His grandmother needed to work very hard under the hot sun and sometimes would badly hurt her fingers when using her harvesting tools. 16 To make things easier for his grandmother, Yang thought of creating a machine that could automatically（自动地） harvest lotus roots. With the help of his teacher, Yang spent nearly a year building the model of the robot. The robot moves on its own through the muddy（泥泞的） field. It uses image recognition（图像识别） to find roots by looking at the color of the lotus leaves. The machine's arm then cuts the mature （成熟的） lotus roots. When Yang showed the machine to his grandmother, she was happy and gave some useful suggestions for improvement. She suggested using the audio player to show the robot's location in dense（稠密的） lotus leaves. “My grandmother's suggestion reminded me that any invention must have true value,” said Yang. Although Yang thought he still needed to make improvements, like finding cheaper ways to make the machines, his spirit was praised by many people. His teacher once spoke highly of Yang, “He is a boy which always thinks creatively.. . Whenever he comes across problems in life, he always works hard to solve them.” 1.
