Abstract: Patrol detection is an important form of deep space exploration. The planetary rover, which can move on the surface of solid-state planet and complete the tasks of exploration, sampling and transit, has many functions, such as expanding the scope of fine detection on planet surface, overcoming the impact of landing accuracy, reducing the workload of astronauts and so on. The technical development of lunar rover, Mars rover and others are reviewed focusing on the development of locomotion technology, navigation control technology, autonomous and intelligent technology, thermal control technology, ground test verification technology, remote operation technology, and the development trend of rover technology is analyzed.
