This description generally relates to robots, and specifically to assistant robots.
Human companionship is necessary for everyone's physical and mental well being. A reliable and responsible companion that caters to one's needs, provides support, helps with house chores, interacts with people, and fulfills many other social functions is costly and difficult to find. With the drastic advancement in technology areas, home assistants have been becoming more popular. However, conventional home assistants are limited in their capabilities. For example, smart speakers are only able to answer queries and commands, and robot vacuum cleaners are only able to clean floors.
Described herein are assistant robots that observe signs of core health, health dangers, and/or signs of medical distress in a home, at work, in a health care facility, or other institutions. As such, the assistant robots can take actions to prevent dangerous situations, diagnose health problems, respond to requests for help, and provide regular treatments or analysis of a person's medical state.
The assistant robots can learn users' habits or be provided with knowledge regarding humans in its environment. The assistant robots develop a schedule and contextual understanding of the persons' behavior and needs. The assistant robots may interact, understand, and communicate with people before, during, or after providing assistance. Examples of observational recognition can include body language, human interaction with recognized objects, routines over time, and human motions. The robot can combine gesture, clothing, emotional aspect, time, pose recognition, action recognition, and other observational data to understand people's medical condition, current activity, and future intended activities and intents.

The user interface 202 interfaces with a user 201. The user interface 202 receives user commands and presents information such as further inquiries, responses, recommended actions, etc. In some embodiments, the user interface 202 includes a voice user interface that permits the user 201 to interact with the assistant robot 102 verbally. The user interface 202 receives voice inputs from the sensor system 210 (e.g., a sound sensor 216) and processes the voice inputs to recognize a command or a request included in the voice inputs. The user interface 202 synthesizes information into speech and outputs the speech to the user 201. The user interface 202 may also include a graphic user interface that receives inputs from I/O devices (e.g., a keyboard, a mouse, a touch pad) or from the client device 110 and provides articulated graphical output on a display. The user interface 202 may include a gesture user interface that receives gesture inputs from the sensor system 210 (e.g., an image sensor 212) and processes the gesture inputs to recognize a command or a request in the gesture inputs. The user interface 202 may include other types of user interfaces.
The sensor system 210 includes sensors that collectively generate data about the user, the surrounding environment of the robot 210, as well as the robot 102. The sensor system 210 includes an image sensor 212 that captures images of the user 201. The images can be two dimensional (2D) or three-dimensional (3D) images. The images can be monochrome or multi-color. The images can be generated by visible light of which the wavelengths are in the range of 400-700 nm or invisible light of which is wavelengths are outside the 400-700 nm range. The sensor system 210 includes a position sensor 214 that measures a position and/or motion of the robot 210. Example position sensors 214 include an accelerometer that measures translational motion (forward/back, up/down, left/right), a gyroscope that measures rotational motion (e.g., pitch, yaw, roll), a magnetometer that measures the earth's magnetic field at the robot's 102 location, a geographical location sensor that measures a location of the robot's 102, or another suitable type of sensor that detects motion. The position sensor 214 may be a part of an inertial measurement unit (IMU) that measures one or more of force, angular rate, and magnetic field surrounding the robot 102. The IMU determines position data of the robot 102 based on measurements generated by the position sensor 214 and/or the depth information generated by the depth sensor 216.
The sensor system 210 includes a depth sensor 216 that measures depth information of objects such as the user 201 in the surrounding environment. The depth information includes the distance and relative location. The depth sensor 216 may be an ultrasonic sensor that captures ultrasound images, a time-of-flight (ToF) camera, or a Lidar. The sensor system 210 includes a microphone 217 that captures sound waves in the surrounding environment.
The sensor system 210 may include other sensors 218. The other sensors 218 may include a pressure sensor to sense an amount of pressure exerted by the robot 102, a touch sensor to detect the contact between the robot 102 and another object such as the user 201, an array microphone to capture sound and source direction in the surrounding environment, a barometer to capture atmospheric pressure in the surrounding environment, and a thermometer to measure an ambient temperature of the surrounding environment or a temperature of another object such as the user 201. The other sensors 218 may further include a hygrometer that measures the humidity in the surrounding environment, and a gas detector that measures a gas concentration in the surrounding environment. The other sensors 218 may include electrodes that measure physiological data of the user 201 such as electromyography (EMG) signals also referred to as muscle data, electrocardiograph (ECG) signals also referred to as heart rate data, electroencephalograph (EEG) signals, magnetoencephalography (MEG) signals, among other types of signals. The other sensors 216 may include other types of sensors.
