Abstract:

A control system of a mini-weeding-robot platform was developed based on C8051F340 single-chip microcomputer and tested in paddy field. The design process of the hardware and the flow of the software were described. The control system was composed of three module, the onboard control system module, the data translation and transmission module on PC and the remote control module. The remote control module can complete automatic navigation control with the image information and manual remote control. Field test results show that the mini-weeding-robot platform can walk in the paddy field with the speed of 0.2 m/s, eight-degree-of-freedom movement, and rapid response speed of 30 ms. The clean rate was 81.3% and the injury rate of rice seedlings was 3.6% using mechanical touching weeder.

Key words: agricultural engineering, rice paddy field, mini-weeding-robot platform, control system, design and testing
