The main aim of the project is to design a multipurpose agriculture robot which can be run with a battery power for performing major agricultural operations like plough, watering and seed sowing. Android is a software stack for mobile devices that includes an operating system, middleware and key applications. Android boasts a healthy array of connectivity options, including Wi-Fi, Bluetooth, and wireless data over a cellular connection (for example, GPRS, EDGE (Enhanced Data rates for GSM Evolution) and 3G). Android provides access to a wide range of useful libraries and tools that can be used to build rich applications. Bluetooth is an open standard specification for a radio frequency (RF)-based, short-range connectivity technology that promises to change the face of computing and Wireless communication. It is designed to be an inexpensive, wireless networking system for all classes of portable devices, such as laptops, PDAs (personal digital assistants), and mobile phones. We can control the robot as well as water motor along with seed drop motor using android mobile phone through Bluetooth. Two DC motors along with L293D motor driver is used to move the robot. There is also a third motor interfaced to the microcontroller. Whenever that third motor is rotating automatically the pipe attached to the motor also rotates. There is a hole on the pipe. Only when the hole comes downwards, the seeds drop outwards. We put a funnel in fixed position above the holder arrangement on the pipe. Now when the pipe is rotating, there is point of time at which the hole comes downwards, exactly at that point of time, funnel gets arranged through holder. The seeds in funnel fall down through the hole. Here relay works as a switch to ON/OFF the seed drop motor and water motor. Plough tool is attached to the robot, when the robot moves it can be done automatically. The main controlling device of the whole project is PIC microcontroller to achieve the task.

 

The main objectives of the project are:

• The seed sowing mechanism is modified into simple mechanism.
• Wireless control of agriculture vehicle.
• The multipurpose agriculture vehicle is designed for small farmers in future.
• Wireless controlling of seed drop mechanism and water pump.
• Using android mobile to control the whole system and vehicle.
• Using Bluetooth for wireless communication.

The major building blocks of this project are:

• PIC Microcontroller.
• Rechargeable Battery.
• DC Motors along with L293d Driver.
• HC-05 Bluetooth.
• Crystal Oscillator.
• Reset Button.
• Relay with seed drop motor.
• DC motor with plough tool.
• LED Indicators.
• Plough tool.

Software’s used:

1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Micro controller.
3. Express SCH for Circuit design.
4. Bluetooth application.
