Robotics and System Technologies for Raising and Grafting Seedlings

In this paper the grafting seedlings production system was fabricated and investigated on the base of the plant factory concept. The y character grafting experiment was carried out by hand. As the result, the successful rate was 95 % with y character and 93.8 % with Y character. And it took 20 seconds for making one y character grafted seedling and 30 seconds for one Y character grafted seeding. The prototype robot could produce 2 seconds for one V character grafted seeding. And the successful rate was 46.9 % without black skin stems and run off between the scion and the stock that were damaged in this tube grasping. It was found that tube shape to grip the stems was not optimum. Now a y character type robot and a new tube are improving. Those experiments could show the possibilities that fabricated robot could work as 8 persons when the improved soft handling and alignment were carried out.
