Research progress of automatic navigation technology for orchard mobile robot.

Abstract

The existing related literatures were analyzed based on the current research progress of the orchard mobile robot's automatic navigation technology.According to the different environmental perception methods,the current research status of the navigation methods with perception systems based on laser,vision,machinery,electromagnetism,ultrasonic and GPS were discussed respectively;the advantages and disadvantages of each method in terms of navigation accuracy,real time,anti-jamming capability and the flexibility of the system were also discussed.Then we believe that the multi-sensor fusion technology could provide higher precision and stability for the orchard mobile robots' automatic navigation.On that basis,this paper proposed the development tendency of automatic navigation technology for orchard mobile robot in the future,multi-sensor fusion technology would become the main method of the environment perception for orchard mobile robot.Therefore,the development of the navigation system with required accuracy and stability for the orchard mobile robot would be the emphasis of the future research.
