Design And Fabrication of Solar Powered Smart Ground Marking and Grass Cutting Machine

There are various types of tools used by contractors to create marking lines, both automatically and manually. In this modern age, most contractors use machines to save time. However, the high cost of purchasing machines restricts line marking work, especially in educational institutions. Based on observations, educational institutions face some problems while doing line marking work. The manual process of refilling the marking medium takes a lot of time. In addition, old marking tools are difficult to operate, especially for unskilled operators dealing with large-scale marking products, and they are difficult to carry due to their large size. The objective of this project is to design and fabricate tools that can facilitate the marking process, along with a smart grass cutting application. These tools will be affordable for commercial use. The automating lawn cutter is a semi-automated grass cutting vehicle that includes ground marking, powered by solar energy and capable of avoiding obstacles. The grass cutter and vehicle motors are interfaced with a controller that controls the working of all the motors. The controller moves the vehicle motors in a forward direction in case no obstacle is detected. On obstacle detection, the ultrasonic sensor monitors it, and the microcontroller stops the grass cutter motor to avoid any damage to any object, human, or animal. The microcontroller then turns the robotic as long as it gets clear of the object, and then moves the grass cutter, along with marking features, in the forward direction again.
