Design of Intelligent Control System for Wheeled Drug Spraying Robot

Facing the problems of low manual efficiency and great harm to human body in the process of pesticide spraying, this paper puts forward a remote control solution ofof wheeled drug spraying robot, and designs the corresponding intelligent control system. The system takes Siemens S7-1200 PLC as the core controller, takes the touch screen as the man-machine interface, and combines the multi-sensor system to complete the allocation and control of the motor drive unit, so as to realize the functions of advancing, retreating, steering, speed regulating of the wheeled drug spraying robot. In addition, according to the experimental test results, PLC can realize the coordinated control of the drug spraying robot, and the whole system runs smoothly, responds quickly, and its operability and flexibility meet the design requirements, which provides a useful technical reference for realizing the automatic and intelligent operation of pesticide spraying.
