Making Agriculture More Intelligent: Progress of Agricultural Robots

Abstract

In this paper, we present a mini review to investigate the development progress of agricultural robots from different perspectives including classification, functionality, and characteristics. The current technical situations and features of grafting robot, picking robot, weeding robot, spraying robot, etc. are introduced with their corresponding application contexts. It is analyzed and concluded that high cost and intellectualization are two major factors that may challenge the popularity of agricultural robots. The development trends of agricultural robots are discussed as well.
