Introducing the Raspberry Pi Weed Burning Robot
The Raspberry Pi Weed Burning Robot is an ingenious solution for protecting your garden from unwanted plants. This AI-driven gadget utilizes concentrated sunlight to burn the roots of offending flowers and plants, effectively eliminating them from your green space.
Developed by Nathan from NathanBuildsDIY, this bot uses the power of the Raspberry Pi 3B+ to evaluate the territory, moving into position when it senses a weed. Once in place, the bot uses a custom-made lens to focus sunlight onto the plant, effectively burning its roots.
Build Your Own Raspberry Pi Weed Burning Robot
Nathan has provided a comprehensive video tutorial, along with the necessary schematics, wiring diagrams, and code. The Raspberry Pi 3B+ is the main component, but you could substitute it with a Raspberry Pi 4 or Raspberry Pi Zero 2 W if you’d like to save some money.
The Fresnel lens is essential for focusing sunlight, and Nathan has used a set of wheels and motors to control it. The other main component is the battery, which powers everything else. The entire system is securely held together by a custom wooden frame, and Nathan provides a bill of materials at the end of the video.
