3. Component Description
Arduino Uno
Arduino Uno is an ATmega 328p Microcontroller based prototyping board. It is an open
source electronic prototyping platform that can be used with various sensors and actuators.
Arduino Uno has 14 digital I/O pins out of which 6 pins are used in this project.
Fig: 1
HC-SR04
It is an Ultrasonic Range Finder Sensor. It is a non-contact based distance measurement
system and can measure distance of 2 cm to 4 meter.
Fig: 2
L293D
L293D is a typical Motor driver or Motor Driver IC which allows DC motor to drive on
either direction. L293D is a 16-pin IC which can control a set of two DC motors

4. simultaneously in any direction. It means that you can control two DC motor with a
single L293D IC.
Fig: 3
Servo Motor
The SG90 is a simple Servo Motor which can rotate 90 degrees in each direction
(approximately 180 degrees in total).
Fig: 4
IR Sensor Module
An IR sensor can measure the heat of an object as well as detects the motion.These types
of sensors measures only infrared radiation, rather than emitting it that is called as a
passive IR sensor. Usually in the infrared spectrum, all the objects radiate some form of
thermal radiations.

5. Gas Detector
This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG
(composed of mostly propane and butane) concentrations in the air. The MQ-6 can detect
gas concentrations anywhere from 200 to 10000ppm.
Fig: 6
IR Receiver
An infrared receiver, or IR receiver, is hardware that receive information from
an infrared remote to control the device.
Fig: 7
Bluetooth Module
Bluetooth is IEEE 802.15.1 standardized protocol, through which one can build wireless
Personal Area Network (PAN). It uses serial communication to communicate with devices. It
communicates with microcontroller using serial port (USART).
Fig: 8

6. IR Remote Control
Remote control is an electronic device used to operate the device from a distance
wirelessly.
Fig: 9
RF Control Module
An RF module (radio frequency module) is a electronic device used to transmit and
receive radio signals between two devices. In an embedded system it is often desirable to
communicate with another device wirelessly.
Fig: 10
Motors
A DC motor is any of a class of rotary electrical machines that converts direct current
electrical energy into mechanical energy.
Fig: 11

7. Battery
A battery is a device that produces electrons through electrochemical reactions, and
contains positive (+) and negative (-) terminals. A battery consists of one or more
electrochemical cells, which transform stored chemical energy directly into electrical
energy.
Fig: 12
Chassis
It’s basically the frame of the robot on which motors and wheels are mounted and all the
circuitry part is also placed on it.
