Abstract: It first designed the experimental platform of agricultural mowing robot from five modules, such as motion control, energy, sensor, core processor and mowing. Then, it analyzed and studied the obstacle image segmentation algorithm by using texture features. Finally, it realized the full area coverage operation of the mower is based on CCD^*. The experimental results showed that the use of the CCD^* algorithm greatly improves the ability of the mowing robot to cover all areas, and improves the work efficiency of the mowing robot.
