"LettuceBot 2," a lettuce thinning robot created by Blue River Technology, turns around at the end of a row. LettuceBot 2 is equipped with wings that fold down, enabling it to thin 160 inches of lettuce at a time. LettuceBot 2 is the next generation of Blue River's precise field robotics technology, processing data and performing real-time thinning four times faster than its predecessor, "LettuceBot 1."

The food gap is becoming one of the world's biggest challenges. According to the United Nations, farmers must grow 70 percent more food by 2050 to feed the world's population. Founded in 2011, Blue River Technology is a small business in Mountain View, Calif., that's helping solve this challenge. The company merges robotics, computer vision and machine learning to change the way food is grown and to lift yields from every acre of farmland. Blue River's first technology, called LettuceBot 1, is a robot that intelligently and precisely thins lettuce fields.
Lee Redden, a National Science Foundation (NSF) principal investigator and a founder of Blue River, is leading a research team that's developing robots that use computer vision to recognize and identify the needs of plants and take appropriate action in real time, even in rugged agricultural conditions. For example, the robots can determine whether a crop needs thinning, then spray a killing agent with precision to rid excess plants and thin the field.
Funding from NSF's Small Business Innovation Research (SBIR) program (grant IIP 11-43463) played a key role in building a team and these machines. Blue River is now operating its precise field robotics as a commercial service and is beginning to develop new concepts that serve its vision: Advanced technology for better agriculture.
