Due to the lack of water resources and Iran’s location in a hot and dry geographical area, the tendency to produce agricultural products with the least water requirements is one of the most important measures to produce capital in the agricultural sector. Saffron is a medicinal and aromatic plant that has long been specific to the Iranian ecosystem, and more than 90% of the global production of this product is in Iran. Factors such as the task being time-consuming due to having to harvest by hand, flowers being damaged and destroyed, high labor costs and labor fatigue, and monotony of harvesting are among the issues of the traditional harvesting method that limit the expansion of cultivation and eventually exports abroad. Due to the lack of labor force in harvesting time and a late harvest, nearly one-third of the product is wasted. Besides, workers’ wages in flower picking and stigma removal take up more than one-fifth of the cost of each kilogram of saffron produced.

Ramis’s team designed a semi-mechanized device to help harvest saffron according to the requirements of the market and the level of farmers’ income. This device is a moving chassis that is powered by electricity and is environmentally friendly and rechargeable. By sitting or lying on this machine, the farmer will be able to control the navigation of the machine along the field and will be able to harvest the crop with minimal damage dealt.
