China's grape planting range is wide, the yield is large. In the production link, the time of picking and harvesting is short, labor-intensive and the amount of labor is large. The traditional way of hand-picking cannot meet the requirements of grape industrialization and large-scale production. A new type of automatic grape harvesting robot is designed. The robot is composed of harvesting main engine and transport auxiliary unit. By visual recognition technology and near infrared spectrum detection technology to achieve accurate positioning of grapes, and judge its maturity and quality; The bionic octopus flexible mechanical arm is used to pick grapes. The flexible structure with high degree of freedom can adapt to the complex environment in the vine, wrap and hold the grape cluster in a curling way, and prevent the grape from falling. There are fruit branch scissors at the front end of the bionic octopus tentacle robot arm to realize the separation of grape bunches and grapevines; The process of grape packaging and labeling is completed in the collection host; The auxiliary transport machine is connected with the main machine, and the rotating structure is designed to exchange the empty basket with the grape basket on the main machine, so as to ensure the continuous picking of the main machine; The transport auxiliary machine will transport the packaged grapes back to the warehouse, and then it can be directly transported to the market for sale. The device has self-adaptability in structure, can adapt to different planting methods and different kinds of grapes all over the country, in line with the concept of green sustainable development, with high market value and economic benefits.
