Description

Technical Field

[0001] This utility model relates to the field of smart home and pet care technology. Specifically, it is a smart pet feeding robot equipped with Internet of Things technology and automatic execution, which can realize functions such as pet feeding, environmental monitoring, remote interaction and home security supervision in an all-round way, providing users with a one-stop smart pet care solution. Background Technology

[0002] In today's fast-paced lifestyle, office workers and frequent travelers face numerous challenges in pet care. Current pet care equipment on the market has significant shortcomings: The main drawback is the limited functionality: traditional pet feeders only offer timed and measured feeding, failing to dynamically adjust based on the pet's real-time condition and severely lacking environmental monitoring and safety supervision features. Statistics show that over 70% of pet owners expect pet care devices to have more functions to meet their pets' comprehensive needs.

[0003] The level of intelligence is seriously insufficient: most existing products lack the ability to execute autonomously, and in actual use, pet owners need to frequently intervene manually, which makes it difficult to meet users' needs for intelligent pet management.

[0004] Therefore, it is very necessary to design an intelligent pet feeding robot that integrates intelligent pet feeding, home security, and pet monitoring. Utility Model Content

[0005] This utility model aims to provide an intelligent pet feeding robot, which effectively solves the problems of limited functionality and low level of intelligence in existing pet care equipment, and realizes integrated intelligent management of pet care, environmental monitoring and home security.

[0006] The technical solution to achieve the purpose of this utility model is: A smart pet feeding robot includes an automatic pet feeding device, a storage-type robotic arm, a water tank, a storage compartment, a robot base, side rails, a motor, a motor connecting arm, Mecanum wheels, a water pipe, a battery, a camera, a network-connected host computer, a power board, a motion controller (slave computer), and an OLED display. The robot features a display screen, a voice interaction module, a smoke sensor, a temperature and humidity sensor, and a light sensor. Motor connecting arms are positioned around the bottom of the robot's base, with the motors connected to couplings on the connecting arms and Mecanum wheels mounted on them. The base contains a battery compartment for batteries and is also equipped with an automatic pet feeder, a robotic arm, a water tank, and a storage compartment. Side rails are attached to the base and closely fitted to the water tank and storage compartment. A camera is mounted on the front of the pet feeder. The storage compartment houses a power board, a motion controller (lower-level device), and a network-connected upper-level device. The exterior of the storage compartment contains the voice interaction module, smoke sensor, temperature and humidity sensor, and light sensor. OLED displays are positioned on the front of the automatic pet feeder and on the storage compartment. A water pipe extends from the water tank and connects to the robotic arm. The network-connected upper-level device, the motion controller (lower-level device), and the camera work together to form a complete and independent remote control system. Through the fusion of various sensors, the robot becomes a comprehensive environmental monitoring and home security system.

[0007] The pet feeding device includes a feeder base, a feeder action end, a turntable, a food storage compartment, a feeder top cover, and a single-axis servo motor. The single-axis servo motor is installed in a servo motor fixing groove at the bottom of the feeder action end. The turntable is installed in a turntable fixing groove at the top of the feeder action end and connected to the single-axis servo motor. The food storage compartment is installed on the top of the turntable and fastened to the feeder action end. The feeder base and the feeder top cover are fastened to the feeder action end and the food storage compartment, respectively. A camera installed in front of the pet feeding device collects data on the pet's body posture, eating status, and behavioral activities such as "filling the bowl." After analyzing the image dataset, a reasonable feeding plan is formulated for the pet. Then, a signal is sent to the motion master controller (lower device), which executes the feeding operation. The device can accurately control the feeding amount according to the different conditions of the pet, providing a more suitable food supply for the pet and thus ensuring the pet's health.

