Crop producers are increasingly providing digital data to manage crop production on a more precise field scale. Crop and livestock monitoring by Unmanned Aerial Vehicles (UAV), and the imagery collected with these systems, will provide additional data sets to increase precision management practices and yields for farmers and ranchers and, simultaneously, provide more effective safeguards for the natural environment.
John Nowatzki is an agricultural machine systems specialist in the Department of Agricultural and Biosystems Engineering at North Dakota State University. His research uses Unmanned Aerial Systems (UAS) in crop and livestock applications to improve crop health and increase crop yields.
John is currently conducting applied research and University Extension programming in four areas: UAS applications to crop and livestock management, active optical sensor applications to field crop health, the impacts of soil compaction from wheel tracks on field crop yields, and the impacts of tree windbreaks on field crop yields.
This video presents the development and autonomous navigation in a row crop of a low-cost four wheel differential-drive field robot. The platform features a passive articulated suspension system, that allows the chassis to adapt to the soil's morphology and its four drive wheels to remain in contact with the substrate during obstacle climbing.
The vehicle's motion control system includes individual PID controllers for closed-loop regulation of the four wheels' velocity. The platform is equipped with various internal state sensors and perceives its external environment by using only one web camera, installed on a pan/tilt mechanism. The images acquired by the webcam are processed in real-time by an Odroid Single-Board Computer, implementing a fuzzy logic motion controller that allows autonomous traversing of a row crop.
The robot has been developed at the Control Systems and Robotics Laboratory of the Technological Educational Institute of Crete, in Heraklion, Greece.

Intelligent Machines will help humans flourish in a world that becomes more mindful of its resources. With this in mind, Comet Labs recently gathered a small group of roboticists, data scientists, academics, investors, and industry experts to discuss the ways in which robotics and AI can meet the needs of the agriculture industry, specifically in growing and harvesting perma and row crops. The event was hosted in partnership with Driscoll's, Naturipe, Yamaha Motor Company and Orange at Rackspace in San Francisco, CA.
The task gives the robot a green thumb, quite literally. The Multipurpose Mobile Manipulator can water houseplants in an indoor environment using a specialized hose adapter that pours water from an upside-down water bottle located on the back of the robot. It searches for houseplants using an ultrasonic rangefinder on the other hand. With enough development, this task can evolve into a full fledged autonomous gardening and farming machine, where the robot monitors, fertilizes, and waters a row of plants over time.
