Technical Field
[0001] This utility model relates to the field of robotics technology, specifically a pet companion wheeled robot. Background Technology
[0002] The development of mobile robot platforms is an important and relatively active research field. Mobile robots generally include wheeled, tracked, and legged robots. Compared to legged and tracked robots, wheeled robots operate at higher speeds and can also perform actions such as climbing stairs and crossing steps, making them more widely applicable. This quadruped robot is a biomimetic robot that mimics a domestic pet. It is a scaled-down model primarily used to study indoor human-computer interaction environments.
[0003] In recent years, many families have enjoyed keeping pets, and the number of pets has been increasing, making them a part of daily life. However, many caregivers are becoming increasingly busy with work, resulting in their pets not receiving sufficient care and companionship, which can lead to mild depression in the animals. This is especially true for clingy cats, who are prone to boredom and loneliness due to a lack of stimulation and entertainment.
[0004] Market: There are already pet companion robots on the market, but some of them have limited functions and slow movement, while others lack communication and are largely unable to interact effectively with pets.
[0005] Research on companion robots began earlier and is more mature overseas than in China. In the 1990s, companion robots gradually developed in developed countries such as the United States, the United Kingdom, and Japan. Companion robots have moved from schools and research institutions to corporate industrial research and development. Various industries have recognized the potential market and profit value of companion robots. More organized research and development is being carried out by manufacturers and professional R&D cooperation companies. In recent years, the foreign company Intuition Robotics designed a social and emotional robot called Ellit, and the American company Aeolus Robotics manufactured a two-armed humanoid robot called Aeo.
[0006] In recent years, China has also conducted research on companion robots. In 2010, a surge of research and development of hydraulically driven quadruped robots with high dynamic characteristics, large load capacity, and strong environmental adaptability emerged in China. The hydraulically driven quadruped bionic robot developed by the Robotics Research Center of Shandong University aims to design a hydraulically driven quadruped robot that can adapt to complex terrain environments and has high dynamics and high load capacity.
[0007] Even though research on quadruped robots and companion robots is being carried out in various fields both domestically and internationally, the development progress of robots specifically for pet companionship is still relatively small, so there is still much room for progress and breakthroughs in this field.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] like Figure 1As shown, the pet companion wheeled robot includes a head 1, a body 2, forearms 3, hind legs 4, and a food feeder 5.
[0035] The forearm 3 of the motion sensor can perform a ball throwing action. By adjusting the distance of the slider 10, the ball can be clamped or released. The depth camera of the eye 30 will output parameters such as position according to the target to be thrown, and change the rotation speed of the hub motor 13 to throw the ball to the target position.
[0036] like Figure 2 and Figure 3 As shown, the forearm 3 consists of two active degrees of freedom: a front shoulder joint 11 and a front knee joint 12, which allow for pitch. The front shoulder joint is driven by a front motor 7, and the front wheel is driven by a hub motor 13. The rear leg is connected by an electric push rod 14, and the rear knee joint 19 is hinged to a fixed support 18 at the rear of the body. The rear wheel 16 is connected to a three-dimensional symmetrical body 17 via a motor. The three-dimensional symmetrical body 17 is as follows: Figure 6 As shown.
[0037] The front knee joint 12 is connected to the passive telescopic joint 8, which acts as a buffer when the robot's leg contacts the ground, reducing impact and improving the robot's stability.
[0038] The small wheels 15 of the hind legs are not equipped with power and are responsible for supporting the robot to move forward after standing. When the electric push rod 14 is retracted, the small wheels 15 are lifted off the ground. When the electric push rod 14 is extended, the small wheels 15 are brought to the ground, realizing the actions of lying down, standing up, and walking on all four legs.
[0039] The front-end motor 7 is connected to the slider 10 of the electric slide rail via a right-angle fastener 9 and is fixed with screws.
[0040] One end of the slider 10 is inserted into the I-shaped slot 6, and the other end is fitted into the cylindrical slide rail to achieve horizontal movement.

It includes a chute 24, a belt 25, a food bin 26, a bottom turntable 27, and a motor 28. The motor 28 drives the belt 25 to rotate, which in turn drives the food bin 26 to rotate. The bottom turntable 27 is fixed. One-quarter of the bottom turntable 27 is hollowed out to release food. When the motor starts, the food bin 26 rotates the food inside. When it rotates to the hollowed-out part, the food falls into the chute 24 under gravity.
[0042] The grain bin 26 is divided into 4 sections, and the owner can pre-place the grain to be fed into 3 of the empty slots in the grain bin 26.
[0043] The body 2 of the grain feeder 5 is connected to the chassis and the rear legs 4 by a right-angle fastener 23.
[0044] The motor 28 has a built-in timer and angle controller. When the corresponding time is reached, the motor is started and rotates to the set angle.
[0045] The grain in the grain feeder 5 flows out through the inclined chute 24. The inclined chute is connected to the body 2 by a right-angle fastener 23 and is fixed by screws.
[0046] The connections between the four rear leg parts are all secured with pins 20.
[0047] like Figure 5 As shown, a cover 34 is provided on the top of the body 2, which is connected to the body 2 via a hinge 29. A latch is provided when lowering, and the lowest position is flush with the body 2.
[0048] The earpiece 31 installed on the head receives information to identify the pet's barks and provides feedback. The owner can also provide feedback through the mouth speaker 33, enabling remote communication with the pet.
[0049] The visual recognition system, with a depth camera installed in the eye 30, is used to identify the pet's species and position. Information acquired by the camera is fed back to the central processing unit; the high-definition projector 32 on the chest can project animations and videos.
[0050] The robot also includes an electromagnetic induction charging device 35, which is used to supply power to various electrical components in the robot.
[0051] The above embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
