  "claims": [
    "1. An excrement care robot with an integrated analysis function on the motion and condition of a bedridden patient, the excrement care robot comprising: a body-fitted type treating apparatus including a body which has a shape corresponding to bends of the genitals and buttocks of a human body and is formed with a treatment space that is opened in a direction of the genitals and buttocks of the human body to receive excrement discharged from the human body, a discharge unit which is provided in the body and communicates with the treatment space to discharge the excrement of the treatment space to the outside, and a sensor unit that is provided in the body to measure a direction of movement of the body; and a motion analysis unit that receives sensor data of the sensor unit to analyze the motion of the human body through the movement of the body.",
    "2. The excrement care robot of claim 1, wherein the sensor unit comprises an inertial sensor that measures rotation angles with respect to a X (pitch) axis, a Y (roll) axis, and a Z (yaw) axis of the body.",
    "3. The excrement care robot of claim 2, wherein the motion analysis unit determines that a user takes a position of lying on his/her side when an amount of change in rotation angle of the X-axis is less than a first angle range in a + direction or − direction within a predetermined first time range.",
    "4. The excrement care robot of claim 2, wherein the motion analysis unit determines that the user is in a poor wearing condition when the amount of change in rotation angle of the X-axis is equal to or greater than the first angle range in the + direction or − direction within the predetermined first time range.",
    "5. The excrement care robot of claim 2, wherein the motion analysis unit determines that the user takes a sitting position or is in a poor wearing condition when the amount of change in rotation angle of the Y-axis is equal to or greater than a second angle range in the − direction within a predetermined second time range.",
    "6. The excrement care robot of claim 2, wherein the motion analysis unit determines that the user is in a removal condition or in a poor wearing condition when the amount of change in rotation angle of the Y-axis is equal to or greater than the second angle range in the + direction within the predetermined second time range.",
    "7. The excrement care robot of claim 2, wherein the motion analysis unit determines that the user is in a removal condition or in a poor wearing condition when the amount of change in rotation angle of the Z-axis is equal to or greater than a third angle range in a + direction or − direction within a predetermined third time range.",
    "8. The excrement care robot of claim 2, wherein the motion analysis unit determines that the user is in any one of a fall condition, an emergency condition, or a removal condition when the amount of change in rotation angle of the X-axis is equal to or greater than the first angle range in the + direction or − direction, the amount of change in rotation angle of the Y-axis is equal to or greater than the second angle range in the + direction or − direction, and the amount of change in rotation angle of the Z-axis is equal to or greater than the third angle range in the + direction or − direction.",
    "9. The excrement care robot of claim 1, wherein the motion analysis unit generates history information on position change of the user over time through the sensor data measured by the sensor unit.",
    "10. The excrement care robot of claim 1, further comprising: a communication unit that transmits the sensor data measured by the sensor unit to the motion analysis unit."

  "description_excerpt": "(a) Technical Field The present invention relates to an excrement care robot which is formed to be wearable on a human body to treat excrement, and more particularly, to an excrement care robot which is formed to perform an integrated analysis of the motion and condition of a bedridden patient to quantify a position change of the bedridden patient and induce an appropriate pressure distribution based on a position change history. (b) Background Art In general, people such as patients, the elderly, etc., who have difficulty in moving or who have difficulty moving their lower bodies at will, have no ability capable of treating excrement on their own, so that there is a discomfort that a guardian or caregiver must always reside around the people. Therefore, in order to solve such discomfort, the research and development of an excrement treating apparatus that comes into direct contact with a human body to collect the excrement have been conducted. Such an excrement treating apparatus is designed to receive the user's excrement, suck the received excrement, and then discharge the sucked excrement to the outside, so that the excrement can be automatically treated even if a guardian or caregiver does not reside around the user.\n\nHowever, conventional excrement treating apparatuses which have been developed up to date often focus on only an excrement treatment function, and are designed without considering the user's body, and thus, there is a problem that the usability is very poor.",
