So much so that Spread is creating the world's first farm manned entirely by robots. Instead of relying on human farmers, the indoor Vegetable Factory will employ robots that can harvest 30,000 heads of lettuce every day.

Don't expect a bunch of humanoid robots to roam the halls, however; the robots look more like conveyor belts with arms. They'll plant seeds, water plants, and trim lettuce heads after harvest in the Kyoto, Japan farm. 

"The use of machines and technology has been improving agriculture in this way throughout human history," J.J. Price, a spokesperson at Spread, tells Tech Insider. "With the introduction of plant factories and their controlled environment, we are now able to provide the ideal environment for the crops."
