This robot shakes flowers to pollinate them when bees can’t

Out in a subject, tomato vegetation are pollinated both by wind shaking flowers or by bees, which fly into the flowers and vibrate, releasing the pollen into the air. However inside a greenhouse or indoor vertical farm, the place there are not any bees or wind, tomato vegetation want slightly assist—and shortly, that assistance will arrive in some greenhouses in West Virginia within the type of a six-armed robot known as StickBug.

The StickBug, a challenge from researchers at West Virginia College with funding from the U.S. Division of Agriculture, will use pc imaginative and prescient algorithms to map out indoor environments and study the place flowers on the vegetation are, and which flowers want to be pollinated. Then it should attain out its arms to pollinate these flowers. “There may doubtlessly be coordinated motion” utilizing a number of arms, says Yu Gu, an engineering professor at WVU main the group engaged on this challenge. “Say if a flower is behind a department, it may have one arm transfer the department away, and one other pollinate.”

That’s a difficult motion from a robotics standpoint, however that’s a part of the purpose of the four-year challenge. “Quite a lot of that is for advancing robotics as a lot as enhancing agriculture,” Gu says. The challenge acquired $750,000 in funding from the Division of Agriculture by the National Robotics Initiative.

The work on StickBug builds off of Gu’s earlier work on a robotic pollinator known as BrambleBee. That robot pollinated blackberries and raspberries, and was developed as a proof of idea that robots can do precision pollination (“We’re making an attempt to, like an insect, get in every flower,” Gu says) and never solely pollinate by broadly blowing air or shaking vegetation, like different machines utilized in indoor farming.


The StickBug challenge will sort out a few of the better robotic challenges with pollinating, like rushing up the method so it could possibly meet manufacturing necessities. Whereas BrambleBee had only one arm, StickBug’s six appendages have the flexibility to pollinate extra flowers on the identical time. The StickBug challenge may even work with growers, who might not have specialised information of robots. Gu and his group need to develop a low-cost robot that growers can simply settle for into their course of. And whereas the BrambleBee targeted solely on bramble vegetation, this challenge will examine how nicely the robots can pollinate tomatoes, an necessary financial crop that flowers year-round, in addition to blackberries.

There are a number of causes growers may have a robot to assist them pollinate their crops. One is the decline of bees, that are at present struggling within the face of colony collapse dysfunction, dangerous pesticides, and local weather change. However there are additionally sure locations bees don’t like, or locations they can’t actually exist. “There’s a concern about bee scarcity, which is actual,” Gu says, including, “there are plenty of agriculture settings not pleasant to bees,” like growth chambers or the rising world of indoor vertical farming. “These aren’t locations designed for bees to be fortunately residing in, so we’re hoping to sort out these environments.”

Gu sees robotic and bug pollinators each being very important to growers sooner or later, relying on the setting or time of 12 months. “We’re not all in favour of taking away bees’ jobs, and we would like bees to be comfortable,” he says. “However there’s additionally room for technological innovation. They will coexist, and so they can all convey advantages to society.”
