Description

Technical Field

[0001] This invention relates to the field of mobile robot technology, specifically to a multifunctional intelligent companion mobile robot. Background Technology

[0002] With the accelerating aging of the global population and the continuous growth of the elderly population, the needs for daily life monitoring and companionship for empty-nest and solitary elderly are becoming increasingly prominent. How to utilize intelligent devices to improve the quality of life for the elderly, ensure their home safety, and reduce the caregiving burden on their children and society has become an important research topic in the fields of smart home and healthcare. Currently, smart devices on the market targeting the elderly are mainly divided into two categories: wearable devices such as smart bracelets / watches, and fixed or mobile electronic devices such as smart speakers or home robots.

[0003] In the field of wearable devices, existing technologies have led to the development of smartwatches that integrate heart rate monitoring, blood oxygen monitoring, step counting, and even fall detection. For example, some products attempt to detect falls using built-in accelerometers and gyroscopes, and communicate with a mobile app via Bluetooth to send alarm messages. However, the sensors in these wristband devices typically only monitor in a resting state. For instance, when a user is sleeping or sitting still, slight hand movements or changes in the sensor's contact with the skin can cause significant data fluctuations, resulting in poor measurement stability. Furthermore, fall detection algorithms on wristband devices have a high false alarm rate, easily misinterpreting everyday actions such as sitting down quickly or waving hands violently as falls, leading to frequent false alarms that can be inconvenient for the elderly and their families. Moreover, the watch's screen and interface present an operational barrier for elderly people with declining vision and reduced finger dexterity, making many functions difficult to use effectively.

[0004] In the realm of smart speakers and robots, existing products such as smart speakers already possess functions like voice interaction, music playback, and weather inquiries. Some high-end models have begun integrating simple infrared sensors or cameras, attempting to perform security monitoring. However, the functions of these devices are relatively isolated, primarily limited to voice entertainment and basic information retrieval, lacking the monitoring capabilities deeply integrated with the user's physiological health status. Furthermore, the interaction design of existing robots often neglects the physiological characteristics of the elderly, with issues such as excessively small buttons, complex interfaces, and difficulty in movement being common, resulting in high learning costs and low willingness to use them among the elderly.

[0005] More importantly, in existing technological solutions, wearable devices and fixed / mobile smart home devices are often disconnected. Watch data can only be viewed on a mobile phone, while speakers cannot access the watch's real-time monitoring results. When an elderly person falls or experiences an abnormal heart rate, the watch can issue an alarm, but if the elderly person does not have a mobile phone with them or is unconscious, the faint beeping or vibration is unlikely to attract attention, significantly reducing the alarm's effectiveness. Conversely, while smart speakers have larger speakers and more prominent interfaces, they lack physiological data input and cannot proactively identify whether an elderly person is in danger. Therefore, we propose a multifunctional intelligent companion mobile robot. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional intelligent companion mobile robot to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional intelligent companion mobile robot, comprising a robot body, the robot body comprising a body, a scratch-resistant plastic cover, a base, and a wearable monitoring watch, wherein a main control chip is disposed inside the body, the top of the body is connected to the scratch-resistant plastic cover, and a display screen is disposed inside the scratch-resistant plastic cover, the display screen being configured to display a variety of anthropomorphic expressions, and the surface of the body having an arc-shaped touch interaction area, and the surface of the touch interaction area having an ambient light strip;

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 and Figure 2The present invention provides a technical solution: a multifunctional intelligent companion mobile robot, including a robot body 16, the robot body 16 including a body 1, a scratch-resistant plastic cover 2, a base 6 and a wearable monitoring watch 9, a main control chip 13 is provided inside the body 1, the top of the body 1 is connected to the scratch-resistant plastic cover 2, and a display screen 3 is provided inside the scratch-resistant plastic cover 2. The display screen 3 is configured to display a variety of anthropomorphic expressions. The surface of the body 1 is provided with a curved touch interaction area 4, and the surface of the touch interaction area 4 is provided with an ambient light strip 5.

[0030] The bottom of the device 1 is fixed to a base 6, and the bottom of the base 6 is provided with multiple wheels 7. The device 1 is externally connected to a wearable monitoring watch 9, which integrates an accelerometer 10 and a gyroscope 11. The accelerometer 10 and the gyroscope 11 are used to collect the user's motion and physiological data.

