Design and Implementation of Precise Operation of the Unmanned Rotary Cultivator

In order to realize the precise operation of unmanned rotary cultivator, the RTK carrier phase difference technique is used to measure the positioning accuracy of centimeter level, and according to the positioning data of RTK and the path tracking algorithm, the real-time path tracking control is carried out to make the unmanned rotary cultivator perform high-precision operation according to the expected route. The mavlink protocol is used to intercommunicate the control station on the computer side and the ArduPilotMega controller on the unmanned rotary cultivator side. According to the experimental results, the control system can effectively control the unmanned rotary cultivator running according to various scheduled operation routes, and the precision operation of unmanned rotary cultivator is realized.
