Development of Solar-Powered Herbicide Spraying Robot Controlled Using a Mobile Application

The evolution of digital agriculture is significantly influenced by agricultural robots, which contribute uniquely and present numerous benefits to the efficiency of farming operations. The trend of population explosion that the world is experiencing mandates the need to provide an adequate food supply. Hence, a conscious effort must be taken to eradicate weeds on the farmland. This research explored the use of technology to implement a weed elimination system by combining IOT and wireless navigation while also implementing solar energy which encourages green energy initiatives. The research encompasses an unmanned ground vehicle driven by four wheels and controlled by a mobile application that establishes a Bluetooth connection with the system. The ground vehicle was tested to establish the solar charging efficiency, the mobile application connection and operation and the ground vehicle spraying action. The result obtained at the end of the research showed that remote controlled operation of agricultural robots can help improve production efficiency while also reducing environmental pollution with solar charging systems.
