Automation has always been a big part of agriculture, from the first seed drills to modern combine harvesters. Farm equipment is now regularly outfitted with sensors that use machine learning and robotics to identify weeds and calculate the amount of herbicide that needs to sprayed, 1 , or to learn to detect and pick strawberries.
Lately, smaller, more delicate robots have 2 in droves. The TerraSentia is among the smallest of the farmbots 3 today. At 12.5 inches wide and roughly the same height, the 30-pound robot 4 well between rows of various crops. It also 5 gather data from much earlier in the agricultural pipeline: The research plots where plant breeders select the varieties that 6 make it to market.
The data collected by the TerraSentia is changing breeding from a reactionary process into a more 7 one. Using the robot's advanced machine-learning skills, scientists can check the influence of hundreds, even thousands, of factors on a plant's future traits, much like doctors utilize genetic tests to understand the 8 of a patient developing breast cancer.
The 9 on agriculture are rising globally. The human population is 10 to climb to 9.8 billion by 2050 and 11.2 billion by 2100, according to the United Nations. To 11 the world, farmers will need to augment their technological intelligence.
The agricultural giants are interested. Corteva has been testing the TerraSentia in fields across the United States. "There's definitely a niche for this kind of robot," said Neil Hausmann, who oversees research and development at Corteva. "It 12 standardized , objective data that we use to make a lot of our 13 . We use it in breeding and product advancement, in deciding which product is the best, which ones to move forward and which ones will have the right 14 for growers in different parts of the country. "
But some experts 15 whether such robots will ever truly be 16 to small farms, or a sufficiently affordable option. "For the kind of agriculture that smallholders tend to 17 , particularly in sub-Saharan Africa, there are a lot of barriers to the 18 of new technologies," said Kyle Murphy, a policy and agricultural development analyst. He 19 that robots like the TerraSentia may be more likely to help smallholder farmers indirectly, by 20 the development of better or more suitable crops.
