Mango is one of the characteristic fruits in the tropical region. The harvesting of mangoes is primarily done manually, which has presented issues such as high labor intensity and elevated costs. There has been an urgent need to develop mechanized harvesting technologies for mangoes. In this study, a mango picking robot is designed based on mango agronomic growth information, which can automatically identify the fruit and complete the picking and collection. By using YOLOv5 for mango fruit target recognition and combining the depth information provided by the depth camera D435i, the three-dimensional information of the picking point is obtained; A shear-clamp integrated end-effector is designed to effectively reduce the mechanical damage to the mango; A mango picking robot control system is developed basing on the ROS system; Testing experiments were conducted in laboratory environment, and the result of the experiments showed that the average time for the mango picking robot to recognize the fruit was 30.41 ms, the average picking time was 19.8 s, and the picking rate was 90.8%, which verified the control accuracy and stability of the picking robot. This study provides technical support for mango picking operation and helps to promote the intelligent development of agriculture.
