6 . The robot system of claim 5 , further comprising a second robot charger configured to charge the second robot, the second robot charger being located in the station body.
7 . The robot system of claim 1 , wherein the station body includes an outlet, and
wherein the robot system further comprises:
a pusher configured to push an item located on the carrier; and
a conveyor configured to transfer the item pushed by the pusher to the outlet of the station body.
8 . The robot system of claim 1 , wherein the first robot further comprises a proximity sensor located on the first robot body.
9 . The robot system of claim 1 , wherein the first robot further comprises a guide roller located on the first robot body, the guide roller configured to roll along the station body or the second robot.
10 . The robot system of claim 1 , wherein the first robot further comprises a magnet located on a bottom of the first robot body.
11 . The robot system of claim 10 , wherein the second robot further comprises a Hall sensor configured to sense the magnet of the first robot.
12 . The robot system of claim 8 , wherein the first robot further comprises:
a battery located in the first robot body; and
a charging terminal electrically connected to the first battery.
13 . The robot system of claim 12 , wherein the lifter includes a lift plate, and wherein the charging terminal is configured to be lifted together with the lift plate.
14 . The robot system of claim 12 , wherein the second robot further comprises a supply terminal configured to be contacted by the charging terminal of the first robot.
15 . The robot system of claim 8 , wherein the lifter comprises:
a lift plate configured to lift the carrier;
a guide plate connected to the lift plate;
a lift bush located on the guide plate; and
an actuator located on the first robot body, the actuator being configured to lift the lift bush.
16 . The robot system of claim 1 , wherein the seating body of the second robot defines a first robot accommodating space configured to accommodate at least a portion of the first robot.
17 . The robot system of claim 1 , wherein the first robot comprises a wheel, and wherein a wheel accommodating portion is provided in the seating body, the wheel accommodating portion being configured to receive a portion of the wheel of the first robot.
18 . The robot system of claim 1 , wherein the second robot comprises:
a second robot body, the seating body being located on the second robot body;
a wheel connected to the second robot body;
a motor configured to rotate the wheel;
a battery located in the second robot body; and
an inner proximity sensor located on the second robot body to sense the first robot.
19 . A robot system comprising:
a station body;
a carrier located in the station body;
a first robot having a wheel and a lifter configured to lift the carrier relative to the station body, the first robot being configured to move in a first direction in the station body; and
a second robot configured to move in the station body in a second direction different from the first direction, the second robot having a seating body on which the first robot is seatable, the seating body including a wheel accommodating portion configured to receive a portion of the wheel of the first robot.
20 . A robot system comprising:
a station body;
a carrier located in the station body;
a first robot having a lifter configured to lift the carrier relative to the station body, the first robot being configured to move in a first direction in the station body; and
a second robot configured to move in the station body in a second direction different from the first direction, the second robot including:
a second robot body;
a seating body on which the first robot is seatable, the seating body being located on the second robot body;
a wheel connected to the second robot body;