[0008] The retractable robotic arm device includes a robotic arm base, a roller, a roller flange, a roller flange cover, a flange, a flange cover, an oil seal, a bearing, a central shaft fixing component, a bottom arm, a first long arm, a second long arm, a first short arm, a second short arm, a motor, and a nozzle. The long arm measures 120mm × 50mm, the short arm measures 105mm × 50mm, the bottom arm measures 90mm × 50mm, and the nozzle measures 105mm × 50mm. The roller flange, roller flange cover, oil seal, bearing, and central shaft fixing component are respectively installed on the left side of the roller, assembling to form the roller assembly, which is then inserted into the robotic arm base. The internal double bearing houses the motor, which is located in the motor groove within the robotic arm base and connected to the central shaft fixing component. This controls the pitch angle of the robotic arm. The bottom arm has a motor for controlling the yaw angle, which is vertically installed in the groove above the roller. The first long arm is connected to the bottom arm, the second long arm is connected to the first long arm, the first short arm is connected to the second long arm, the second short arm is connected to the first short arm, and the nozzle is connected to the second short arm. All robotic arms are connected to each other through flanges, flange covers, oil seals, bearings, intermediate fixing components, and motors. The water pipe is introduced from the robotic arm base, runs from top to bottom through the nozzle, and is connected to it. This retractable robotic arm features a clever space-optimized design, allowing it to be completely stored within a compact 120mm×120mm×230mm space. This design not only significantly improves space utilization but also effectively reduces the overall size of the robot, making it more flexible and free to move around in the home, avoiding operational limitations caused by excessive size. When fully extended, the robotic arm reaches a length of 428mm and is equipped with 7 movable joints (including 6 pitch joints and 1 yaw joint). The ample extension length and flexible joint combination are sufficient to cover most pets' daily watering needs and the precise watering of potted plants in the home. It achieves a balance between "function and space," ensuring the core performance of the robotic arm while maximizing space utilization through its storage design, further enhancing operational flexibility in the home setting.

[0009] The circulating water tank device includes a water tank base, a water pump, water pipes, a water storage tank, a water storage container, a humidity sensor, and a sealing cap. The water pump is mounted in a groove on the water tank base. Two water pipes are connected to the water pump, one leading out to the robotic arm device and the other inserted into the water storage container and sealed by the sealing cap. The water storage container is installed on the water tank base, and the water storage tank is mounted on the water storage container. The humidity sensor is located on the top of the water storage tank. The entire water tank device has a capacity of approximately 5 liters. When the robot performs pet watering or plant watering tasks, the water pump is in the discharging state. When the robot performs water tank replenishment, the water pump switches to the pumping state. Once the humidity sensor on the top of the water storage tank detects that the tank is full, the water pump stops pumping. This water tank device, in cooperation with the robotic arm device, can completely complete pet watering and plant watering tasks.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The basic control system is designed to enable "active care" through autonomous movement. The unique McLaren chassis design, combined with a high-definition camera, allows the device to move omnidirectionally in complex home environments, easily avoiding obstacles and achieving comprehensive, blind-spot-free inspection and care. This fully ensures the safety and comfort of the pet's living environment while also reducing the burden on the owner.

[0011] 2. Utilizing machine vision algorithms, the robot can accurately identify a pet's feeding status, determining the appropriate amount of food based on the pet's behavior (such as licking an empty bowl), the pet's breed, and body size. Instead of feeding at fixed times, it automatically replenishes food or water. This intelligent judgment system enables the robot to perform tasks autonomously, further enhancing the user experience.

[0012] 3. The environmental monitoring and home security system is equipped not only with high-definition cameras but also with temperature and humidity sensors and smoke sensors. Users can connect to a host computer via an app to control the robot to monitor any corner of their home in real time, ensuring the safety of their pets; detecting whether the environment is suitable for pets (e.g., too hot, too cold, or too low humidity) to ensure their health. The smoke sensor can automatically alert users in the event of a fire, further enhancing home safety.

[0013] 4. The storage-type robotic arm device, with its ample extension length and flexible joint combination, is sufficient to cover most pets' daily watering needs and the precise watering of potted plants at home. It achieves a balance between "function and space," ensuring the core performance of the robotic arm while making efficient use of space through storage design, further enhancing operational flexibility in home settings.

