Abstract - The development of a Human Follower Robot incorporating IR and Ultrasonic Sensors represents an innovative venture in robotics and automation, aimed at creating a versatile machine capable of tracking and following targets while navigating obstacles. This project is fuelled by the vision of combining sensor technology, microcontroller programming, and robotic design to birth a robot capable of graceful traversal and intelligent target pursuit.

At its core, the project relies on the integration of two essential sensor technologies: Infrared (IR) and Ultrasonic sensors. IR sensors, functioning akin to human eyesight, detect objects by emitting and receiving infrared light, enabling the robot to recognize the presence of a target within its line of sight. Concurrently, ultrasonic sensors enhance the robot's perception by determining distances through sound waves, facilitating obstacle avoidance and maintaining a safe tracking distance from the target.

The project's foundation comprises key components working in tandem to fulfil the robot's objectives. A microcontroller, such as Arduino or Raspberry Pi, orchestrates actions by processing sensor data and regulating movements. IR sensors act as vigilant eyes, detecting the target, while ultrasonic sensors serve as the echolocation system, enabling seamless navigation in cluttered environments. Motors and wheels propel the robot, providing motion and directional control, while a reliable power supply, such as batteries, sustains its operations.

Four pivotal milestones define the project's core goals. Firstly, the development of algorithms and code for effective object detection using IR sensors enables the robot to discern the presence of a target. Secondly, obstacle avoidance mechanisms are implemented through ultrasonic sensors, ensuring adept manoeuvring around barriers and hazards. Thirdly, proximity control is prioritized to maintain an optimal and safe following distance from the target, preventing collisions. Lastly, efforts focus on enabling smooth and precise movement to ensure accurate and responsive tracking behaviour.

The potential applications of such a robot are diverse. Apart from assisting visually impaired individuals by guiding and avoiding obstacles, these robots can serve as automated tour guides, offering informative experiences in museums or exhibitions. Additionally, their utility extends to surveillance and security, where they can monitor areas and track intruders. Ultimately, this project holds promise for a future where intelligent robots seamlessly follow, guide, and protect, enriching lives with their remarkable capabilities.