The sensors of the sensor system 210 may be integrated in the housing that encloses the components of the robot 102 or be separate from the physical body of the robot 102. For example, a sensor may be attached to the user 201 or be placed in the environment. The sensor system 210 provides the captured information to the user interface 202 or the control system 220 for further processing.
The control system 220 controls the robot 102. For example, the control system 220 determines actions for the robot 102 to perform. Example actions include following the user 201, monitoring the user's 201 actions, recognizing the user's 201 command and responding to the recognized command, determining the user's 201 health condition and responding to the determined health condition, determining the user's 201 intent and responding to the determined intent. The control system 220 determines the user's 201 health condition by using the sensor data generated by the sensor system 210. The control system 220 determines the user's 201 intent by using the sensor data generated by the sensor system 210. In various embodiments, the control system 220 aggregates and analyzes the sensor data from the sensors.
As illustrated, the control system 220 includes a data processing module 221, a health module 222, an intent module 224, a response determination module 226, a motion controller 228, a sensor data store 229, a user data store 230, a health data store 231, an intent data store 232, and a model data store 233. Some embodiments of the control system 220 have different modules than those described here. Similarly, the functions can be distributed among the modules in a different manner that is described here.
The data processing module 221 processes raw sensor data stored in the sensor data store 229. For example, the data processing module 222 may process images to recognize an action (e.g., walking, sitting, holding an object, opening a door, petting a dog, reaching for an object, etc.), a gesture (e.g., right hand wave, left hand wave, head nod, twist arm, etc.), a body part (e.g., a face, a hand, an arm etc.) a facial expression (e.g., smile, frown, cry, surprised, agitated, etc.), a body position (e.g., standing on both legs, standing on left leg, standing on right leg, supine, prone, right lateral recumbent, left lateral recumbent, etc.), a physical appearance (e.g., a skin condition such as rash, a droopy face, a piece of clothing, etc.), an object (e.g., a cup, a dog, a cat, a suitcase, a key, etc.) The health module 222 may process sound signals to recognize spoken content (e.g., a word, a phrase, a request, and the like), a speech characteristic (e.g., a pitch, a volume, a speed, etc.), and the like. As another example, the health module 222 may determine temporal information (e.g., a starting time, an end time, a time duration, etc.) and/or locational information (e.g., a geographic location, a zone in a building (e.g., living room, bedroom, kitchen, bathroom, basement, stairway, office, etc.), a relative position with an object, etc.) of an action, a gesture, a face, a facial expression, spoken content (e.g., a word, a phrase, a request, and the like), a speech characteristic (e.g., a pitch, a volume, a speed, etc.), and the like. As a further example, the health module 222 determines a temporal characteristic (e.g., a rate during a time interval, a time period, etc.) of a particular action, gesture, facial expression, spoken content, and the like. The time interval and the time period may be configured by the user 201 or by an administrator according to a recommended guideline. The time interval and the time period may be varied.
The data processing module 221 may determine a routine of the user 201 such as the user's 201 typical sleeping hours and other habits, and a daily time distribution of the user's 201 location. The data processing module 221 may employ one or more data processing algorithms, classifiers, artificial intelligence models, machine learning models stored in the model data store 237 to process the sensor data as described above.
The health module 222 determines the user's 201 health condition. The health condition includes a likelihood of the user 201 being healthy, unhealthy, injured, or subject to a health threat. The health module 222 may further diagnose a type of medical condition. Example medical conditions include fever, breath shortness, digestive problems, dehydration, stroke, and the like. The health module 222 determines the health condition using the raw sensor data generated by the sensor system 210 and/or processed data output by the data processing module 221. The health condition may be additionally determined by the user data stored in the user data store 230.
