Spring is here, and it is time to enjoy West Lake Longjing tea. Usually, we think of workers picking tea leaves by hand. But now, some Longjing tea is being picked by smart tea-picking robots!
In a Hangzhou tea garden, a smart tea-picking robot developed by Zhejiang SciTech University begin to work for the first time. "We took thousands of pictures of new tea buds (芽) and put them into the robot for it to learn. The robot uses an AI model to recognize (识别) the buds it needs to pick,"said Professor Chen Jianneng, Party branch secretary (党支部书记) of the research team. This lets the robot find the right tea buds about 90% of the time.
The robot's arm pulls and sucks (吸) up the tea buds. These buds are quickly moved into a special box. After the robot collects all the buds from the area it's working at, it moves the buds from the box to a main box.
The robot was made because there are not enough people to pick tea leaves. In Zhejiang, about 400,000 more pickers are needed now. "Picking is the biggest challenge for the development of the tea industry," said Professor Wu Chuanyu, who leads the research team.
"Tea-picking robots are a trend (趋势) of the future," said Wu. About five years from now, the robots will do the job of picking West Lake Longjing tea instead of people, Wu added.
