Poop sensors, drones, and robots: Automation at the farm

At first, the horse that greeted press attendees at an October 20 occasion at Mount Vernon seemed decidedly analog. But as a Virginia Tech professor turned Mikey round, an uncommon little bit of know-how got here into view: a small field hooked up to a wrap round his tail.

The use case concerned poop.

“We’re in the middle of the data revolution,” mentioned Robin White, an assistant professor at Virginia Tech’s Department of Animal and Poultry Sciences and its Center for Advanced Innovation in Agriculture, earlier than explaining that this pod included sensors to detect the telltale motions of the horse going to the toilet.

“It seems like it might be an invasion of Mikey’s privacy,” she joked. But manure management issues at farms, the place extra information may assist to scale back their fertilizer functions and restrict runoffs into close by waterways.

White subsequent pointed to a much less apparent sensor hooked up to the horse’s bridle that recorded Mikey’s exercise and coronary heart charge.

“We’ll know when he’s resting and eating and when he’s perhaps playing in the field with his friends,” he mentioned. “We can improve management of their health.”

Low-stress handling may pay greater proceeds in cows and different “food animals,” as White put it, however horses make for simpler beta testers: “They’re so used to having devices attached to them.”

The smart-farming demo then moved open air to a discipline close to a recreation of the 16-sided barn George Washington designed to permit extra environment friendly threshing of wheat by horses treading on sheaves to separate the heads of grain.

Virginia Tech determined to stage these reveals at Mount Vernon not simply due to the photogenic surroundings, however due to its historical past of agricultural innovation below Washington, who was an early adopter of such practices as crop rotation and composting. Washington, nevertheless, may conduct these experiments with out having to pay the wages of enslaved staff, a reality made plain in today’s exhibits at Mount Vernon.

A number of ft from a row of kale in that discipline, a DJI Phantom 4 Pro quadcopter drone sat subsequent to a four-wheeled Clearpath Husky “field research robot” with a Lidar sensor mounted on high.

Hasan Seyyedhasani, an assistant professor of Automation and Connected Technologies in Virginia Tech’s School of Plant and Environmental Sciences, defined how two drones could possibly be higher than one in an agricultural context.

While farmers have been utilizing drones to test their crops for years now, his imaginative and prescient is to have robots working collaboratively. For occasion, aerial {hardware} like the DJI drone may use their colour or thermal cameras and highly-accurate real-time kinematic positioning GPS to supply intelligence for the Husky robotic on the floor, serving to it to collect extra up-close information and carry out duties like pruning or harvesting.

“We fuse these two sensing systems together to collect comprehensive information,” he mentioned. “Hopefully in the next five years we can have a real automated farm.”

But there’s nonetheless loads of room for enchancment in simply the data-gathering a part of drone agriculture. Another Virginia Tech researcher famous over electronic mail that he’s seen promising outcomes from utilizing a DJI drone outfitted with 4K cameras to examine grapes at the college’s research winery in Winchester, Virginia.

“Even in my small vineyards, I was able to find some information that could have been missed if I did not fly my drone,” he mentioned. But he complained that the software program he’d bought stored yielding misaligned photographs and wanted higher documentation.

Advancing to a state of agricultural automation by which drones lead different drones would require tackling many different issues. Battery life could also be the greatest amongst them; Seyyedhasani mentioned the Husky solely lasts two to 3 hours on a cost.

Bandwidth could be a fair greater impediment in lots of agricultural settings. A study launched in October by the Benton Institute for Broadband and Society, a Wilmette, Illinois, nonprofit, cited 2019 U.S. Department of Agriculture data displaying 22% of farms have been restricted to a digital subscriber line (DSL), a sluggish phone-based know-how; 18% relied on smartphones; 3% nonetheless limped alongside on dial-up entry; and 18% had no web connectivity at all.

But the promise of utilizing drones and robots to amplify a farmer’s senses—in impact, returning a hands-on stage of care to industrial-scale farming—stays actual. As White put it: “We have the opportunity to leave those animals in an environment as natural as possible and still understand their day.”
