A review on multirobot systems in agriculture

Agricultural multirobot systems (MRSs) are expected to be essential in future agriculture. Therefore, MRSs comprising an aerial robot, a ground robot, and a manipulator are being actively studied for application in agriculture. However, MRSs are still being researched and several challenges need to be addressed. Moreover, no comprehensive surveys or detailed analyses of agricultural MRSs exist. Therefore, we systematically investigated and reviewed an MRS used in agriculture in terms of platforms, control, and application. This review primarily considers state-of-the-art research on agricultural MRSs and covers the developed platforms and controls applied to the field with subtasks. Furthermore, we introduce recent trends and analyze the problems and limitations of various MRSs. Finally, we discuss the points that need to be considered for commercializing agricultural MRSs and the expansion of their applications to the fields of geosciences and life sciences. Future research on the proposed agricultural MRS can help with advancements in the robotics market.
