The design of this intelligent grapefruit picking robot is based on the migration,analogy and improvement of other related fruit and vegetable picking robots.According to the functional requirements of the intelligent grape-fruit picking robot,sheet metal parts are selected to make the robotic arm part,and soft 3D printed photosensitive resin is used as a flexible finger.The track mechanism suitable for walking in the hilly area and the STC series of mi-crocontroller are selected to control the track walking and hand picking actions.By combining OpenMV,camera and other external devices with obstacle avoidance sensors,grapefruit recognition,picking and obstacle avoidance walking can be achieved.The intelligent grapefruit picking machine greatly reduces the picking cost,indirectly im-proves the transportation efficiency,delivers more fresh grapefruit to the market in time,and also liberates people from the single boring labor of picking grapefruit.
