US vertical farming giant AppHarvest Inc has bought up Root AI, an artificial intelligence farming start-up that provides intelligent robots to help manage high-tech indoor farms.
Following the US$60 million purchase, Root AI and its robotic universal harvester, Virgo, will now provide AppHarvest with a baseline of harvesting support, working alongside crop care specialists focused on more complex tasks, across its network of vast indoor farms, based in the Appalachia region, which produce beefsteak tomatoes and tomatoes on the vine.
AppHarvest anticipates a game-changing advantage from its acquisition of Root AI’s technology – and in particular in the data collected by the robots as they harvest, which can help evaluate crop health, precisely predict yield and optimise overall operations of the controlled environment agriculture (CEA) facility.
Virgo is the world’s first universal harvester, which can be configured to identify and harvest multiple crops of varying sizes including tomatoes, peppers, cucumbers and more delicate fruits such as strawberries among others.
Though Virgo can work indoors or out, the robot’s focus has been on controlled environment agriculture. Over the past three years, it has collected the world’s largest data set of tomato images to enable it to identify more than 50 varieties in multiple growing environments and at varying stages of maturity to learn how and when to harvest.
Virgo uses a set of cameras combined with an infrared laser to generate a 3D colour scan of an area to determine the work it can perform. Once it maps the tomatoes or crop in question, it assesses their orientation and determines if they are ripe enough to pick. The robot can be programmed to make other quality assessments as well. The scan enables the robot to find the least obstructive and fastest route to pick the crop ahead of the arrival of the robotic arm and gripper. The robot can identify hundreds of tomatoes in a fraction of a second without having to connect to the cloud.
Virgo keeps score on its success rate like a video game. A built-in feedback mechanism constantly evaluates its efficiency so it learns how to harvest any given configuration of fruit most effectively.
Gathering more data through AI also enables growers to use real-time information to improve a number of sustainability efforts such as detecting and eliminating pests naturally, helping indoor farms successfully grow chemical pesticide-free fruits and vegetables.
“Farming as we’ve known it is broken because of the increasing number of variables such as extreme weather, droughts, fire and contamination by animals that make our food system unreliable,” said AppHarvest Founder & CEO Jonathan Webb. “Indoor farming solves many of those challenges, and the data gathered can exponentially deliver more insights that help us predict and control crop quality and yield. One of the key challenges in agriculture is accurately predicting yield. Many downstream decisions from work scheduling to transportation to retail planning are based on that. Any deviation between projection and actual yield can result in fire drills for numerous functions to adjust for the change, and AI can help solve that.”
Root AI co-founder and CEO Josh Lessing has now assumed the role of chief technology officer for AppHarvest, where he will take the lead in continuing to develop the robots and their AI capabilities for the network of indoor farms that AppHarvest is building.
Lessing, along with co-founder Ryan Knopf, who will join AppHarvest as VP of technology, helped establish Root AI as an early leader in employing artificial intelligence in CEA: “A piece of food – whether that’s a tomato or a berry or a cucumber – is an outcome from many variables that are part of the growing process,” explained Lessing.
“Enhanced data collection for each plant through the robot can lead to insights that teach us precisely how to design better, more resilient food systems that are reliable and that produce more food with fewer resources,” he continued. “Joining forces with AppHarvest is a natural fit: we want to ensure a stable, safe supply of the nutritious and healthy food that people should be eating – grown sustainably – and doing that at the scale of AppHarvest gives us the opportunity to make the greatest difference.”
Founded in 2018, Root AI is based in Somerville, Massachussetts, and has 19 full-time employees, all of whom are expected to join AppHarvest’s technology group to help advance the mission of building a resilient and sustainable food supply.
