INTERFACING THE ROBOT SYSTEM WITH COMMUNICATION MODULE BLUETOOTH
mca mini project topics 2019
Earlier methods used were: First, the use of an onboardcontrol system, which requires a human to control therobot/ machine by using onboard commands/buttons. Second,wired control system, which requires handling of bulkywires and limits the control length.Third, wireless dedicates remote system, requiredifferent remotes for various machines, prone todisturbance and can be hacked easily as there is notprotected transmission of signals, anyone with thefrequency can send commands.
Android application with robotics is an exciting areafor human computer interface that is used to assisthumans to control the mechanical system via software.Here, we designed an android application to control robot/machines wirelessly using a secured connection overBluetooth
The basic considerations for proposed segments are:Interfacing the robot system with communicationmodule Bluetooth (Embedded Hardware Model) Bluetooth Module with android application(Software Model). mca mini project topics 2019 The input from android application is processed usingcommand and understanding algorithms to parse intocontroller that will control the robot. A communicationprotocol that effectively translate the selected commandinto maneuverable tasks to any control board.

Driving MotorsA combination of four 100RPM motors (12V, 1A) with spurgearbox system are used to drive four wheels of the robot. 2.Arduino MegaArduino Mega 2560 based on ATmega 2560 is used as main brain of the hardware. It takes input from the sensors mounted on chassis. Suitable decision is made by Arduinoand actuators are governed accordingly for motionand implementing different selected operations. 3.Voltage Divider Voltage divider used here provides two voltage distribution one is 5V (for logic operations) and other is 12V (for motors). 4.TyresTread block tyres are used with 4.5” diameter for better gripping and push on landapplications. 5.Bluetooth Bluetooth gives connectivitybetween two devices using particular MACaddress. 6.Motor Driver (L298N based) Motor driver board based on L298N is used to drive the motors for motion.