The health module 222 can detect that the user 201 may have a potential health problem based on the sensor data indicating that the user 201 acts irregularly. That is, if the user's 201 behavior deviates from the normal behavior. The normal behavior can be general normal behavior determined from data about the general population or specific normal behavior determined from data about the user's 201 historical behavior. The health module 222 may further diagnose the user's 201 specific health condition by comparing the user's 201 behavior to categorized known conditions. For example, if the sensor data indicates that the user is asleep (or unconscious) in a new and unusual location (e.g., hallway) and the user 201 normally sleeps in one location (e.g., in the bedroom), the health module 222 determines that the user 201 may have fainted. If the sensor data indicates that the user opens windows too often, the health module 222 determines that the user 201 may have a shortness of breath. If the sensor data indicates that the user 201 goes to the bathroom more often than usual, the health module 222 determines that the user 201 may have digestive problems or kidney disease. If the sensor data indicates that the user 201 is asleep (or unconscious) longer than usual, the health module 222 determines that the user 201 may have a fever, inflammation, anemia, hypothyroidism, or heart disease. If the sensor data indicates that the user 201 has a higher than normal body temperature, the health module 222 determines that the user 201 may have a fever or inflammation. If the sensor data indicates that the user 201 coughs, the health module 222 determines that the user 201 may have caught a cold. If the sensor data indicates that the user 201 wanders around at night during sleeping hours, the health module 222 determines that the user 201 may be sleepwalking. If the sensor data indicates that the user 201 sets the air conditioner temperature to a higher than normal temperature regularly, the health module 222 determines that the user 201 may have problems with the blood circulatory system. If the sensor data indicates that the user 201 forgets about activities typically performed, the health module 222 determines that the user 201 may have dementia. If the sensor data indicates that the user 201 blows the nose, the health module 222 determines that the user 201 may have caught a cold or an allergy.
The health module 222 can detect that the user 201 may be injured based on the sensor data indicating that the user 201 acts unexpectedly. The health module 222 may further diagnose the user's 201 specific health condition by comparing the user's 201 behavior to categorized known conditions. If the sensor data indicates that the user 201 screams and falls down, the health module 222 determines that the user 201 may have suffered an ankle sprain or head injury. If the sensor data indicates that the user 201 has a shortness of breath and notices that the person faints, the health module 222 determines that the user 201 may have suffered a heart rhythm disorder. If the sensor data indicates that the user 201 has a change in speech habits or face asymmetry, the health module 222 determines that the user 201 may have suffered a stroke. If the sensor data indicates that the user 201 has jaundice, the health module 222 determines that the user 201 may have a kidney disease or hepatitis.
The health module 222 can detect that the user 201 may be at a health risk based on the sensor data indicating that the environment is unsafe. If the sensor data indicates that carbon monoxide is building up or there is rot or mold, the health module 222 determines that the environment is not safe for the user 201.
The health module 222 may provide the sensor data to one or more machine learning models to determine the health condition. The machine learning models include one or more artificial intelligence models, classifiers (e.g., logistic classifiers, support vector machines, and multi-class classification), decision trees, neural networks, deep learning models, or any combination thereof. The machine learning models include correlations between the health condition and sensor data. The sensor data include physical condition features, mental condition features, behavior features, environment features, and the like. In some embodiments, the machine learning models include correlations between one or more features included in the sensor data and the health condition. For example, model parameters of a logistic classifier include the coefficients of the logistic function that correspond to different features included in the sensor data.
As another example, the machine learning models include a decision tree model, which is a directed acyclic graph where nodes correspond to conditional tests for a feature included in the sensor data and leaves correspond to classification outcomes (i.e., presence or absence of one or more features). The parameters of the example decision tree include (1) an adjacency matrix describing the connections between nodes and leaves of the decision tree; (2) node parameters indicating a compared feature, a comparison threshold, and a type of comparison (e.g., greater than, equal to, less than) for a node; and/or (3) leaf parameters indicating which health condition correspond to which leaves of the decision tree.
The health module 222 creates machine learning models (e.g., determines the model parameters) by using training data. The training data includes a set of raw or analyzed sensor data labeled with features. For example, the training data are sensor data for which features have already been identified (e.g., by the health module 222, by the user 201, by an administrator, by an expert, or a combination thereof). The health module 222 determines the model parameters that predict the health conditions associated with the sensor data. For example, the health module 222 determines an objective function indicating the degree to which the determined health conditions matching the health conditions indicated in the training data. The health module 222 modifies the parameters to optimize the objective function, thereby reducing differences between predicted health conditions and actual health conditions.
One example of labeled training data is illustrated in
The health module 222 further updates machine learning models (e.g., model parameters of the machine learning models) using information received, for example, via the user interface 202 and/or the sensor system 210. For example, after the robot 102 determines a health condition based on the sensor data, the robot 102 confirms with the user 201 on the health condition. The user's 201 positive feedback (e.g., confirmation) indicates that the machine learning models are accurate and negative feedback (e.g., disapproval) indicates that the machine learning models need to be improved.
The intent module 224 determines the user's intent. The intent described herein includes the user's intention or plan to complete a task, need for a task to be complete, or a regularly-performed task that should be complete. The intent module 224 determines the intent using the raw sensor data generated by the sensor system 210 and/or processed data output by the data processing module 221. The intent may be determined by further using the user data stored in the user data store 230 and/or querying the internet.
