The Pacific Northwest is an apple-growing powerhouse. About 80% of the United States\u2019 fresh apple crop is grown in Oregon and Washington<\/a>. <\/p>\n

\"Washington<\/p>\n

Washington State University’s apple picking robot has an inflatable arm designed to be gentler on the trees. The unit is lightweight and designed to function in modern trellised orchards.<\/p>\n

But farms have been experiencing worker shortages for various reasons, including the impacts of immigration crackdowns<\/a>, an aging domestic workforce<\/a> and challenges getting temporary international workers approved through the federal guest worker visa (H-2A) program<\/a>.<\/p>\n

Now engineers at Washington State University<\/a> are working on ways to make sure fruit doesn\u2019t rot on the trees by developing robots that can pick apples as gently and efficiently as humans do<\/a>. <\/p>\n

The new innovation from WSU is a soft robotic arm that inflates to extend a claw towards the target fruit. It then deflates to retract. The inflatable arm is made of a heavy-duty but pliable fabric that can bend and flex if the arm accidentally contacts a branch while extending toward the target fruit. <\/p>\n

The advantage of the soft inflatable arm is that it\u2019s less likely to damage the trees as it maneuvers in. It\u2019s also less likely to injure someone if they get too close.<\/p>\n

The arm can support a little over 2 pounds \u2014 enough to accommodate the apple-grabbing claw and a single ripe apple. <\/p>\n

So far, the inflatable robot arm isn\u2019t very fast \u2014 extending and retracting at a rate of about one foot per second, plus time to locate the apple, position itself and pluck the fruit. That amounts to one apple every 25 seconds. Humans can pick an apple about every three seconds, according to the university.<\/a><\/p>\n

The arm is designed to be used in modern apple orchards, where trellis systems<\/a> are used to train trees into shapes that are more productive and easier to access. <\/p>\n

\u201cThe design is capable of reaching the roughly 60% of apples that our collaborator growers estimate to be the cheapest and quickest to pick,\u201d the engineers say in the resulting research paper. <\/p>\n

With this kind of capability, an automated apple picker like this won\u2019t be replacing human workers any time soon, but it could help bridge the gap in farm worker availability.<\/p>\n
