Design and Implementation of a Robotized Laser Module for Weed Control

This paper presents the design of a low-cost, modular system mounted on a mobile platform for weed control using laser technology. This proposal seeks to find an effective and sustainable solution for selective weed management in agricultural settings, avoiding harmful methods such as herbicides. The methodology for this work was based on the application of divergent-convergent thinking stages. Additionally, studies were conducted on potential movement systems, and in line with the system’s needs, a Core XY movement was selected. Standard elements and custom designs were adapted to the previous structure. Similarly, an analysis of potential casing designs was carried out, and through a convergent process, a design suitable for its function was selected. The results obtained in this work, such as the estimated movement system accuracy of less than 0.2mm and the simulated treatment time of 3.62 seconds, in an estimated area of 0,25 m2, demonstrate the feasibility of creating an effective, small-sized, and low-cost weed control system for users, providing the necessary precision to avoid damage to surrounding crops.
