Description

BACKGROUND

The present disclosure relates to an action robot, and more particularly, to an action robot including at least one joint.

As robot technology advances, a method of modularizing joints or wheels to manufacture a robot is being used. For example, various types of robots such as puppies, dinosaurs, humans, and spiders may be manufactured by electrically and mechanically connecting and assembling a plurality of actuator modules configuring a robot.

A robot capable of being manufactured by assembling a plurality of actuator modules is generally referred to as a modular robot. Each actuator module configuring a modular robot includes a motor, and thus, a motion of a robot is performed based on a rotation of the motor. Such a motion of a robot is a concept which denotes motions of a robot such as an action and dance.

Recently, robots for entertainments are attracting much attention, and thus, interest in robots for arousing the interest of persons or recreation is increasing. For example, technologies for allowing a user to dance according to music or take a motion or expression according to story (children's story and the like) are being developed.

This denotes that a plurality of motions based on music or children's story are previously set, and when the music or the children's story is reproduced by an external device, an action robot performs a motion by executing a motion previously set based thereon.

FIG. 21 is a diagram for describing an action where a pusher according to another embodiment is pressurized upward.

A configuration where a load 439 for pressurizing a pusher 194 is raised, according to the present embodiment, may differ from the above-described embodiment. Also, the present embodiment may have a feature where a motion where all of both feet 170 nod is capable of being performed. Therefore, a repetitive description is omitted, and a difference will be mainly described.

In the present embodiment, both feet 170 may move, and each of the both feet 170 may be a movable part.

The above-described driving module 400 (see FIG. 2) may include a driving source 430′ which simultaneously drive the both feet 170. The driving source 430′ may be disposed under a figure base 180 (see FIG. 2).

The driving source 430′ may raise a plurality of loads 439 which upward pressurize a plurality of pushers 194.

In more detail, the driving source 430′ may include a motor 433, a horizontal shaft 434, and a plurality of cams 435A and 435B.

The motor 433 may be disposed under the figure base 180.

The horizontal shaft 434 may be disposed long in a horizontal direction. The horizontal shaft 434 may be connected to the motor 433 to rotate.

The plurality of cams 435A and 435B may be fastened to the horizontal shaft 434. The plurality of cams 435A and 435B may be apart from each other in a horizontal direction.

The plurality of cams 435A and 435B may include a first cam 435A and a second cam 435B. A load 439 raised by the first cam 435A may upward pressurize a pusher 194 which pushes one foot 170C of the both feet 170. A load 439 raised by the second cam 435B may upward pressurize a pusher 194 which pushes the other foot 170D of the both feet 170.

The first cam 435A and the second cam 435B may raise the load 439 at different timings. That is, a fastening direction in which the first cam 435A is fastened to the horizontal shaft 434 may not match a fastening direction in which the second cam 435B is fastened to the horizontal shaft 434.

Therefore, wen some of a plurality of loads 439 are raised, the other some thereof may be lowered.

For example, when the horizontal shaft 434 rotates by 180 degrees, the first cam 435A may upward pressurize a load 439 disposed on the first cam 435A, and the second cam 435B may not pressurize a load 439 disposed on the second cam 435B. Therefore, the load 439 disposed on the second cam 435B may be lowered by an elastic force of an inner elastic member 199 (see FIG. 20). On the other hand, when the horizontal shaft 434 rotates by 360 degrees, the second cam 435B may upward pressurize the load 439 disposed on the second cam 435B, and the first cam 435A may not pressurize the load 439 disposed on the first cam 435A. Therefore, the load 439 disposed on the first cam 435A may be lowered by the elastic force of the inner elastic member 199 (see FIG. 20).

Therefore, the both feet 180 may be simultaneously driven by a single motor 433. Also, directions in which the plurality of cams 435A and 435B are fastened to the horizontal shaft 434 may be differently adjusted, and a motion where the both feet 1700 nod at different timings may be implemented.

According to an embodiment, a load raised by a lifter may pressurize a pusher embedded into a figure base, and the pusher may upward push a movable part disposed on the figure base. Also, an elastic member embedded into a figure base may apply a downward elastic force to the pusher. Accordingly, a motion where the movable part nods with respect to the figure base may be implemented.

Moreover, a pressurized part may be more adjacent to an outer perimeter of the figure base. Accordingly, a load which upward pressurizes the pressurized part may be easily disposed in a driving module so as not to interfere with another load.

Moreover, a connection part may have a height which increases in a direction from the pressurized part to a pressurizer. Accordingly, a raising operation of a load may be smoothly changed to movement of the movable part.

Moreover, a guide hole through which a pusher guide part protruding from the figure base passes may be provided in an extension portion of the connection part. Accordingly, raising or lowering of the pusher may be guided in the figure base.

Moreover, an elastic member pressuring part may be provided at an inclined portion. Accordingly, an elastic member may be sufficiently compressed between an inner upper surface of the figure base and the elastic member pressuring part.

Moreover, the elastic member may surround an outer perimeter of the elastic member supporting part. Accordingly, an elastic member supporting part may support the elastic member in a horizontal direction.

Moreover, the elastic member supporting part may pass through the elastic member pressurizing part. Accordingly, the elastic member pressurizing part may smoothly pressurize the elastic member without interfering with the elastic member supporting part.

Moreover, a load through hole through which a load passes may be provided in a lower surface of the figure base. Accordingly, the load may easily pressurize the pusher disposed in the figure base.

Moreover, a through hole through which a pressurizing part of the pusher passes may be provided in an upper surface of the figure base. Accordingly, the pressurizing part may easily pressurize the movable part disposed on the figure base.

Moreover, the figure base may include a lower plate and a base cover. Accordingly, the pusher may be easily embedded into the figure base.

Moreover, the figure may include an inner frame which is disposed in a body and is connected to the movable part. Accordingly, when an action robot is seen from an outer side, the body and the movable part may be seen like being connected to each other, and thus, an external appearance of the action robot may be enhanced.

Moreover, a connection shaft rotatably connected to the inner frame may be provided in the movable part. Accordingly, the movable part may nod with respect to the connection shaft.

Moreover, an inserting groove into which the pressurizing part of the pusher is inserted may be provided in the movable part. Accordingly, the pusher may reliably push the movable part, and moreover, a degree to which the pressurizing part of the pusher is externally exposed may be minimized.

Moreover, an inclined portion apart from an upper surface of the figure base may be provided on a lower surface of the movable part. Accordingly, the movable part may smoothly nod with respect to the upper surface of the figure base.

According to another embodiment, a plurality of cams fastened to a horizontal shaft may respectively and upward pressurize a plurality of loads, and the plurality of loads may respectively and upward pressurize a plurality of pushers. Accordingly, a plurality of movable parts may be simultaneously driven.

Moreover, the plurality of cams may be fastened to a horizontal shaft in different directions. Accordingly, the plurality of movable parts may be driven at different timings.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the spirit or scope of the disclosures. Thus, it is intended that the present disclosure covers the modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents.
