Description

Technical Field

[0001] The invention belongs to the field of robots, and in particular relates to an intelligent dog-walking robot. Background Art

[0002] Usually, walking a dog outdoors with a rope is not only a way for the dog to exercise, but also a way for the owner to enjoy the dog. Whether it is a puppy in the growing period or an old dog, it is very important to go out for activities. Going out for a walk can not only help the dog to defecate and urinate, but also exercise and strengthen the body. The ultraviolet rays in the sun can also kill bacteria and parasites on the dog. For dog walking, usually, the time and frequency of walking the dog must be regular. Twice a day, a small dog walks for ten minutes, and a medium-sized dog walks for 20-30 minutes. However, the elderly are not always in a healthy state, and they cannot go out for activities if they feel uncomfortable occasionally; for young people, they are very busy and sometimes have no time to walk the dog regularly. Therefore, puppies are prone to irritability at home, or howling loudly, which affects the lives of neighbors and is also bad for the dog's body and mind. Therefore, it is particularly necessary to develop a robot that can replace the owner to walk the dog at a critical moment to complete the task of walking the dog.

[0003] In the existing technology, dog-walking robots have some obvious shortcomings, such as insufficient intelligence, inability to conveniently replace the owner to walk the dog, inability to interact with the owner in real time, causing the puppy to sometimes become manic and restless; and easy to be dragged by the puppy or even tip over. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent dog-walking robot, which can enable the owner to walk the dog even when he is busy, not at home, or inconvenient, thereby preventing the puppy from becoming restless; the intelligent dog-walking robot can prevent dragging and tipping; in addition, it can also communicate with the puppy remotely.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent dog-walking robot, comprising a robot main unit, which includes a controller, a power supply unit and a mobile drive unit; a pull ring unit for tying a dog is arranged on the outer shell of the robot main unit; the robot main unit also includes a gravity unit for preventing rollover and a brake unit for preventing dragging; a camera unit and a broadcasting unit are arranged on the upper part of the robot main unit.

[0006] The controller of the robot main unit may include various processor chips, such as a microprocessor, a single-chip microcomputer, etc., a memory, a data reading interface, and a power supply unit; the power supply unit of the robot main unit includes a rechargeable lithium battery and a charging circuit, and the power supply unit is connected to the controller and the mobile drive unit; The robot main body unit also includes a mobile driving unit, including a motor and a driving circuit, which drives the roller to rotate and walk through gear transmission; the driving circuit has a special control unit for controlling the rotation of the motor; The controller includes digital hardware circuits such as MCU, ARM, DSP, etc. The controller is connected to the memory, data reading interface, and power supply unit; The shape of the shell can be human-shaped or conical; a ring for tying a dog is provided on it, and a sensor for detecting the magnitude of traction force is provided on the ring; the sensor obtains the magnitude of the force with which the puppy pulls the shell, and transmits the data to the controller MCU unit for processing; under normal circumstances, the force with which the puppy pulls the shell is within a preset range, and when the puppy encounters an emergency, or encounters other dogs of the same kind, it may suddenly run, at which time the force with which the puppy pulls the shell will suddenly increase, and may exceed a preset value.

[0007] The robot main body unit also includes a gravity unit, a brake and an anti-rollover unit, which are used to prevent mechanical damage caused by the dog running and pulling the robot down when walking the dog. The gravity unit has a certain mass and is placed on the chassis of the shell, so as to lower the center of gravity and prevent the humanoid robot from tipping over; at the same time, its certain mass makes the robot have a greater friction with the ground, preventing the dog from pulling the robot down when exerting too much force; in addition, when the sensor on the collar detects that the force of the dog pulling the shell is greater than a preset value, the brake device is activated at the same time to brake the moving roller to increase the friction and prevent the robot from being pulled down or rolling over by the dog.

[0008] A camera unit is arranged on the upper part of the robot main body unit, which can capture the surrounding scenes and transmit them to the owner's mobile phone or other mobile terminals. The camera can automatically capture 360-degree scenes and automatically find the position of the puppy. At the same time, the camera can also be controlled by the owner by sending commands remotely, and the captured video images are sent to the mobile phone for the owner to watch. The camera unit is composed of a VGA image sensor and its peripheral circuits. The image sensor can realize automatic detection of 50 / 60Hz, has a resolution of 640*480, and the VGA image can reach up to 30 frames / second, which meets the design requirements. After the camera collects the surrounding environment image at a fixed time, it uses the file trained by the machine learning algorithm to automatically identify the puppy in the positioning image, calculate the position of the puppy, and further adjust the camera to aim at the puppy.

[0009] A broadcasting and shouting unit is arranged on the upper part of the robot main body unit, which can play the sounds pre-recorded by the owner; for example, calling the puppy's name, issuing commands to the puppy, etc.; for example, when the sensor on the collar detects that the force of the puppy pulling the shell is greater than a preset value, it also issues a command shouting to stop the puppy from running. The broadcasting and shouting unit is composed of ready-made modules, which can recognize non-specific voices. By adding a microphone and a speaker, it can realize the collection and analysis of environmental signals. The module detects specific sounds in the environment, uploads them to the robot controller, and sends them to the owner's mobile terminal after further processing.

[0010] Furthermore, the robot also includes a positioning unit, such as a GPS unit, which can locate the position of the robot in real time; the owner can know the position of the robot in real time through a mobile phone; Furthermore, it also includes a communication unit, which can enable the puppy to communicate with the owner's mobile phone terminal; for example, the puppy's barking can be transmitted to the owner's mobile phone terminal; Furthermore, the robot also includes a path planning unit. The owner sets a route on the map and sends it to the robot, which can walk according to the set route, thereby realizing dog walking on any route. A timer can also be set, such as setting the dog walking program to automatically start at any time in the morning, noon, or evening, and reminding the owner when the time is up.

[0011] The speech recognition module is composed of ready-made modules. The module can recognize non-specific speech. By adding a microphone and a speaker, the collection and analysis of environmental signals can be realized. The module detects specific sounds in the environment, uploads them to the robot controller, and sends them to the owner's mobile terminal after further processing.

[0012] Compared with the prior art, the present invention has the following beneficial effects: through the intelligent dog-walking robot of the present invention, the owner can walk the dog even when he is busy, not at home, or inconvenient, thereby preventing the puppy from becoming restless; the intelligent dog-walking robot prevents dragging and tipping over; in addition, the owner can also communicate with the puppy remotely.
