Agriculture robotics can better serve the agricultural production by studying agricultural robotics technology further, and then increase agricultural mechanization. The author read a lot of related data and had a further study on agricultural robotics. It is found that the application of agricultural robot is more and more wide. It greatly reduces the labor intensity and increases labor efficiency and makes up the shortage of labor scarcity. However, there are some shortcomings on the application of agricultural robots. The improvement and innovation of agricultural robots will bring greater economic benefits and become an important way of modern agricultural development. The author described the latest concept and characteristics of agricultural robot in recent years, analyzed the importance and necessity of agricultural robot, introduced the existing agricultural robot feature, application field. On the basis, some suggestions are proposed on the trend of application and development of robot technology in agriculture.
