Initial Development of Remote-Controlled Coconut Harvesting Robot Prototype

Abstract

Coconut farming plays a big role in the Philippines' economy yet has faced persistent challenges due to the dangers of the manual harvesting process. This study presents the initial development of a Coconut Harvesting Robot Prototype, seeking to improve the country's coconut industry. The prototype comprises a climbing module, main body frame, and harvesting module, all designed to improve efficiency, safety, and address labor shortages. Through material selection, fabrication, and innovative control strategies, the robot offers a viable alternative to human tree climbing. A Programmable Logic Controller (PLC) serves as the central processing unit, enabling precise motor control and safety mechanisms. The evaluation phase involved assessing the robot's ascending and descending capabilities on a real coconut tree. The average climbing rate of 27.5 seconds and descending rate of 17.67 seconds demonstrate the robot's potential to enhance productivity. While this research is still in its initial stages, it lays the foundation for further development. Recommendations include refining attachment mechanisms, enhancing the robot's durability, and conducting comprehensive field trials. Although challenges persist, the potential this technology holds the promise of a safer and more efficient coconut harvesting, which is vital to the county's agricultural sector.
