When a human approach is detected, it is possible to prevent illegal intrusion or theft by preliminarily configuring such that a bark or other signal sound is produced.

  One embodiment of the present invention is characterized in that a light source is arranged in the eye (claim 3). According to this embodiment, the sense of a live dog can be obtained, and it can be used as illumination during a night walk by adjusting the brightness.

  One embodiment of the present invention is characterized in that a controller is provided at an end portion of a lead wire extending from a collar portion (claim 4). According to this embodiment, the lead wire and the so-called dog tether can be shared, which is convenient.

  One embodiment of the present invention is characterized in that a push handle that can be stowed and stowed is provided at the rear of the trunk. According to this embodiment, the traveling wheel can be set in a free state to assist walking during shopping and shopping as a so-called wheelbarrow.

    FIG. 1 is a schematic perspective view of the present invention. In the figure, reference numeral 1 denotes an inner frame made of metal, plastic or the like, and a torso 2, heads 3, and 4 that form the outer shape of a dog with plastic or the like outside through a member (not shown) with the inner frame 1 as the center. The leg 4a, 4b, 4c, 4d and the tail 5 are formed. Although not shown in detail, the outer peripheral surfaces of each of them are flocked to form a state similar to an actual dog.

  The four legs 4a, 4b, 4c and 4d are pivotally supported by pivot pins 6 on the outer side of the inner frame 1, respectively, in the illustrated embodiment. Below, an example of the walking structure by the said four legs 4a, 4b, 4c, and 4d is described.

  The reciprocating links 7a, 7b, 7c and 7d are connected to the upper ends of the four legs 4a, 4b, 4c and 4d, the intermediate portions of which are pivotally supported by the inner frame 1 by the pivot pins 6, respectively. 8 are connected.

  Further, the other ends of the reciprocating links 7a, 7b, 7c and 7d are respectively connected to the rotating pins 10 at predetermined positions of the cam plates 9a, 9b, 9c and 9d provided on the outer sides of the inner frame 1, respectively. Is done.

  Further, motors for independently controlling the cam plates 9a, 9b, 9c and 9d on the inner side of the inner frame 1 corresponding to the cam plates 9a, 9b, 9c and 9d supported on the outer side of the inner frame 1, respectively. 11a, 11b, 11c, and 11d are provided, respectively, and the whole is configured with a low load.

  Furthermore, traveling wheels 13a, 13b, 13c and 13d driven by motors 12a, 12b, 12c and 12d are provided at the lower ends of the four legs 4a, 4b, 4c and 4d.

  Further, a luggage storage portion 14 is formed on the back portion of the trunk 2. In the embodiment of the drawings, a lid 15 with a zipper is provided at the mouth of the luggage storage section 14. Further, a light source 16 such as an LED is disposed in the eye part of the head 3.

  Further, a rechargeable battery 17 is provided inside the trunk 2, and in addition, a detector 18 for detecting the approach of a person, the motors 11a, 11b, 11c and 11d, and the motors 12a, 12b, 12c and 12d, A control unit 19 such as a microcomputer for controlling the light source 16 and the detector 18 is provided.

  Further, a lead wire from the control unit 19 is guided to the collar portion 20, a lead wire 21 that also serves as a connecting string is extended from the collar portion 20, and a controller 22 is provided at the end of the lead wire 21. In the figure, reference numeral 23 denotes a hand handle provided at the rear part of the barrel 2 so as to be able to stand and retract.

  In the robot dog according to the present invention having the above-described configuration, by operating the controller 23, the motors 11a, 11b, 11c, and 11d are independently driven and controlled via the control unit 19, and the cam plates 9a, 9b, 9c are controlled. And 9d, and the four legs 4a, 4b, 4c and 4d are moved back and forth through the reciprocating links 7a, 7b, 7c and 7d in the same manner as the actual walking of the dog.

  Next, at the time of carrying the load, the four legs 4a, 4b, 4c and 4d are fixed at a stable position. Specifically, the dog is stationary, that is, the four legs 4a, 4b, 4c and 4d are fixed in an upright state, and the luggage is stored in the luggage storage unit 14.

  Thereafter, by operating the controller 23, the motors 12 a, 12 b, 12 c and 12 d are driven and controlled via the control unit 19, and traveling is performed. The running direction is controlled by individually controlling the motors 12a, 12b, 12c and 12d by the controller 23.

  As described above, the robot dog of the present invention is useful for people who have difficulty carrying luggage, and can also assist walking during shopping and shopping as a so-called wheelbarrow.
