2. The robot device according to claim 1 , wherein
the body portion includes a loading portion on which a load is placed in a space surrounded by the plurality of legs.
3. The robot device according to claim 2 , wherein
the loading portion includes a drive unit, wherein the drive unit is configured to incline a loading platform on which a load is placed to form a slope.
4. The robot device according to claim 1 , further comprising
an outer casing that covers the robot device including the plurality of legs.
5. The robot device according to claim 4 , wherein
the outer casing includes one of an openable/closable lid or a door on at least one of an upper surface of the outer casing, a front surface of the outer casing, a rear surface of the outer casing, a left side surface of the outer casing, or a right side surface of the outer casing.
6. The robot device according to claim 4 , further comprising
a frame that connects the outer casing and the body portion, wherein the frame does not interfere with a movable range of the plurality of legs.
7. The robot device according to claim 4 , wherein
one or more sensors are arranged around the plurality of legs, and
the one or more sensors includes a camera.
8. The robot device according to claim 4 , wherein
a portion of the outer casing around a toe of each of the plurality of legs is configured with one of a flexible material or an expandable component.
9. The robot device according to claim 4 , wherein
a wall surface of the outer casing is provided with a removable decoration.
10. The robot device according to claim 4 , further comprising
a sensor attached to the outer casing, wherein the sensor is configured to detect a proximate object.
11. The robot device according to claim 10 , wherein
the sensor includes one of an infrared sensor, a capacitive human detection sensor, a tactile sensor, or an air pressure sensor.
12. The robot device according to claim 10 , further comprising
a controller configured to control a safe stop or another operation of the robot device based on a detection result of the sensor.
13. The robot device according to claim 4 , further comprising
a camera inside the outer casing, wherein the outer casing includes a transmissive portion or an opening portion in a range of a field of view of the camera.
14. The robot device according to claim 4 , further comprising:
a display attached to a surface of the outer casing; and
a controller configured to control the display.
15. The robot device according to claim 14 , wherein
the controller is further configured to control display of advertisement information on the display.
16. The robot device according to claim 15 , wherein
the controller is further configured to switch the advertisement information in real time based on a current position of the robot device, a human on a spot, or sensor information.
17. The robot device according to claim 4 , wherein
the outer casing has a shape of a chair that allows a human to be seated in a space surrounded by the plurality of legs.
18. The robot device according to claim 1 , wherein
a center of gravity of the body portion is arranged below one-third of the distance between the hip joint and the knee joint of each of the plurality of legs.
19. The robot device according to claim 1 , wherein
each of the plurality of legs has a multi-link structure including the knee joint, and
the bottom surface of the body portion is arranged higher than the knee joint when a thigh link of each of the plurality of legs is in a vertically downward posture.
