COMPONENTSCOMPONENTS

The whole project is divided into 3 parts:

1) Electronics Hardware

2) Software

3) Mechanical

Hardware SectionHardware Section

The hardware of the ACR consists of 2 parts: 1) Sensor part

2) Control Unit

SensorSensor

It consists of 2 infrared LED’s and 2 It consists of 2 infrared LED’s and 2 photodiode’sphotodiode’s

SensorSensor Infrared led’s are used as the transmitter of Infrared rays to the surroundings.

Photodiode’s are used as the receiver of the IR rays which are coming back after gets reflected from the obstructions.

Control UnitControl Unit

IC’s used in control unit: IC’s used in control unit:

1)1)LM324LM324

2)2)L293DL293D

3)3)4010640106

4)4)8051 Micro-controller8051 Micro-controller

IC LM324IC LM324

Consists of 4 independent operational amplifiers.

Operate from a single power supply.

Used to amplify the input signal.

IC L293DIC L293D

It is a quadruple half H driver IC.

Used to drive DC motors and stepper motors.

2 motors can be connected at the same time and operated simultaneously.

IC 40106IC 40106

8051 Micro-controller8051 Micro-controller

* The program is written in the program memory of the 8051. * It takes the input from the sensor and generate the proper signal according to the program.

Software PartSoftware Part

Software is written in the assembly language.

It is burned in the micro-controller IC using burner kit.

The micro-controller takes the input signals and interprets them according to the software written and gives instructions to the output ports.

Mechanical PartMechanical Part

This part consists of vehicle and DC motors.

VehicleVehicle

This part consists of the body of the ROBOT.

It consists of a vehicle with two DC motors which will be used to run the back tyres of the robot.

The two DC motors are interfaced to the 8051 microcontroller through IC 293D.

OutputOutput

Anti Collision Robot works in the following steps:

1)Power is switched on.2)Robot starts moving in forward direction.3)Sensor sends infrared rays.4)If any obstacle comes in its way.5)Photodiode detects IR rays which will be reflected from the obstacle.6)Robot stops immediately.7)Move a little backwards with a beep sound from the buzzer.8)Robot stops again.9)Turns towards its right direction.10)Then move in forward direction again.

AdvantagesAdvantages

Compact size.

Low cost.

Efficient in preventing collision.

Flexibility

Efficiency can be improved further.

Hardware and software can be upgraded easily.

ApplicationsApplications

Automobile industry for preventing the number of road accidents.

Used in a spy robot.

Used in automatic bomb detection robot.

Used by as remotely controlled robot for distant

locations such other planets like mars etc.
