Its main function is to accurately remove weeds in farmland through laser irradiation, thereby achieving a weeding effect without chemical pollution. The laser weeding robot can efficiently remove weeds and improve agricultural production efficiency. The robot can accurately identify weeds and crops to ensure that crops are not damaged during the weeding process. In addition, laser weeding technology completely abandons the use of chemical herbicides, achieves a weeding effect without chemical pollution, and is conducive to the sustainable development of agriculture.
