In traditional aquaculture, the intervention of external factors on
aquaculture objects is less, which mainly depends on artificial feed feeding, parameter
monitoring and water quality regulation, which is time-consuming and labor-
consuming and inefficient. With the rapid development of new generation information
and intelligent equipment technology, these modern technologies have been gradually
applied to traditional aquaculture, and the key links of aquaculture have been deeply
studied and applied, which has effectively improved the efficiency of aquaculture
and promoted the rapid development of aquaculture. In order to understand the
architecture, development and application of aquatic robots more comprehensively,
and to understand the research status of key technologies of aquatic robots, this paper
first discusses the classification and typical system architecture of main aquaculture
robots in detail, and then focuses on the key technologies of aquaculture robots, and
then summarizes and analyzes the research progress from five aspects: navigation
system, sensing system, data transmission, decision model and feedback execution.Based on the analysis of the bottlenecks of each key technology, this paper points
out the main problems restricting the application and popularization of aquaculture
machines, and gives some relevant suggestions. Finally, the research on the key
technologies of aquaculture robots is summarized and prospected. It is hoped that this
paper can provide a reference for the key technology breakthrough and large-scale
popularization and application of aquaculture robots.
