Introduction
The rapid growth of industrial automation demands intelligent robotic systems that ensure high efficiency, low costs, and safety. Line follower robots, which autonomously follow predetermined paths using sensors, are widely used in industries for tasks like material transport and assembly. However, traditional line follower robots lack adaptability, especially in dynamic industrial environments where variable speed control is crucial—fragile items require slower speeds, while lighter goods can be moved faster.
To address this, the text presents an IoT-enabled line follower robot using an ESP32 microcontroller that supports Wi-Fi and Bluetooth for seamless remote speed control via the Blynk app. This system allows real-time speed adjustments, monitoring, and alerts through a GSM module to notify operators if operational limits are exceeded. This remote control improves workflow efficiency, safety, and flexibility, especially in hazardous or large-scale industrial settings.
The integration of IoT technologies like ESP32 and Blynk facilitates easy user interaction, real-time feedback, and maintenance scheduling, overcoming the limitations of traditional systems. The system exemplifies the future of industrial automation by enabling dynamic, remote, and safe control of robotic operations.
Additionally, related works cover various IoT and sensor-based robotic applications—from vehicle speed control and accident detection systems to medical delivery robots and weather monitoring—highlighting the broad potential of IoT in enhancing automation, safety, and operational efficiency across industries.
