A realtime robotic weed control system was developed and tested in commercial cotton fields. The precision weedcontrol system was capable of distinguishing grasslike weeds from cotton plants and applying a chemical spray only totargeted weeds while traveling at a continuous speed of 0.45 m/s. The robot consisted of a realtime machine vision system,a controlled illumination chamber, and a precision chemical applicator. In commercial cotton fields, the system correctlysprayed 88.8% of the weeds while correctly identifying and not spraying 78.7% of the cotton plants while traveling at0.45 m/s.
