  • Robotic electrically powered infrared based thermal weed control system
    Patent number: 10750736
    Abstract: An electrically powered infrared based thermal weed control system. A housing has a downwardly facing chamber. At least one electrically powered infrared heating element is mounted within the chamber. A source of electrical power is electrically coupled to the electrically powered infrared heating element. A control assembly varies the electrical power to the electrically powered infrared heating elements and the heat generated for controlling undesired vegetation there adjacent using targeted infrared radiation emitted by the electrically powered infrared heating element.
