Protecting your garden from unwanted plants and excess weeds is half of the gardening process. One maker and developer, aka Nathan from NathanBuildsDIY, has taken the matter to an entirely new level by developing this impressive Raspberry Pi-powered solution. After deliberating potential avenues, he settled on creating an AI-driven robot that identifies weeds before using a Fresnel lens to concentrate light from the sun onto the weeds until they burn.
The system consists of a large wooden frame that can be wheeled up and down paths in your garden. It has a camera for observing the territory that the Pi evaluates for potential weeds. Once an unwanted plant is spotted, its Fresnel lens is moved into position while the machine waits until the weed is sufficiently burned.
