New ripeness detecting tomato-picking robot

Root AI, a start-up in Somerville, Massachusetts (U.S.), has unveiled first agricultural robot, dubbed the Virgo 1, which can pick tomatoes without bruising them, and detect ripeness better than humans.

The Virgo is a self-driving robot with sensors and cameras that serve as its eyes. Because it also has lights on board, it can navigate large commercial greenhouses any hour of the day or night, detecting which tomatoes are ripe enough to harvest. A “system-on-module” runs the Virgo’s AI-software brain. A robotic arm, with a dexterous hand attached, moves gently enough to work alongside people, and can independently pick tomatoes without tearing down vines.

The robot’s “fingers” are made of a food-safe plastic that’s about as flexible as a credit card, and easily cleaned. Josh Lessing, founder and CEO of Root AI, says that easy-to-clean trait is important.

“People don’t think about this -- you have to manage disease on a farm. Just as if I picked with my own hands, there’s a risk of spreading around mold, viruses or insects with a robot. That’s why you want these to be washable. It is part of the work you do to keep the plants safe.”

One of the most unique things about the Virgo, he notes, is that the company can write new AI software and add additional sensors or grippers to handle different crops. “It’s a complete mobile platform enabled to harvest whatever you need,” says Lessing.

In this way, the Virgo is a departure from other crop-specific harvesting machines on the market and in development, like Abundant Robotics’ apple picker, Agrobot’s strawberry picker, and Sweeper’s pepper-picker.

The Virgo has been tested at commercial greenhouses, including in the U.S. and Canada already.