The intent module 224 can determine the user's intent by recognizing a current activity that the user 201 is undertaking, the user's 201 routine, and contextual information. As one example, the intent module 224 determines that the user 201 intends to perform an action on an object (e.g., have a water bottle, pick up a box, carry a dish, etc.) if the user 201 points at an object. The intent module 224 determines that the user is likely to have a coffee and take a shower if the user 201 is waking up in the morning. The intent module 224 determines that the user 201 is getting ready for bed and will intend to lock doors if the user 201 starts to brush teeth at night. The intent module 224 determines that the user 201 is going to work and will need the laptop if the user 201 has had breakfast and is putting on work clothes. The intent module 224 determines that the user is likely to be home soon and turns on the air conditioner if the time is approaching the user's regular home hours.
The intent module 224 determines that the user 201 is starting to cook dinner and may likely need a recipe if the user 201 is taking out ingredients from the fridge after work. The intent module 224 determines that the user 201 is working and may need coffee if the user 201 is yawning in front of the computer. The intent module 224 determines that the user 201 is about to watch TV and will likely need program recommendation or snacks if the user 201 turns on the TV. The intent module 224 determines that the house will be vacant and the user 201 will need to turn off house appliances if the user 201 is the last person to leave the house. The intent module 224 determines that the user 201 is going out if the user 201 is putting on shoes in one room and grabbing keys in another room. The intent module 224 determines that the user 201 may likely need an umbrella if the sensor data indicates that it will rain. The intent module 224 determines that the user 201 will likely restock a particular food or house supplies if the sensor data indicates that the food or house supplies have a low stock. The intent module 224 determines that the user 201 may be interested in knowing promotions on items that the user 201 regularly orders if there are promotions.
In addition, the intent module 224 determines that the pet is hungry and needs to be fed if the pet regular feeding schedule has been missed. The intent module 224 determines that the user 201 is likely to water a plant if the user 201 waters the plant every week. The intent module 224 determines that the user 201 may need to do house cleaning if the sensor data indicates that clothes are scattered around the house/apartment. The intent module 224 determines that the user 201 may need to do the laundry if the sensor data indicates that the laundry basket is full. The intent module 224 determines that the user 201 may need to do the dishes if the sensor data indicates that the dishwasher is full or nearly full. The intent module 224 determines that the air conditioner needs to be adjusted if the person is sweating or is rubbing hands with hunched shoulders. The intent module 224 determines that a particular food may cause allergy to the user 201 if the sensor data indicates that the food includes an allergen.
The intent module 222 may provide the sensor data to one or more machine learning models to determine the intent. The machine learning models include one or more artificial intelligence models, classifiers (e.g., logistic classifiers, support vector machines, and multi-class classification), decision trees, neural networks, deep learning models, or any combination thereof. The machine learning models include correlations between the intent and sensor data. The sensor data includes activity features, schedule features, behavior features, environment features, and the like. In some embodiments, the machine learning models include correlations between one or more features included in the sensor data and the intent. For example, model parameters of a logistic classifier include the coefficients of the logistic function that correspond to different features included in the sensor data.
As another example, the machine learning models include a decision tree model, which is a directed acyclic graph where nodes correspond to conditional tests for a feature included in the sensor data and leaves correspond to classification outcomes (i.e., presence or absence of one or more features). The parameters of the example decision tree include (1) an adjacency matrix describing the connections between nodes and leaves of the decision tree; (2) node parameters indicating a compared feature, a comparison threshold, and a type of comparison (e.g., greater than, equal to, less than) for a node; and/or (3) leaf parameters indicating which intent corresponds to which leaves of the decision tree.
The intent module 224 creates machine learning models (e.g., determines the model parameters) by using training data. The training data includes a set of raw or analyzed sensor data labeled with features. For example, the training data are sensor data for which features have already been identified (e.g., by the health module 224, by the user 201, by an administrator, by an expert, or a combination thereof). The intent module 224 determines the model parameters that predict the intent associated with the sensor data. For example, the intent module 222 determines an objective function indicating the degree to which the determined intent matching the intent indicated in the training data. The health module 222 modifies the parameters to optimize the objective function, thereby reducing differences between predicted intent and actual intent.
One example of labeled training data is illustrated in
The intent module 224 further updates machine learning models (e.g., model parameters of the machine learning models) using information received, for example, via the user interface 202. For example, after the robot 102 determines an intent based on the sensor data, the robot 102 confirms with the user 201 on the intent. The user's 201 positive feedback (e.g., confirmation) indicates that the machine learning models are accurate and negative feedback (e.g., disapproval) indicates that the machine learning models need to be improved.
