Abstract: With development of technology and increasing demand for agricultural efficiency and quality by humans, agricultural inspection robots, as an important tool in modern agricultural field, can replace traditional manual inspection methods to improve inspection efficiency and accuracy, reduce labor costs, and provide strong guarantees for agricultural production．Focusing on characteristics of greenhouse track planting mode scenarios, control system of plant inspection robot was explored, including architecture, hardware composition, software design, and navigation system of control system．Through in-depth research on these aspects, better understanding of working principle and performance of plant inspection robot could be achieved, to provide theoretical support for further optimizing of robot's performance and improvement of plant inspection efficiency and quality．
