Pickup and Drop System for Seedling using Gantry Mechanism

Abstract

This paper describes the design and operation of a sapling pickup arm for an automated vegetable seedling transplanter. The sapling pickup arm minimizes seedling damage, lowers labour expenses, and improves efficiency to overcome the drawbacks of hand transplanting. The arm is made up of multiple essential parts. While an intelligent positioning mechanism assures precise insertion in planting cups, a gentle gripper securely grasps seedlings. A sophisticated control system adjusts to different planting conditions and synchronizes motions. Combining mechanical and electrical systems further improves the arm's functionality for accurate seedling delivery. Proper plant spacing is ensured by a measuring unit powered by a stepper motor and an electronic system. Rotating fingers on the measuring shaft are used to remove seedlings from pro-trays. There are more advantages to the transplanter's three-dimensional movement. Planting over a wide area is made possible by lateral movement (X-axis), while precise depth adjustment for various vegetable varieties is made more accessible by vertical movement (Y-axis). This adaptability is essential for the best possible plant growth. This innovative design is critical in automating vegetable transplanting, offering significant advantages over traditional methods. Future research directions could improve the arm's agility and adaptability to handle various seedling shapes and sizes.
