Abstract

n

n

nThe growing demand for assistive technologies in healthcare and elderly care has driven the development of intelligent robotic systems. This research work describes the design, hardware integration, and software implementation of a caretaker bot built around the Raspberry Pi 4B module. The system combines essential components such as a speaker, a buzzer, a power bank for portability, a SIM card module for cellular connectivity, and a mobile application for real-time notifications. In addition to the hardware specifications and interconnections, the study details the Raspberry Pi 4B pin diagram, provides an overview of the operating system installation and configuration, includes sample Python code for audio recording and notification functionality, and outlines the system’s overall architecture using block diagrams and flow charts. The final output showcases a fully functional prototype designed to monitor events and deliver timely alerts. This system proves to be an effective solution for remote caregiving and emergency support, offering real-time updates that enhance responsiveness and safety. By integrating sensor-based monitoring and instant notifications, it ensures that critical situations are promptly addressed, thereby reducing response times. Its reliable performance and ease of deployment make it a valuable tool for elderly care, patient supervision, and other vulnerable scenarios. Overall, the prototype highlights the potential for scalable implementation in healthcare and smart home environments requiring remote oversight.nn
