“Blue River is an ideal work place for engineers looking for a startup environment that also has the means and scale of a well-established company.”

Blue River focuses on applying machine learning, robotics, and computer vision technology to agricultural equipment that will in turn help farmers in making better decisions. Their primary product, See & Spray, uses computer vision, machine learning, and advanced robotic technology to distinguish between crops and weeds — and then spraying only the weeds.

Agriculture spraying drone can replace the traditional pesticide sprayer and it's speed is 40times of the traditional sprayer. It will save 90% water and 30%-40% pesticide. Small droplet diameter make the pesticide more well-distribute and improve the effect.

Sensors used in the agricultural drones are:

• Visual sensors
• Multispectral
• Thermal
• hyperspectral
• LIDA
