Development and autonomous navigation of a field robot

Published on May 23, 2016

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 and Agriculture Summit (April 27, 2016)

Published on Jun 6, 2016

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.

Robot waters plants

Published on Jun 10, 2016

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.

Eric the robot
July 5, 2016

A team of engineering students from Harper Adams University came second in a recent international robotics competition.
Four 5th year MEng Agricultural Engineering students made up the Harper Adams team at Field Robot Event 2016 in Gut Mariaburghausen in Ha?furt, Germany.
Eric, seen here, was the robot the team had created for their group research project.
