Development of a PID Controller-Based Portable Seeder Design for Corn Seeds

Corn is a major crop in Thailand and plays a crucial role in feeding people locally and being sold to other countries. Because of its importance, farmers focus a lot on growing corn. Nowadays, many farmers are growing corn to earn more money from their land. As more land is used for corn, there’s a growing need for new ways to plant the seeds. This is where a special machine comes in, a seeder that carefully places corn seeds in the ground according to how they should be planted in fields where corn is grown. In one seeding pass, the machine will press the center and form two rows of mounds with a distance of 25-50 cm between them. In these two mounds, corn seeds will be placed at intervals of 6-8 cm for each row. The design of this seeder machine is made portable so that it can adapt to all types of tractors used as propulsion.