[0031] It should be noted that in this embodiment, the body 1 is the main frame of the entire robot, made of high-strength lightweight plastic, and houses core electronic components such as the main control chip 13, speaker, power module, and communication module. A scratch-resistant plastic cover 2 is connected to the top of the body 1. This cover is made of a translucent, scratch-resistant plastic material, similar to that used in mobile phone screens, offering good light transmission and touch sensitivity, and is not easily scratched. The scratch-resistant plastic cover 2 is hemispherical in shape, with frosted or rounded edges, smooth and burr-free, preventing scratches to the user and reducing dust accumulation for easy cleaning. A display screen 3 is installed inside the scratch-resistant plastic cover 2. This display screen 3 is electrically connected to the main control chip 13 and is configured to display various anthropomorphic expressions, such as smiling, blinking, and surprise, giving the robot a friendly "cute big head" appearance and reducing the sense of distance for elderly people towards technological products.

[0032] A curved touch interaction area 4 is located on the central surface of the robot body 1. This area is a capacitive touch panel, allowing users to operate it with gestures such as tapping and swiping, just like operating a smartphone. An ambient light strip 5, consisting of multi-color LEDs, is located at the bottom of the touch interaction area 4 and is connected to the main control chip 13 to indicate the robot's current working status. For example, a blue breathing light indicates charging, a solid green light or a flowing light effect indicates normal operation, and a flashing red light indicates a malfunction or warning, allowing users to intuitively perceive the device's status.

[0033] The robot body 1 is fixedly connected to a base 6, also known as "flexible little feet". The base 6 is made of sturdy and durable engineering plastic with an antibacterial coating to maintain hygiene. Multiple wheels 7 are evenly installed on the bottom of the base 6, preferably omnidirectional wheels or Mecanum wheels, and equipped with independent shock-absorbing and noise-reducing motors, enabling the robot to move smoothly and quietly on various home floor surfaces such as tiles, wood floors, and carpets, adapting to the home environment of the elderly.

[0034] The robot body 1 is externally connected to a wearable monitoring watch 9. The wearable monitoring watch 9 is detached from the robot body 16 and worn by the user on their wrist. The wearable monitoring watch 9 integrates an accelerometer 10 and a gyroscope 11 as motion sensors to collect the user's motion data in real time, including steps, posture, movement trajectory, and sudden impacts. The wearable monitoring watch 9 maintains a wireless signal connection with the main control chip 13 via Bluetooth 5.0 protocol, enabling real-time data synchronization.

[0035] Please see Figure 2 The wearable monitoring watch 9 also integrates an optical heart rate and blood oxygen sensor 12. The optical heart rate and blood oxygen sensor 12 is built into the skin contact surface of the wearable monitoring watch 9 and fits against the user's wrist skin to collect photoplethysmography (PPG) signals when the user is wearing the watch.

[0036] It should be noted that in this embodiment, the wearable monitoring watch 9 can also be equipped with a 2-pin Pogo Pin charging contact at the bottom, supporting 5V / 1A wired fast charging to meet emergency power replenishment needs, and has built-in overvoltage / overcurrent protection. In use, the user wears the wearable monitoring watch 9 on their wrist, and the watch automatically powers on and establishes a low-power wireless connection with the main control chip 13 inside the robot body 16 via Bluetooth 5.0. After the connection is established, the wearable monitoring watch 9 and the robot form a distributed sensing network: the wearable monitoring watch 9 is responsible for collecting the user's physiological and motion data close to the body, while the robot is responsible for energy replenishment, deep data processing, human-computer interaction, and external communication.

[0037] Please see Figure 1 and Figure 2 The main control chip 13 adopts a Bluetooth audio SoC chip that integrates Bluetooth communication and DSP digital signal processing functions. The Bluetooth audio SoC chip is configured to simultaneously handle lightweight computation of audio decoding and health data from the watch.

