Abstract :

The Advancement Of Internet Of Things (IoT) And Embedded Technologies Has Significantly Contributed To The Development Of Intelligent Assistive Systems For Healthcare And Mobility. This Paper Presents The Design And Implementation Of An IoT-Enabled Moving Wheelchair Robot With Obstacle Detection And Continuous Health Monitoring, Aimed At Enhancing The Safety, Independence, And Well-being Of Individuals With Mobility Impairments. The Proposed System Is Built Around The NodeMCU ESP8266 Microcontroller, Which Facilitates Real-time Data Acquisition, Processing, And Wireless Communication With A Cloud-based IoT Platform. The Wheelchair Is Equipped With An Ultrasonic Sensor For Obstacle Detection, Enabling Real-time Collision Avoidance By Automatically Stopping The System And Generating Alerts When Obstacles Are Detected Within A Predefined Range. In Addition To Navigation Safety, The System Integrates Biomedical Sensors, Including The MAX30100 For Heart Rate And Blood Oxygen Saturation (SpO₂) Monitoring, And The LM35 Sensor For Body Temperature Measurement. These Sensors Continuously Track The User’s Vital Parameters And Transmit The Data To A Web-based Dashboard For Remote Monitoring By Caregivers Or Medical Professionals. To Further Enhance Situational Awareness, An ESP32-CAM Module Is Incorporated For Live Video Streaming, Allowing Real-time Visual Monitoring Of The User’s Surroundings. The System Also Includes A Buzzer Alert Mechanism To Notify Users And Caregivers In Case Of Abnormal Health Conditions Or Obstacle Detection. Experimental Results Demonstrate Reliable Performance In Obstacle Detection, Accurate Health Monitoring, And Efficient IoT-based Data Transmission With Minimal Latency. The Proposed System Offers A Cost-effective, Integrated Solution That Combines Mobility Assistance, Healthcare Monitoring, And Remote Supervision. It Is Particularly Beneficial For Elderly Individuals, Disabled Persons, And Patients In Homecare Or Rehabilitation Settings. The Work Highlights The Potential Of Combining IoT, Robotics, And Biomedical Sensing To Develop Smart Healthcare Devices, With Future Scope For Incorporating Artificial Intelligence And Advanced Navigation Systems
