Design of A Wireless Lawn Mower Robot Based On ESP32-cam Using Intranet Network

Abstract

The advancement of robotics technology significantly contributes to facilitating human tasks, including the often overlooked task of grass cutting. This research introduces a robot design to assist many, particularly in situations like grass cutting at airports. The implementation system employs the ESP32-CAM wireless controller module within an intranet network, enabling control of the grass cutter through a web browser. It utilizes the OV2640 camera module for visualizing the grass area, ESP32 Wi-Fi module for communication, and the L9110 fan motor for the grass cutter blade. Robot control can be accessed via the IP address provided by the ESP32 module, accessible through a web browser on a laptop or smartphone. This prototype can handle grass with a height of 3-5 cm, provided that the robot and controller are on the same network. Despite testing with a limited operational range using a mobile hotspot, the wireless lawn mower robot can operate for 10 minutes on a full battery charge. However, it's crucial to note that this robot is only suitable for smooth and flat terrain, and cannot overcome obstacles larger or taller than itself. This research aims to promote broader adoption of robotics technology, streamlining various human activities.
