In the progress of precision farming, it is very important to collect variety of information on crops and field. In this study, we developed a prototype mobile eggplant grading robot in order to get information that be used for presentation of better way on cultivation. This robot can collect and accumulate the fruit's features information and location information at the same time while harvesting. After the field test experiment, a prototype mobile eggplant grading robot has achieved its purpose which was acquiring and storing information in real time and has created field spatial maps from the information. In the previous experiments, a rotary encoder was used in order to discriminate plant location based on the distance from the start point of the robot. However, the detecting error of the distance increased in proportion to the travelling distance of the robot because of the slip of the rotary encoder. In this paper, the robot discriminated plants by using IC tags attached to individual plants and a transmitter-receiver mounted on the robot. From the results, the robot could discriminate individual plants correctly.
