Abstract: The purpose of this project is to develop a transplanter of pineapple seedlings in Taiwan which is in accordance with the intelligent machines & tools and also the human-machine assistant devices in order to solve the problem of labor shortage in agriculture. The data of field for pineapple growth are: ridge width=100cm, row spacing=50cm, crop spacing=30cm, row on each ridge=2. The planting method is triangular arrangement. The number of pineapples per hectare is 30,000–40,000. During the
transplanting the work of putting and planting of seedlings are done by hand separately. The drawing of transplanter design for pineapple seedlings will be finished by midterm examination. The height of ridge surface and length of pineapple seedling are about40–50cm. This length is longer than that of vegetable seedling. Therefore the height of whole mechanism for transplanter will be greater. A prototype of transplanter for pineapple seedlings will be completed by final examination. The preliminary transplanting tests in field will also be carried out with local farmers.