[0038] It should be noted that in this embodiment, the main control chip 13 is the core of the robot's computation. It is a Bluetooth audio SoC chip that integrates Bluetooth communication and DSP digital signal processing functions, such as the Hengxuan BES2500 series or the Jerry AC698N series. This chip has a CPU clock speed of ≥300MHz and a built-in DSP module that supports 32-bit floating-point operations. This selection allows the same chip to simultaneously and efficiently handle audio decoding tasks (such as playing MP3 music and processing voice interaction) and lightweight computations of health data from the wearable monitoring watch 9 (such as real-time filtering of heart rate signals and noise interference cancellation), reducing the number of onboard components, lowering power consumption, and improving data processing accuracy.

[0039] Please see Figure 1 A camera and microphone are installed on the outside of the device body 1, and electronic components are housed inside the device body 1. A mounting slot is provided on the outside of the device body 1, and a charging base 8 adapted to the wearable monitoring watch 9 is provided in the mounting slot. The charging base 8 is configured to provide power to the wearable monitoring watch 9 and establish a data communication connection when the wearable monitoring watch 9 is placed on it. The wearable monitoring watch 9 is connected to the main control chip 13.

[0040] It should be noted that, in this embodiment, in order to facilitate the storage and charging of the watch, an installation slot is provided on the outer side (e.g., the front or top) of the body 1. A charging base 8 adapted to the wearable monitoring watch 9 is provided in the installation slot. The charging base 8 is preferably a positioning slot type wireless charging base. The positioning slot depth is ≥5mm, and the diameter of the positioning slot matches the dial diameter of the wearable monitoring watch 9, with the error controlled within ±2mm. This ensures that the elderly can simply "put the watch into the positioning slot" to automatically align with the charging coil without deliberate alignment. The surface of the positioning slot is treated with anti-slip silicone to prevent the watch from slipping. The charging base 8 is configured to provide wireless charging power to the wearable monitoring watch 9 when it is placed on it, and at the same time establish a data communication connection (such as an enhanced link through NFC or Bluetooth pairing), so that the robot body 16 can read the health data stored in the watch, or share the network connectivity of the robot body 16 with the watch.

[0041] Please see Figure 3 The outer side of the body 1 is provided with a groove 14, and a metal handle 15 is rotatably disposed in the groove 14. The metal handle 15 is fitted inside the groove 14.

[0042] It should be noted that in this embodiment, the groove 14 is designed to hide the metal handle 15, keeping the appearance of the body 1 simple. When it is necessary to move the robot or lift it, the user can pull the metal handle 15 out of the groove 14 for easy application of force.

[0043] Please see Figure 1The robot body 16 is configured as follows:

[0044] In response to the watch detecting a violent impact that may indicate a fall, the robot body 16 issues a voice inquiry through its speaker; if no user response is detected within a preset time or if the user confirms that they need help, the robot automatically dials a preset emergency contact number or sends an alarm SMS containing location information.

[0045] It should be noted that in this embodiment, when the user wears the wearable monitoring watch 9, the built-in accelerometer 10 and gyroscope 11 continuously monitor the user's posture changes. If a severe impact suspected of causing a fall is detected (e.g., acceleration change rate ≥ 800mg), the main control chip 13 receives a trigger signal via Bluetooth and then controls the speaker of the robot body 16 to loudly ask, "Are you alright? Do you need help?" If no response is detected from the user via the watch, voice, or touch interaction area 4 within a preset time (e.g., 30 seconds), or if the user confirms the need for help through a specific gesture or voice, the robot body 16 will automatically dial a preset emergency contact number via the built-in Wi-Fi or 4G communication module and send an alarm SMS containing GPS location information.

[0046] Please see Figure 1 The robot body 16 is configured as follows:

[0047] When the wearable monitoring watch 9 is placed on the charging dock 8, the optical heart rate and blood oxygen sensor 12 is automatically activated to obtain the user's heart rate data in a resting state; when the monitored heart rate data exceeds the preset threshold, a voice reminder is issued through the speaker of the robot body 16.

[0048] It should be noted that in this embodiment, when the user rests at night or sits quietly during the day, the wearable monitoring watch 9 is placed on the charging base 8 of the robot body 16. At this time, the robot body 16 is configured to automatically activate the high-precision continuous monitoring mode of the optical heart rate and blood oxygen sensor 12 to obtain the user's heart rate data in a resting state. When the main control chip 13 analyzes and detects the heart rate data and it continuously exceeds a preset threshold (e.g., the resting heart rate is continuously higher than 100 beats / minute), a gentle voice reminder is issued through the speaker of the robot body 16: "Your heart rate is a little high, please take a rest," or the user can be remotely notified to their children via an APP.

