Watch Robots Grow Food Without Farmers

Start-up Iron Ox created a fully autonomous farm in San Carlos, California. The hydroponic, indoor farm relies on two robots to plant, care for and harvest all its produce. One of the robots is 1,000 pounds and about the size of a car. It picks up the trays of plants and transports them around the greenhouse. A second machine, a robotic arm, is responsible for all the fine manipulation tasks, like seeding and transplanting. As a tray of plants matures, the mobile robot carries it to the processing area. H
