Research Progress on Precision Pollination Robots for Facility Tomatoes
With the continuous promotion of the concept of agricultural modernization,the area of facility agriculture in China is constantly expanding,and it has ranked among the top in the world.Tomato is one of the important cash crops in facility agriculture,and timely,efficient and meticulous pollination of tomato flowers is the key to promote the growth of high-quality tomatoes.At present,the pollination of tomatoes in the facility is mainly carried out by hand,which accounts for a large proportion of labor and has high input costs.With the rapid development of machine learning,machine vision,the Internet and other technologies,pollination robots will become a key technology to replace human labor and improve production efficiency.In order to have a comprehensive and in-depth understanding of the development status and future trend of tomato precision pollination robots in facilities,this paper summarizes the development and application of pollination robots,analyzes the key technologies such as target recognition and detection of tomato flowers in facilities,summarizes the types and structures of tomato powder end effectors,summarizes the problems in the current research on picking end effectors and proposes solutions,and analyzes and discusses the development and practicability of liquid spray powder end effectors.Finally,the common problems encountered in the development of tomato pollination robot end effectors in current facilities are analyzed and prospected.
