Abstract

A robot includes a main body provided with a traveling unit, a body display unit disposed on an upper portion of a front side of the main body and elongated in a vertical direction, a head display unit rotatably connected to an upper portion of the body display unit, a rotary motor disposed inside the body display unit, a rotational shaft elongated in a vertical direction and rotated by the rotary motor to rotate the head display unit, and a speaker disposed inside the body display unit, spaced apart from the rotary motor, and overlapping the rotational shaft in a horizontal direction. The robot selectively receives various types of service modules to provide different services.

First claim

What is claimed is:

1. A robot comprising:
a lower housing;
one or more wheels that extend below the lower housing and rotate to move the robot;
an upper housing that extends vertically upward from the lower housing;
a head display positioned above the upper housing;
a motor provided in the upper housing;
a rotational shaft that extends in a vertical direction above the upper housing and is coupled to the head display, the rotational shaft being rotated based on a rotational force from the motor to rotate the head display; and
a speaker provided in the upper housing, the speaker being spaced apart from the motor and overlapping at least a portion of the rotational shaft in a horizontal direction,
wherein the robot further comprises:
a neck housing rotatably connected to the upper housing, wherein at least part of the rotational shaft is provided therein; and
a head housing fastened to the neck housing and spaced apart from the upper housing,

wherein the head display is received in the head housing,
wherein the rotational shaft passes through an inside of the neck housing,
wherein an opening, through which at least part of the neck housing is inserted, is formed on a top surface of the upper housing, and
wherein at least a part of the speaker overlaps the neck housing in the horizontal direction.

2. The robot according to claim 1 , wherein a vertical distance between a top surface of the upper housing and the motor is greater than a vertical distance between the top surface of the upper housing and a bottom surface of the speaker.

3. The robot according to claim 1 , wherein:
the speaker is a first speaker,
the robot further comprises a second speaker that is spaced apart from the first speaker in a horizontal direction, and
a portion of the rotational shaft is provided between the first speaker and the second speaker.

4. The robot according to claim 1 , wherein the head housing is larger than the neck housing in a horizontal direction.

5. The robot according to claim 1 , further comprising a shaft support provided inside the neck housing and configured to rotatably support the rotational shaft with respect to a horizontal plane.

6. The robot according to claim 5 , further comprising a plurality of supporting shafts extending from the shaft support through the inside of the neck housing and into the upper housing,
wherein a lower end of each of the supporting shafts is connected to a motor mount coupled to the motor.

7. The robot according to claim 6 , wherein the shaft support includes:
an annular ring through which the rotational shaft passes; and
a plurality of protrusions protruding radially outward from the annular ring and respectively connected to the plurality of supporting shafts to fix the shaft support.

8. The robot according to claim 6 , wherein at least a part of the speaker overlaps the supporting shafts in a horizontal direction.

9. The robot according to claim 5 , wherein the shaft support includes a protrusion that extends upward from an upper surface of the shaft support to limit a rotation range of the head display.

10. The robot according to claim 9 , wherein further comprising:
a shaft connecting plate provided above the shaft support and connected to the rotational shaft,
the shaft connecting plate including a locking protrusion configured to selectively interfere with the protrusion of the shaft support based on the rotation of the rotational shaft to limit the rotation range of the head display.

11. The robot according to claim 1 , wherein the head display is a first display, and
wherein the robot further comprises a second display provided in the upper housing, the second display outputting content in a horizontal direction.