[0014] 5. Multifunctional and integrated: It innovatively integrates multiple functions such as feeding, watering, monitoring, safety alerts, and remote interaction into one, providing users with a one-stop pet care solution. It effectively addresses users' needs in multiple scenarios during pet care and greatly enhances the user experience. Attached Figure Description

[0018] like Figure 1-6As shown, this utility model provides a novel intelligent pet feeding robot, comprising an automatic pet feeding device 2, a storage-type robotic arm device 8, a water tank device 10, a storage compartment 1, a robot base 5, robot side rails 9, a motor 42, a motor connecting arm 6, Mecanum wheels 7, a camera 3, a first OLED display screen 4, a second OLED display screen 15, a smoke sensor 14, a temperature and humidity sensor 13, a light sensor 12, a voice interaction module 11, a feeder top cover 16, a turntable 17, a single-axis servo motor 18, a feeder base 19, and a feeder operating mechanism. 20.

Second long arm 41. Water storage compartment 43. Water storage tank 44. Water tank base 45. Water pump 46. Water pipe 47. Humidity sensor 48. Sealing cover 49. Among them: The motor connecting arm 6 is fixed to the bottom of the robot base 5 around the perimeter via a preset mounting position. The motor 42 is connected to the coupling on the motor connecting arm 6, and a Mecanum wheel 7 is installed at the motor output end. A battery compartment is opened inside the robot base 5, and the battery is placed in the battery compartment and secured. Subsequently, the automatic pet feeding device 2, the storage robotic arm device 8, the water tank device 10, and the storage compartment 1 are assembled into place using the positioning structure on the base 5. The robot side guardrail 9 is fastened to the base 5 by a snap-fit ​​structure and is close to the outside of the water tank device 10 and the storage compartment 1, serving as protection and limiting function.

[0019] To assemble the automatic pet feeder 2, first, insert the single-axis servo motor 18 into the servo motor fixing groove at the bottom of the feeder's action end 20 and tighten it. Place the turntable 17 in the turntable fixing groove at the top of the feeder's action end 20 and rigidly connect it to the output shaft of the single-axis servo motor 18. Install the food storage compartment 21 on the top of the turntable 17 and seal it to the feeder's action end 20 by inserting it in. Finally, thread the feeder base 19 to the bottom of the feeder's action end 20 and fasten the feeder top cover 16 to the top of the food storage compartment 21 to complete the overall assembly of the feeding device.

[0020] The assembly steps of the storage-type robotic arm device 8 are as follows: First, install the roller flange 31, roller flange cover 32, oil seal 35, bearing 34, and central shaft fixing part 33 on the left side of the roller 36 in sequence to form a complete roller component; insert the roller component into the fixing hole inside the robotic arm base 22 to ensure smooth rotation; install the stepper motor 39 in the motor groove inside the robotic arm base 22, and connect the motor output shaft to the central shaft fixing part 33 to realize the control of the tilt angle of the robotic arm. A bottom arm 25 with a large motor 23 is vertically installed in the groove on the upper part of the roller 36. The motor is used to control the yaw angle of the robotic arm. Then, the arms are connected in the following order from bottom to top: "bottom arm 25 - first long arm 30 - second long arm 41 - first short arm 37 - second short arm 38 - nozzle 40". Each arm is connected to the small motor 27 through flange 26, oil seal 35, bearing 34, central shaft fixing part 33. Finally, the water pipe 47 is introduced from the robotic arm base 22, runs through each arm from top to bottom until it reaches the nozzle 40, and is connected to it to ensure that the water path is unobstructed.

