The project “Agriculture Robot Controlled from Mobile Phone” aims to develop a multifunctional robotic system that enhances agricultural efficiency by automating tasks such as grass cutting and pesticide spraying. The robot is wirelessly controlled using an Android Bluetooth application, allowing the farmer to operate it remotely through a mobile phone. This system not only simplifies field operations but also minimizes human exposure to harmful chemicals, making it safer and more environmentally friendly.

The robot’s movement—forward, backward, left, and right—is controlled through DC motors driven by an L293D motor driver, interfaced with a microcontroller. Additional motors are used to operate the grass cutter and pesticide sprayer, controlled via a relay driver circuit. By integrating these functions, the system reduces manual labor, saves time, and increases operational accuracy in farming tasks. This mobile-controlled agricultural robot provides an efficient, cost-effective, and user-friendly solution to support modern smart farming practices.

       

The main objectives of the project are:  

 To design and develop a mobile-controlled agricultural robot using Bluetooth technology for easy and wireless operation.

 To automate grass cutting and pesticide spraying processes, reducing manual effort and human exposure to harmful chemicals.

 To utilize a microcontroller-based control system for efficient coordination of motors and relay-driven mechanisms.

 To ensure multi-directional movement (forward, backward, left, right) for flexible operation across different farm terrains.

 To create a cost-effective and user-friendly system that supports small and medium-scale farmers.

 To minimize time, labor, and environmental impact through automation and precise control.

 To promote the use of smart agricultural technologies for improving productivity and sustainability in farming practices.
