These May Be The Droids Farmers Are Looking For

When it comes to farm robots, fruit gets all the attention. But it looks like trees and shrubs could win the prize for first significant agricultural market for small mobile robots.
Massachusetts startup Harvest Automation is beta testing a small mobile robot that it’s pitching to nurseries as the solution to their most pressing problem: a volatile labor market.
The multi-billion-dollar industry that supplies ornamental plants to building contractors, big-box retailers and landscaping firms — $11.7 billion according to the most recent USDA figures — has been eagerly awaiting automation for decades. The down economy and harsh state laws targeting undocumented workers have turned up the pressure.
The horticulture industry has caught the attention of several robotics industry veterans, including Joe Jones, a co-inventor of iRobot’s Roomba vacuum cleaning robot. What they see is an opportunity to develop a small, relatively inexpensive, mobile material handling robot. Their venture-backed company has been field testing the robots at 11 nurseries around the country, and plans to release its first product at the end of the first quarter or beginning of the second quarter next year.
Harvest Automation bootstrapped the development of prototype robots and received its seed funding from its customers, said CEO Charles Grinnell. The company landed $5 million in venture capital funding from Life Sciences Partners, the Midpoint Food & Ag Fund, and the Massachusetts Technology Development Corporation.
In today’s human-tended nurseries, immature potted trees and shrubs arrive at nurseries by truck and are offloaded onto the ground. Teams of migrant workers — undocumented for the most part — spread the plants out one by one following markers outlining a grid. When the plants are ready to be shipped out later in the season, workers reverse the process to group the plants for loading onto trucks. “We’ve recognized the need for robotics in the nursery industry for moving pots because it’s one of our highest concentrations of labor use,” said Tom Demaline, president of Willoway Nurseries, Inc. in Avon, Ohio.
Ten years ago the Horticulture Research Institute took a crack at automating nurseries, said Demaline. “The whole concept there was building a bigger machine to do the process, but it just never worked that well,” he said. When Harvest Automation showed Demaline it’s small mobile robots, the lightbulb went on, he said. “It was stark simplicity,” he said. “The robots were more adaptable to a wider range of growing areas.”
Small mobile robots that tend crops are just emerging, and most of the action is in produce. Row crops provide a semi-structured environment, and several companies are marketing four-wheeled robots with computer vision systems that monitor and in some cases tend to crops. The most advanced are medium-sized strawberry-picking robots, notably a machine from Spanish firm AgroBot. One player in the nursery automation market is British firm CMW Horticulture Ltd., which sells a medium-sized pesticide-spraying robot for greenhouses and nurseries.
Farmer’s little friend
The Harvest Automation robots are knee-high, wheeled machines. Each robot has a gripper for grasping pots, a deck for carrying pots, and an array of sensors to keep track of where it is and what’s around it. Teams of robots zip around nursery fields, single-mindedly spacing and grouping plants. Think Wall-E without the doe eyes and cuddly personality, or the little forest-tending ‘bots in the 1972 sci-fi classic Silent Running.