[0049] While the user places the wearable monitoring watch 9 on the charging dock 8 to charge at night, the optical heart rate and blood oxygen sensor 12 and the accelerometer 10 work together to synchronously monitor sleep throughout the night, recording heart rate variability, blood oxygen changes, respiratory rate, and body movement frequency. Based on this data, the main control chip 13 generates a detailed sleep report (duration of deep sleep or light sleep, number of awakenings, etc.), which can be pushed to the user and their children via the APP.

[0050] Please see Figure 1 and Figure 2 It also includes a communication module that connects to a remote APP control terminal. The robot body 16 is configured as follows:

[0051] Receive and play voice messages or on-demand audio from the remote APP control terminal; send health data collected by the watch to the remote APP control terminal, including at least one of real-time heart rate, steps, and sleep reports; respond to the electronic fence set by the remote APP control terminal, and send an alarm notification to the remote APP control terminal when the wearable monitoring watch 9 is detected to leave the preset safe area.

[0052] It should be noted that, in this embodiment, after the children install the corresponding APP on their own mobile phones and bind it to the elderly person's robot, the following functions can be achieved:

[0053] ① Remote playback and message leaving: Children can select songs or record voice messages through the APP. The robot body 16 receives the messages and plays them directly, and reminds the elderly with a voice message, "There is a message from your children."

[0054] ②Health data viewing: Children can open the APP to view the elderly's real-time heart rate, steps, sleep reports and other health data, as well as data trend charts at any time;

[0055] ③ Electronic Fence: Children can set a safe zone in the APP (e.g., a radius of 500 meters centered on the home). When the wearable monitoring watch 9 detects that the user has left this area, the robot body 16 sends an alarm notification to the children's APP via the communication module: "Mom and Dad have left the safe zone", promptly reminding the children to pay attention to the elderly's whereabouts.

[0056] Children can pre-set medication times via an app (e.g., "take blood pressure medication at 8 AM every day"). At the set time, the main control chip 13 controls the robot 16 to automatically move to the area where the elderly person frequently stays (e.g., the living room) and announce in a gentle voice, "Grandpa, it's time to take your blood pressure medication." If the camera or sensors detect that the elderly person has not taken the medication, a reminder can be sent again after 5 minutes, along with a confirmation message to the children.

[0057] Working principle: When the robot body 16 is powered on, the main control chip 13 loads the preset age-friendly interactive interface, controls the display screen 3 to display the default anthropomorphic expression (such as a smile), and at the same time displays a solid green light through the ambient light strip 5 to indicate that the device is in normal working condition. The walking wheels 7 are in standby mode, and the robot can either be left to charge or perform timed inspections indoors according to preset logic;

[0058] The user wears the wearable monitoring watch 9 on their wrist. The watch automatically powers on and establishes a low-power wireless connection with the main control chip 13 inside the robot body 16 via Bluetooth 5.0. After the connection is established, the watch and the robot form a distributed sensing network: the wearable monitoring watch 9 is responsible for collecting the user's physiological and motion data close to the body, while the robot is responsible for energy replenishment, in-depth data processing, human-computer interaction, and external communication.

[0059] When a user wears the wearable monitoring watch 9 during daily activities (such as walking, sitting, and lying down), the built-in accelerometer 10 and gyroscope 11 continuously collect triaxial acceleration and angular velocity data at a default frequency (such as 1Hz). This raw data is initially filtered by the microprocessor inside the wearable monitoring watch 9 and then transmitted in real-time to the main control chip 13 of the robot body 16 via Bluetooth GATT protocol. The optical heart rate and blood oxygen sensor 12 emits beams of light of specific wavelengths (usually red and infrared light) to irradiate the skin and receives changes in light intensity after reflection or transmission through the blood vessel bed. Because blood volume changes periodically with heartbeats, its absorption of light also changes accordingly, thus forming a pulse wave signal. The collected raw photoplethysmography pulse wave signal is then transmitted to the main control chip 13 via Bluetooth.

