This project presents the design and development of a Smart Rescue Robot for Human Detection using IR Remote Control. The robot is built using an Arduino Nano as the central controller, which coordinates all input and output operations. The movement of the robot is controlled wirelessly using a TV IR remote through a TSOP1738 IR receiver, allowing the user to operate it in four directions: forward, backward, left, and right. For human detection, a PIR (Passive Infrared) sensor is integrated into the system. The PIR sensor detects the presence of a human based on body heat (infrared radiation). When a human is detected, the system immediately activates a buzzer to alert rescuers, making it highly useful in search-and-rescue operations, especially in disaster-affected areas. The robot uses an L298 motor driver to control DC motors for movement, and it is powered by a rechargeable battery, ensuring portability and continuous operation. The combination of remote navigation and automatic human detection makes this system efficient, cost-effective, and suitable for real-time rescue missions. Overall, this project demonstrates a reliable and intelligent robotic solution for assisting in human detection and rescue operations with simple control and alert mechanisms.      

The main objectives of the project are:

  To design and develop a compact rescue robot using an Arduino Nano as the main control unit.

  To enable wireless control of the robot using an IR remote through the TSOP1738 IR Receiver for movement in forward, backward, left, and right directions.

  To implement human detection using a PIR Sensor based on body heat sensing.

  To provide an alert system using a buzzer when human presence is detected.

  To control the robot’s movement efficiently using an L298 Motor Driver and DC motors.

  To ensure portability and continuous operation using a rechargeable battery.

  To develop a low-cost and user-friendly rescue system for disaster management and surveillance applications.
