Abstract
Nowadays, awareness of foods safety is increasing. People say that organic farming is great about safety of foods because it does not use weed killers and chemical fertilizer and so on. However, the spread of organic farming is difficult because fanners are burdened weeding the rice field with their hands. The research arm of this study is to develop a 5-DOF weed removal robot arm with an end effector consists of a cutting part and a grasping part. We adopt a system from a grass cutter saw for the cutting part, reciprocating saw cuts weed ear part, and adopt a system like a scissors of pole pruner for the grasping part, grasping and releasing weed ear part. After we developed the robot arm, we evaluate the performance throughout experiments.
