The robot is designed to support healthcare staff by detecting critical situations and interacting with patients:

• Fall detection: identifies when a patient has fallen using onboard cameras and accelerometers.

• Consciousness check: asks simple voice questions (e.g., “What day is it?”) to evaluate awareness.

• Patient recognition: identifies patients via QR code or facial recognition.

• Emergency response: autonomously moves to the patient’s room when a fall or abnormal event is detected.

• Patient call function: allows patients to request the robot by pressing a call button.

The Ehpad Patrol can move independently and safely throughout the facility:

• Mapping and localization: builds a digital map of corridors and rooms for navigation.

• Obstacle detection and avoidance: avoids both static and moving obstacles in real time.

• Automated path following: follows predefined or dynamically updated routes.

The robot continuously collects, analyzes, and transmits health and environmental data:

• Vital parameter measurement: monitors temperature, heart rate, and blood oxygen level.

• Data logging and storage: securely stores patient data and activity logs on a remote server.

• Supervision web interface: displays patient information, alerts, and robot status in real time.

• Wireless communication: uses Wi-Fi to send alerts and updates to healthcare personnel.
