Mechatronics Integrated Weeder with Traction and Stability Enhancements for Intra-Row and Inter-Row Agricultural Applications

Weed control in wetland paddy fields remains a challenge for Filipino rice farmers due to the limitations of manual and conventional mechanical weeders, especially in intra-row areas. This study introduces a Mechatronics Integrated Weeder designed for both intra-row and inter-row weeding, tailored for muddy field conditions in Barangay Pili, Sariaya, Quezon. The prototype features a galvanized cage wheel for traction, a float for stability, and an Arduino-controlled actuator for precise intra-row weeding. Finite Element Analysis (FEA) verified the structural integrity of key components, with maximum von Mises stress values (e.g., 1.11 MPa front, 28 MPa rear) far below material yield strengths. Field tests showed an average weeding efficiency of 77%, crop damage of 13.39%, and a field capacity of 0.032 ha/h at 1.9 km/h. Survey evaluations yielded high satisfaction scores: 4.33 for efficiency, 4.00 for functionality, and 5.00 for durability. Although the initial cost (∼P78,000) is higher than traditional tools, the long-term benefits include labor savings, improved productivity, and reduced fatigue. The prototype aligns with SDG 8 – Decent Work and Economic Growth, offering a sustainable, farmer-centered solution to modernize rice farming practices in rural communities.