[0060] The main control chip 13, as the core processing unit, adopts a Bluetooth audio SoC with integrated DSP (Digital Signal Processing) functionality. The DSP module first performs a motion artifact elimination algorithm on the received raw physiological signals. Since users generate interference noise during activity, the DSP uses synchronously received data from the accelerometer 10 and gyroscope 11 as a reference. Through an adaptive filtering algorithm, it removes noise components caused by limb movement from the photoelectric signals, extracting a pure pulse wave signal, and then accurately calculates the heart rate and blood oxygen saturation. The main control chip 13 continuously analyzes the fused data from the accelerometer 10 and gyroscope 11. Through a preset posture calculation algorithm, it identifies the user's current state (still, walking, lying down). Specifically, considering the behavioral characteristics of the elderly, the algorithm is set to "continuous stillness ≥ 90 minutes" as a sedentary state, triggering a sedentary reminder logic. When an instantaneous acceleration change rate ≥ 800mg is detected accompanied by a specific angular flip change, it is initially judged as "suspected fall." The main control chip 13 detects in real time whether the wearable monitoring watch 9 has been placed in the charging base 8 through the contact status of the charging base 8 or the wireless charging communication protocol. When the watch is detected to be placed in the charging dock 8, the main control chip 13 determines that the user has entered a resting or sleep state, and then sends a command to the wearable monitoring watch 9 to automatically increase the sampling frequency of the optical heart rate and blood oxygen sensor 12 from the default low-power mode (e.g., 1Hz) to a high-precision mode (e.g., 5Hz or continuous wave mode), thus initiating continuous and accurate resting heart rate monitoring. At this time, because the arm is relatively still, the measured physiological data has higher clinical reference value.

[0061] When the algorithm determines that a "fall" event has occurred, the main control chip 13 immediately interrupts the current task and controls the robot body 16 to emit a high-decibel voice inquiry through the speaker: "Are you alright? Do you need help?" Simultaneously, it may move the robot closer to the user for observation. The main control chip 13 starts a timer, waiting for the user's response. The user can provide feedback through voice (such as saying "Need help" or "I'm fine"), touch interaction area 4, or waving. If no valid response is detected within a preset time, the main control chip 13 determines it as a serious event and immediately initiates an emergency contact process through the built-in 4G / Wi-Fi communication module: dialing preset emergency contact numbers sequentially, playing a pre-recorded help request voice; and simultaneously sending an alarm SMS containing real-time GPS location (provided by the robot body 16's positioning module) to all emergency contacts.

[0062] In resting monitoring mode, if the heart rate data analyzed by the main control chip 13 continuously exceeds the preset threshold (e.g., continuously higher than 100 beats / min or lower than 40 beats / min), or the blood oxygen saturation is lower than the safe value (e.g., 94%), the chip triggers a health warning logic. The control robot 16 moves to the user's side and emits a gentle voice reminder through the speaker, such as "Your heart rate is a little fast, please rest" or "Your blood oxygen is low, we suggest deep breathing." Simultaneously, the abnormal data is pushed to the child's remote APP via the communication module; when the remote APP control terminal sends a voice message or plays a song, the communication module receives the data and forwards it to the main control chip 13. After decoding the audio file, the chip plays it through the speaker and simultaneously controls the display screen 3 to show a listening expression, while the ambient light strip 5 presents a warm, flowing light effect. At the same time, the main control chip 13 packages the received health data (heart rate, steps, sleep report) and uploads it to the cloud via encrypted communication for the remote APP to access at any time.

[0063] When the user places the watch into the charging dock 8, the wireless charging transmitting coil of the robot body 16 and the receiving coil inside the wearable monitoring watch 9 are coupled through electromagnetic induction to achieve contactless power transfer. The communication coil built into the charging dock 8 also interacts with the watch, reporting the charging status and transmitting data. When executing the "return to base" command or needing to approach the user for reminders, the main control chip 13 drives the motor of the walking wheel 7 to rotate. Combined with the built-in obstacle avoidance sensors, the robot can plan a path, navigate autonomously in the indoor environment, move to a designated location, or follow the user.

[0064] In summary, this invention uses a wearable monitoring watch 9 to collect data close to the body, and utilizes the robot body 16 as a data processing center, energy supply station, and powerful interactive execution terminal to achieve seamless connection from physiological signal perception, intelligent analysis and decision-making to execution in the physical world, thus constructing an all-weather, proactive, and humanized intelligent companionship and safety protection system.
