Description

[Detailed description of the invention] (Field of industrial application) The present invention focuses on the drive mechanism of the robot's eyes, and more specifically, the parts that attract attention such as the eyes and ears that protrude from the robot body (hereinafter referred to as eyes). etc.)
This invention relates to a drive mechanism for a robot's eyes, etc., which causes the eyes, etc. to reciprocate from side to side, retracts the eyes, etc. when touched by a human hand, etc., and makes the eyes, etc. come out again.

(Background of the invention) Various robots (hereinafter referred to as SP robots) have been proposed to be used for sales promotion purposes such as advertising new products.

FIG. 4 is a perspective view showing an example of the SP robot.

This SP robot includes a main body 1, a base 2 on which the main body 1 is placed, a left arm 3 extending upward from the left side of the main body 1, and a tray 4 provided at the tip of the left arm 3 on which products are placed. , a right arm 5 extending upward from the right side of the main body 1, and scissors 6 connected to the right arm 5.

The tray 4 of the left arm 3 is attached eccentrically to the left arm 3, and is rotated slowly back and forth within a range of about 90 degrees by a motor built in the left arm 3. A transparent cover 4a is removably attached to the tray 4, and a lamp for illumination is provided inside.

The scissors 6 of the right arm 5 are moved slowly up and down within a range of about 30 degrees at the elbow by a motor disposed within the elbow 6a. The scissors 6 move up and down to attract the customer's attention and make a "clicking" sound like a castanet.

This SP robot is a robot modeled after a crab, as suggested by the scissors 6 on the right arm 5, and the eyes 7 that protrude above the main body 1 are also distinctive to attract the attention of customers. Conceivable.

The creators of this case state that the eye 7 moves ``Normally, it moves left and right, but when the customer holds the eye with their hand or presses it lightly, the left and right movement stops and the eye retracts downward, and after a few seconds, the eye opens again. It is assumed that the robot will start moving from side to side. The idea was to increase the giden effect by having customers touch their eyes by sending messages, etc., and having the SP robot respond to the customer's movements and have a dialogue between the customer and the SP robot.

(Problem that the invention attempts to solve) However, in order to perform the above operation,
In the conventional way of thinking, a touch sensor was required to detect that the customer touched the eye 7, and this had to be processed to cause the eye 7 to retract. In addition, one actuator such as a motor was required to drive the eyes back and forth and up and down.

The purpose of the present invention is to perform the above-mentioned operation with a simple configuration without using a touch sensor etc.
It is an object of the present invention to provide a driving mechanism for a robot's eyes, etc., which can enhance demonstration and advertising effects.

(Means for Solving the Problems) In order to achieve the above object, the robot eye drive mechanism according to the present invention has an eye protruding from the main body. a fixed magnetic catch; a plate held by suction on the magnetic catch;
a post that is supported by the plate and has the eye attached to its tip; a flexible bush that swingably supports the post on the main body; and a drive section that provides vertical movement to the plate when the plate is removed from the magnetic catch.

(Example) The present invention will be described in detail below with reference to the drawings and the like.

1 to 3 are diagrams showing an embodiment of the driving mechanism for the robot's eyes, etc. according to the present invention.
The figure is a front sectional view, Figure 2 is a sectional view taken along line A-A in Figure 1,
FIG. 3 is a sectional view taken along the line BB in FIG. 1.

As shown in FIG. 3, a motor 11 is mounted on the machine frame 10.
A wheel 12 is attached to the output shaft of the motor 11. A shaft 12a is installed in the wheel 12 at an eccentric position of the disc. A link 13 is provided at the tip of the shaft 12a via a bearing 21.

The other end of the link 13 is connected to a shaft 15a inserted into the eye post 15 via a bearing 22, as shown in FIG. Eye post 15 is eye 7
It is a support for supporting the flexible bush 16.
It can be swung around the supported position. The eye post 15 is a cylindrical member through which wiring for illumination of the eye 7, etc. can be passed.

A link 14 is provided on the bearing 22 of the eye post 15, and this link 14 is connected to the shaft 15a of the left eye post 15, as shown in FIG.

On the other hand, a bearing 20 is provided on the shaft of the wheel 12, as shown in FIG. 3, and a notch 17a (FIG. 1) of the eye plate 17 is engaged with this bearing 20. The eye plate 17 is provided with notch grooves 17b, 17b on the left and right, and the eye posts 15, 15 are supported by these notch grooves 17b, 17b (FIG. 1). The eye plate 17 is normally connected to a magnetic catch 18 fixed to the machine frame 1.
It is held under suction.

Next, the operation of the embodiment of the robot eye structure according to the present invention will be explained.

In a normal state, since the magnetic catch 18 holds the eye plate 17, the eye 7 provided at the tip of the eye post 15 supported by the eye plate 17 protrudes from the main body 1.

When the wheel 12 rotates due to the rotation of the motor 11, the right eye post 15 is connected via the link 13.
swings left and right around the adjustable bush 16. At the same time, the left eye post 15 is connected via the link 14.
oscillates around the adjustable bushing 16.

Now, if the customer touches the eye 7, the eye plate 17 will come off the magnetic catch 18.
During this time, the wheel 12 is rotating and the shaft 12a is lowered, so the eye plate 17 is at the position shown by the two-dot chain line in FIG.
It naturally falls to the position of the bearing 20 in a. Thereafter, as the wheel 12 rotates, the bearing 20 rises and the eye 7 also rises together. Note that the shaft 12
If a is before the lowest position, the device will move down and then rise again, but this is not a problem since it is performed within the main body 1.

When the bearing 20 reaches the uppermost position, the eye plate 17 is again attracted and held by the magnetic catch 18, and the eye 7 repeats the same left and right rocking motion as described above.

Although the operation of the eye 7 has been described with reference to an example in which the left and right sides swing in the same direction, if the eye post 15 of the left eye 7 is connected to the lower side of the wheel 12 via a link in FIG. 7 and 7 can be moved closer or further away.

Furthermore, although this embodiment has been described as a driving mechanism for the eyes of a robot imitating a crab, the same can be applied to a characteristic portion protruding from the main body.
For example, it can be used for the movements of the eyes of a robot imitating a snail, the ears of a robot imitating a rabbit, the head of a robot imitating a turtle, etc.

Further, although the explanation has been given using the SP robot as an example, the present invention can also be applied to toy robots and the like.

(Effects of the invention) As explained in detail above, according to the invention,
When used in a SP robot that has a simple configuration and can drive the robot's eyes, advertising can be done in an interactive manner with the customer rather than one-sidedly, and the advertising effect can be enhanced.

Further, since an expensive touch sensor or the like is not required, and only one motor is required for driving the eyes, the robot can be manufactured at a low cost.
