Bluetooth Based Agrobot Used to Spray the Pesticides

Abstract

Abstract: The agricultural robot, or Agrobot, that was created here is meant to spray pesticides on the crops. The purpose of a Bluetooth device is to enable mobile phone remote control of a robot. Because it is dangerous for people to be close to the sprayer when deadly chemicals are being sprayed over agricultural fields, this remote-operated sprayer was created so that it can be used from a safelocation. For wireless communication across short distances, there is a protocol called Bluetooth. A cell phone can be used to control agricultural equipment including machines for spreading urea, sowing seeds, and pulling weeds with the use of a Bluetooth device connectedto an embedded system. This straightforward technique is made to spray liquid pesticides in this regard. As a machine control unit that receives command signals from the mobile phone, the Bluetooth device interfaced with embedded systemis created. The moving mechanism is covered with this control circuit, its power supply, rechargeable batteries, and other devices, including DC motors. This mechanism can be controlled using a cell phone using an android application or an app placed on any smart phone. With the aid of this programme, users can wirelessly send commands through Bluetooth to the control system. The robot's movement can be controlled by a Bluetooth device connected to an 89C51 microprocessor chip. The mechanism is moved by two DC motors that are each individually controlled by an H Bridge IC.When necessary, liquid pesticide can be sprayed from the vehicle holding a small liquid tank over its chassis using a liquid pumping motor attached to the tanker's body. This pumping motor is likewise operated by the same cell phone.
