Precise feeding of bait, medicine and microorganism is an important part of healthy aquatic breeding. The research of intelligent bait-dropping boat has gradually attracted attention due to its automatic cruise, obstacle self-avoidance, multi-point accurate delivery, supporting for the integration of water quality and video monitoring. The domestic and foreign research of intelligent bait-dropping boat was summarized from three aspects, including bait-feeding structure, path control and bait-feeding strategy. Among them, the existing conveying and throwing structure, path control mode, heading control algorithm, feeding path strategy and intelligent feeding technology were systematically analyzed. In view of the current research deficiencies, the future R&D trends were obtained: further improvement of bait breaking rate and throwing uniformity, high-precision navigation and positioning system integrated with 5G communication, high-precision heading control algorithm, intelligent bait-dropping algorithm that combined visual and acoustic information analysis, more multifunction of intelligent feeding boat, construction of a remote monitoring system for smart bait-dropping boat based on satellite Internet of things and digital twins. The content was of great significance to the development of digital, precise and intelligent of the intelligent bait-dropping boat.