[0021] To assemble the circulating water tank device 10, the water pump 46 is first placed on the preset groove of the water tank base 45 and fixed. Two water pipes 47 are connected to the inlet and outlet of the water pump 46 respectively. One water pipe 47 is led out to the robotic arm base 22 of the storage robotic arm device 8, and the other water pipe 47 is inserted into the water storage tank 44. The connection between the water pipe and the water storage tank 44 is sealed with a sealing cap 49 to prevent water leakage. The water storage tank 44 is installed on the water tank base 45, the water storage chamber 43 is assembled on the top of the water storage tank 44, and the humidity sensor 48 is fixed on the top of the water storage chamber 43 to ensure that it can detect the water level in the water storage chamber in real time.

[0022] The assembly of electrical components requires the installation of a power board, a motion main controller (lower-level machine), and a network-connected upper-level machine inside the storage compartment 1. These three components are connected by wires to form a control loop. A voice interaction module 11, a smoke sensor 14, a temperature and humidity sensor 13, and a light sensor 12 are installed sequentially on the outer surface of the storage compartment 1, and all of them establish a signal connection with the network-connected upper-level machine. The camera 3 is fixed to the front of the automatic pet feeding device 2 with a bracket. The first OLED display 4 is installed on the front of the automatic pet feeding device 2, and the second OLED display 15 is installed on the surface of the storage compartment 1. The camera 3, the OLED display, and the network-connected upper-level machine achieve data interaction to complete the assembly of the entire robot.

[0023] During feeding, users can establish a remote connection with a network-connected host computer via computer or mobile app to obtain real-time device status and environmental data. When performing a feeding task, camera 3 collects pet body posture data, eating status, and "empty bowl" image data, and transmits the data to the network-connected host computer. By analyzing the image dataset, the host computer analyzes the pet's species, body size, and behavioral status to formulate an appropriate feeding plan. The host computer sends a feeding signal to the slave computer, which controls the robot to adjust its position and controls the single-axis servo motor 18 in the automatic pet feeding device 2 to rotate, driving the turntable 17 to rotate. Food in the food storage bin 21 enters the feeding outlet reserved at the feeder's active end 20 through the notch on the turntable, and the food falls from the storage bin into the feeding area, achieving precise quantitative feeding.

[0024] When it is necessary to move the robot for inspection or adjust its position, the user can send a movement command through the APP, or the lower computer can control the motors 42 around the robot base 5 to operate according to the preset path. The motors drive the Mecanum wheels 7 to rotate, so as to realize the robot's omnidirectional movement. During the process, the camera 3 assists in obstacle avoidance, ensuring flexible movement in complex home environments.

[0025] When performing tasks such as watering pets or potted plants, the lower-level machine controls the water pump 46 in the water tank device 10 to start (water discharge mode), and water is delivered to the nozzle 40 of the robotic arm through the water pipe 47. At the same time, the motors of each joint of the robotic arm work together to adjust the pitch angle (controlled by the motors in the robotic arm base 22 and each long and short arm), the yaw angle (controlled by the motor in the bottom arm 25), and the extension length of each arm (120mm×50mm for the long arm, 105mm×50mm for the short arm, and 90mm×50mm for the bottom arm, with a fully extended length of 428mm) so that the nozzle 40 is aimed at the pet's water bowl or potted plant to complete the water supply. When the water level in the water storage tank 43 is insufficient, the water pump 46 switches to the pumping mode and pumps water from an external water source to the water storage tank 44. The water pump stops working after the humidity sensor detects that the water is full.

[0026] During environmental monitoring and safety early warning, temperature and humidity sensor 13 and light sensor 12 collect indoor temperature, humidity and light intensity data in real time, while smoke sensor 14 monitors for fire hazards. All data is transmitted to the user's APP via the host computer and displayed simultaneously on the OLED screen. If abnormal temperature and humidity or smoke signals are detected, the device will immediately send an alarm message to the user's APP. The voice interaction module 11 supports remote voice interaction between the user and the pet via the APP, enhancing the interactive experience.

[0027] Once all tasks are completed, the user can send a stop command via the APP, and the robotic arm will automatically retract into a compact space of 120mm×120mm×230mm, with all components returning to standby mode.

[0028] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
