[0002] With the continuous improvement of people's living standards, the planting area of ​​yam, an agricultural product with high nutritional value and health benefits, is constantly expanding. However, because yam is a rhizome plant that grows very deep in the ground, sometimes reaching tens of centimeters in length, harvesting it is extremely difficult. Furthermore, as a rare and specialty agricultural product, the marketability of yam greatly influences its selling price, primarily manifested in the amount of root hairs and the integrity of the tuber. These characteristics are easily damaged during traditional yam harvesting, directly impacting farmers' income. Therefore, yam harvesting has become a bottleneck limiting yam growers' profits. The traditional method of yam harvesting is manual harvesting, which is not only inefficient but also prone to damaging the yams.
