This is important for hybrid breeding (杂交育种). Hybrid breeding helps plants grow stronger and produce more food. Yuan Longping created hybrid rice that has fed many Chinese people. According to Cell Press, the process usually means taking away the stamens (雄蕊) of the female plant (雌株) and then putting pollen (花粉) from the male plant onto the female plant. This helps the new plants get the best qualities from both parents. For example, if you mix a male plant that doesn’t get sick easily with a female plant that makes a lot of fruit, you can get a new plant that has both of these great qualities. However, hybrid breeding needs workers to do cross-pollination (异花授粉) again and again in a short time. This work takes a lot of time and energy. GEAIR solves the problem. It uses AI visual recognition and positioning (视觉识别和定位) technology to move among crops. After finding flowers, it uses robotic arms to do cross-pollination and finish the whole process. Building the robot was difficult because leaves get in the way, and flowers are very small. Traditional computers cannot easily find them in real time. To fix this, the research team trained a new model with 12,800 pictures of flowers. With this model, GEAIR can pollinate each flower in 15 seconds at a cost much lower than a worker’s yearly pay. 1．What is the name of the robot that can finish the whole plant breeding process 2．What is one advantage of hybrid breeding 3．What technology does GEAIR use to move among crops 4．Why was building GEAIR difficult (Give one reason.) 5．How long does it take for GEAIR to pollinate each flower Teachers find it difficult to collect students’ homework before class. To solve this problem, a 13-year-old middle school student invented a smart robot, and he got first prize in the Children’s Invention Awards. His parents are so proud of him. This smart robot can collect homework in a short time without making any mistakes. It uses Radio Frequency Identification (RFID;射频识别) technology—a reader and a special tag (标签) that can share information without touching each other. This way, it can help find and know what it is looking for. Each student’s notebook has a special RFID tag with their name and the subject. Students only need to place their notebooks on the robot, and the machine “sees” the notebook, “reads” its tag and takes it out of the name list. Teachers can check who hasn’t handed in homework by connecting their phones with the robot through Wi-Fi. Many teachers speak highly of the smart robot after using it. They think the boy will create mor ... ...
