wherein the rack gear moves to the one side to be enmeshed with the first driven gear through forward rotation driving of the first motor to rotate the first driven gear,
wherein the rack gear moves to the opposite side to be enmeshed with the second driven gear through reverse rotation driving of the first motor to rotate the second driven gear, and
wherein axes of rotation of the first driven gear and the second driven gear are parallel to each other and rotational directions of the first driven gear and the second driven gear are opposite to each other.
