Harvesting Washington state's vast fruit orchards each year requires thousands of farmworkers, and many of them work illegally in the United States.
That system eventually could change dramatically as at least two companies are rushing to get robotic fruit-picking machines to market.
The robotic pickers don't get tired and can work 24 hours a day.
"Human pickers are getting scarce," said Gad Kober, a co-founder of Israel-based FFRobotics. "Young people do not want to work in farms, and elderly pickers are slowly retiring."
FFRobotics and Abundant Robotics, of Hayward, California, are racing to get their mechanical pickers to market within the next couple of years.
Harvest has been mechanized for large portions of the agriculture industry such as wheat, corn, green beans and tomatoes for some time. But for more fragile commodities like apples, berries, table grapes and lettuce - where the crop's appearance is especially important - harvest is still done by hand.
Members of Washington's $7.5 billion (roughly Rs. 48,217 crores) annual agriculture industry have long grappled with labor shortages, and depend on workers coming up from Mexico each year to harvest many crops.
But President Donald Trump's hard line against immigrants in the US illegally has many farmers in the country looking for alternative harvest methods. Some have purchased new equipment to try to reduce the number of workers they'll need, while others have lobbied politicians to get them to deal with immigration in a way that minimises harm to their livelihoods.
"Who knows what this administration will do or not do?" said Jim McFerson, head of the Washington State Tree Fruit Research Center in Wenatchee. For farmers, "it's a question of survival."
Washington leads the nation in production of apples and several other crops. Harvest...
