2. ABSTRACT Developed agriculture needs to find new ways to improve efficiency. One approach is to utilize available information technologies in the form of more intelligent machines to reduce and target energy inputs in more effective ways than in the past. Precision Farming has shown benefits of this approach but we can now move towards a new generation of equipment. The advent of autonomous system. Architectures gives us the opportunity to develop a complete new range of agricultural equipment based on small smart machines that can do the right thing, in the right place, at the right time in the right way.

4. WORKING PRINCIPLE When the power is supplied to the 12v Dc motor, shaft and crank attached to the shaft start rotating. As the crank rotates the pin slides inside the yoke and also moves the yoke forward. When the crank rotates through in clockwise direction the yoke will get a displacement in the forward direction. The maximum displacement will be equal to the length of the crank. When the crank completes the next of rotation the yoke comes back to its initial position. For the next of rotation, yoke moves in the backward direction. When the crank completes a full rotation the yoke moves back to the initial position. For a complete rotation of crank the yoke moves through a length equal to double the length of the crank. The displacement of the yoke can be controlled by varying the length of the crank.

6. MOTOR An electric motor is an  electrical machine  that converts  electrical energy  into  mechanical energy . In normal motoring mode, most electric motors operate through the interaction between an electric motor's  magnetic field  and  winding currents  to generate force within the motor . In certain applications, such as in the transportation industry with  traction motors , electric motors can operate in both motoring and  generating or braking  modes to also produce electrical energy from mechanical energy . Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by  direct current  (DC) sources, such as from batteries, motor vehicles or rectifiers, or by  alternating current  (AC) sources, such as from the power grid,  inverters  or generators .

7. SOLAR PANEL In this project, we are getting a 5-10(Watts) output through solar panel. Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating. Solar modules use light energy ( photons ) from the sun to generate electricity through the  photovoltaic effect . The majority of modules use  water -based  crystalline silicon  cells or  thin-film cells  based on  cadmium telluride  or  silicon . The structural ( load carrying ) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Electrical connections are made  in series  to achieve a desired output voltage or in parallel  to provide a desired current capability.The cells must be connected electrically to one another and to the rest of the system.

8. ARDUINO UNO CONTROLLER The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which six can be used as PWM outputs), six analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. The Arduino Uno differs from all preceding boards because it does not use the FTDI USB-to-serial driver chip. Instead, it features the ATmega8U2 programmed as a USB-to-serial converter. Revision 2 of the Arduino Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode .

9. TEMPERATURE SENSOR The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range. Lower cost is assured by trimming and calibration at the wafer level.

10. ADVANTAGES Low cost and more efficient Energy efficient and eco-friendly Better result than automated system Works at much cheaper price Net Gross Production Increases High efficiency due to uniform water distribution . Piping reduced.

12. CONCLUSION This paper provides a brief review of research on the agricultural machine about future. This agricultural machine design and fabricated to facilitated the former to working in simplicity manner and improve productivity. In this machine we take all the six functions separately i.e. weeding, cutting, spraying and bird flying. This project is reduced worker availability and perform same job in a less human source. That project is acceptable in future by former community. This technology may improve the working skill in a field, if the former community will apply that. The machine is easy operating for small and large purpose. The agricultural robot performs the task such as weeding, cutting and spraying alternately and it reduce human efforts.It may become success our project accepted and used by former in a field.