The response determination module 226 determines the robot's 102 response based on the user's health condition or based on the user's intent. For example, if the health module 222 determines that the user 201 may have a potential health problem, the response determination module 226 determines to confirm with the user 201 on whether the user 201 needs assistance and/or to offer assistance. If the user 201 affirms, the response determination module 226 determines to contact another party (e.g., a physician, an emergency contact, another user nearby, etc.) and/or to provide assistance. For example, the response determination module 226 determines to ask the user 201 for additional input thereby to diagnose the user 201, and/or fetch medicine, water, tissue, or other supplies. The response determination module 226 approaches another individual nearby to communicate and/or calls another individual via telephone or text. If the health module 222 determines that the user 201 is injured, the response determination module 226 determines to confirm with the user 201 whether an emergency call should be placed and/or to contact places an emergency call. If the health module 222 determines that the user 201 faces a health risk, the response determination module 226 alerts the user 201 about the health risk (e.g., carbon monoxide, mold, etc.) and asks for further instructions.
The response determination module 226 may further associate information such as the user 201's confirmation, instructions, and diagnosis with the sensor data and store the information in the user data store 230 and the health data store 232. The control system 220 may provide log daily observations of health state for later analysis by the robot or medical professionals.
The response determination module 226 may determine to complete the task to further the determined intent and/or to confirm with the user to receive further instructions. For example, if the intent module 224 determines that the user 201 intends to perform an action on an object (e.g., have a water bottle, pick up a box, carry a dish, etc.), the response determination module 226 determines to perform the action. If the intent module 224 determines that the user is performing a routine (e.g., waking up, goes to bed, goes to work, arrives at home, cooking dinner, watching tv, working, etc.), the response determination module 226 determines to offer assistance or to provide the assistance (e.g., making the coffee, locking all doors, turning on or off home devices, bringing the laptop, providing recipes, recommending tv programs, bringing snacks, etc.) If the intent module 224 determines that the schedule is due (e.g., feeding schedule, watering schedule, ordering schedule, laundry schedule, etc.), the response determination module 226 determines to offer assistance or to provide the assistance (e.g., feed the pet, water the plant, order pantry items or house supplies, etc.) If the intent module determines that the user will likely need a particular object (e.g., an umbrella, a promotion, a new release, etc.) or perform a task (e.g., do the laundry, do the dishes, adjust the air conditioner), the response determination module 226 determines to offer assistance or to provide the assistance (e.g., bring the umbrella, notifies the promotion, notifies the new release, put the clothes in the laundry basket or in the washing machine, load the washing machine, load the dishes, start or unload the dish washer, etc.)
The control system 220 controls the robot 102 to react based on the response determined by the response determination module 226. The motion controller 226 determines a set of motions for the motion system 250 to perform based on the response determined by the control system 220. For example, if the response determination module 226 determines to go to a specification location, the motion controller 228 generates instructions to drive the locomotion system 254 (e.g., wheels, legs, treads, etc.) toward the location of the user 201. If the response determination module 226 determines to perform an action, the motion controller generates instructions to drive the robotic arms 252 to perform the action. The control system 220 may also communicate with the device 106 or the client device 110 to turn on or off a device, to send an alert to the user 201 via the client device 110, or to send an alert to another party.
The user data store 230 stores data about the user 201. The user data includes the user's personal information (e.g., age, height, weight, gender, face, etc.), health information (e.g., medical history, health records, allergy, etc.), behavior information (e.g., walking speed, speech speed, poses, routines, habits, a distribution of location, etc.), contact information (e.g., contact number, email address, home address, etc.), preferences (e.g., food, movies, books, hobbies etc.), wardrobe (e.g., casual clothing, work clothing, business clothing, special occasion, etc.) and the like.
The health data store 231 stores health condition data such as information describing illness and associated symptoms, information describing human behavior and associated medical conditions, information describing injury and associated human behaviors, information describing mental illness and physical manifestations, and the like. The intent data store 232 stores intent data such as information describing human behavior and associated tasks, information describing human behavior and associated objectives, information describing an environment and associated common human reaction in the environment, information describing a context and associated common human reaction in the context, and the like. The model data store 233 stores the machine learning models used by the robot 102. The machine learning models 102 may be trained by the robot 102. The machine learning models 102 may be additionally trained by the assistant platform 120 and deployed to the robot 102.
The motion system 250 includes physical components that carry out actions. For example, the robotic arms 252 can perform operations toward an object or a human. Example operations include touch, grasp, hold, move, release, wave, shake, lift, drop, place, turn, twist, and the like. The robotic arms 252 can have various ranges of motion.
