The main aim of this project is to design an electronic system improves different agriculture processes like grass cutter and pesticide spray which is controlled from android Bluetooth application using mobile phone and is less harmful to the environment as well as to humans. This bot can be easily controllable from android Bluetooth application. The bot sprinkles the pesticides, covering all plants on the farm. With this robot's help, the farmer's time and work will be reduced. Solar energy is stored into the rechargeable battery through charging circuit and this battery power is used to control robot DC motors. The controlling device of the whole project is PIC Microcontroller. The microcontroller moves the robot motors in forward, backward, left and right directions with the help of DC motors which is interfaced to the microcontroller along with l293d motor driver. There is one more motor which is interfaced to the microcontroller with relay driver and which uses to cut the grass and switch ON the pesticide motor. To perform the task, Microcontroller is loaded with an intelligent program written in embedded ‘C’ language.    

The main objectives of the project are:  

• Designing of a multi applicable Agriculture bot.
• Using Bluetooth application to control the robot along with grass cutter and pesticide spray.
• To perform this task, Microcontroller is loaded with an intelligent program written in embedded ‘C’ language.
• Design of Solar based battery charging circuit.
