Weed and Feed Competition 2019

WEED & FEED COMPETITION 2019: May 17th, 2019

Location: Purdue University, ACRE, West Lafayette, IN

The Weed and Feed Competition challenges teams to create an autonomous machine capable of navigating a corn field to identify the corn crop and weeds. Upon identification of the corn plant, the machine should determine if the plant is healthy or in distress, requiring fertilizer to be applied by the machine. Upon identification of a weed, the machine should eradicate the weed chemically and/or mechanically. Teams may use a variety of solutions, combining elements of solutions in different markets and/or creating innovative solutions designed for their machine.

Contact agbotchallenge@gmail.com for details on submitting a proposal to compete.

Site Conditions:

  • Silty clay loam with conventional tillage (sod if too wet for tilled soil)
  • Corn height 6-12 inches, weed height 6-12 inches
  • 30 inch rows, turn radius at end 60 feet


Objective: Produce an unmanned, autonomous machine that will achieve the following goals. Teams will be scored in Mechanics, Software, Innovative Solution, and Execution

GOALS Mechanics Software Innovative Solution Execution
Autonomously maneuver two or four 150-ft rows at a time and autonomously turn at each end. The agBOT shall make two 150-ft passes. TBA TBA TBA TBA
Autonomously observe crop plants to assess health of the corn plant TBA TBA TBA TBA
Autonomously deliver fertilizer to distressed corn plants TBA TBA TBA TBA
Autonomously identify three common weeds within and between rows: giant ragweed, cocklebur, and foxtail TBA TBA TBA TBA
Arrange for weed to be destroyed either chemically or mechanically as the agBOT moves through the field TBA TBA TBA TBA
Provide real time observation methods of movement, plant identification, fertilization, and/or treatment of plants back to the base station TBA TBA TBA TBA

*More details To Be Announced (TBA)
