Research Progress of Autonomous Robot Navigation Technology for Indoor Farm

Robot navigation technologies such as vision navigation, laser navigation, satellite navigation and road sign navigation were introduced, and navigation accuracy, real-time and adaptability of different types of robot navigation technologies in specific application scenarios were analyzed．According to characteristics of these navigation technologies, combined with results of navigation technology test conducted in the indoor farm of Meizhou Golden Green Modern Agriculture Development Co., Ltd., problems existing in application of single navigation technology in indoor breeding farms were pointed out, and application prospect of navigation technology based on information fusion of multiple navigation methods in indoor breeding farms were looked forward, hoping to provide ideas for breaking through key technologies of robot feeding, transportation and picking, and solving problems restricting development of intelligent and unmanned agriculture．
