  7. LITERATURE SURVEY

    The development of our agricultural robot and the idea used to implement them, started with he study of various papers.

    Designing, employing, and examining an autonomous multipurpose vehicle[1] with safe, reliable and

    economic operation. This autonomous vehicle goes through the crop lines of Agricultural land and performs duties that are tiresome and/or unsafe to the farmers. First, it's been prepared for spraying, but other configurations are also designed, such as: a seeding, plug system to reach the most notable area of the plants to execute different tasks (pruning, harvesting, etc.), and a truck to move the fruits, crops and crop waste products. The wheels of this robot are designed so that it can travel easily in soft and wet soil.

    An automatic robot for agricultural purposes[2]. As one of the styles of development on automation and cleverness of agricultural equipment in the 21st century, all types of agricultural robots have been explored and developed to apply lots of agricultural development in many countries. This bot carries out primary functions like picking, harvesting, weeding, pruning, planting, grafting. They developed a robot to perform various activities in farm like cutting and picking. Image processing is used to identify grass in the field and also the height of the crop. A container is used to place the cut grass and harvested crops. Pesticide spraying is also equipped in the robot.

    Improvement in agriculture techniques like automatic planting of seed products on ploughed land by using automatic robot[3]. A robotic vehicle having four tires and steered by DC motors was developed. The seed planting device is fixed on the automobile to seed the seed products in even manner. The device will cultivate the plantation by considering particular rows and specific column at predetermined distance depending on different seed products. The obstacle recognition is considered and sensed by an infrared sensor. The complete assemblage is driven by a 12V rechargeable battery pack. The battery pack can be recharged by using solar power which is also attached to robot. This robot can perform bed preparation, seed mapping, seed placement and reseeding operations.

    The design, development and the fabrication of the automatic robot [4] which can dig the ground, put the seed products, leveller to close the soil and sprayer to apply water, these complete systems of the automatic robot works together with the power supply and the solar powered energy. Steering operation of robot is done using rack and pinion mechanism. Relay switch regulates power input for motor. Obstacle detection is done using IR sensor. A lot more than 40% of the populace on earth selects agriculture as the principal occupation; lately the introduction of the autonomous vehicles in the agriculture has experienced increased interest.

    An automatic robot [5] capable of carrying out procedures like programmed seeding, irrigation, and fertilization. In addition, it provides manual as well as auto control. The primary component is ARDUINO that supervises the complete process. Currently, robots are significantly being built-into working tasks to displace humans especially to execute repetitive job. Seeding is main steps in farming. In this process seeding is carried out in every row of the farming plot. In irrigation process, the soil sensor is used for monitoring environmental condition. It checks this level and alerts the farmer, then gradually applies little bit of water to the planted seed in every rows of the farming plot. The fertilization process is identical to

    irrigation process however, many plants need fertilizers when the seed germinates and the seed starts to develop. The automatic robot works on solar technology.

    An automatic robot which targets employing all the farming process especially on onion crop [6] within a bot by using firebird V automatic robot. The fire bird V robot uses ATMEGA 2560 as master controller, ATMEGA 8 as slave controller, IR, gripper design and other accessories. The suggested system prototype is applied by selecting an area which taking into consideration the agricultural field of any sort of onion crop. The automatic robot picks up the planting area by using detectors and seed products to be planted in the related field using gripper set up of the automatic robot.

  8. METHODOLOGY

    The methodological procedure, circuit diagram and the block diagram are included in this section. The development of the agricultural robot consists of the integration of hardware techniques and software tools. Fig. 4 shows the blockdiagram of agricultural robot.

    Arduino Uno microcontroller is the master controller of the developed robot. All the operations of the robot are controlled through Bluetooth connectivity.The robot for agricultural purpose is an autonomous robot which is controlled remotely through a wireless Bluetooth connectivity between the Smartphone and the robot. The Bluetooth electronics app is used to control each and every operation of the robot. The Bluetooth HC-05 module is fixed on to the robot which receives signals from the Bluetooth electronics app and sends these signals to the microcontroller forprocessing of operations.

    The microcontroller is powered by a 12V DC battery and it consists of a voltage regulator, which is used to regulate the voltage input for the controller.The microcontroller gives a 5V supply to the driver circuit. This supply is insufficient to actuate DC motors. Thus driver circuit amplifies 5V current into 12V current and drives the motors connected to it.

    The L293D motor driver 1 circuit is used to control the bidirectional motion and receives signals from the microcontroller.The DC motors control wheel motion and other activities of the robot. The microcontroller sends signals like 00,01,10,11. When signals are like 00 or 11 then the motor is in off condition so there is no movement of robot occur, if else the signal like 01 then the motor will rotate on backward direction else the motor rotate on forward direction(when signal is 10).

    Figure 4: Block diagram of our model

    The L293D motor driver 2 circuit which controls two Dc motors. One DC motor is used for line marker and another one is used for seed dispenser. A line marker is used to mark a line along which seeds are dispensed. The marker has a single teeth and only one line is marked along the path of the robot. The depth through which the mark is done can be controlled through the Smartphone.

    The seed storage device is a cone like structure or a hopper in which seeds are stored for seeding purpose. The

    Special Issue – 2020

    hopper has a tube extension in its lower part and this hopper tube will allow seed to flow to the lower part of the robot i.e., for seeding position. Seeds from the hopper are dispensed for seeding through a seed dispenser. The seed dispenser assembly consists of a motor and a tube with a hole through it and is attached to the shaft of the motor. The dispenser tube is horizontally aligned inside the hopper tube. As the motor rotates the hole in the tube displaces. When the axis of the hole comes in contact with the axis of the hopper tube, a seed is dispensed. As the motor continues to rotate, the axis of the hole is displaced from the axis of the hopper tube. Therefore there is no seed dispensing. After the seeding operation, a leveler is used to close the soil and to level it.

    Three types of sensors are used in the robot; they are temperature sensor, humidity sensor and a soil moisture sensor. Temperature sensor is used to measures seed temperature. The humidity sensor measures the humidity content of air. The soil moisture sensors will measure moisture quantity in the soil and conditions of soil i.e., either wet or dry. The output signals from these sensors are displayed on the LCD screen.

  9. ADVANTAGES

    • With the help of innovative seed sowing equipment the seed can feed into the soil continuously without any restriction while in flowing of seed.

    • Most of seed sowing equipments machines mentioned require only one person to operate. Hence it reduces labour cost.

    • Overall Cost for seed sowing process will be reduced by using this seed sowing equipments.
