INTRODUCTION OF ROBOTS

Robots are re-programmable, multi-functional

devices.

Automation technology is used.

Mainly used in industries, aeronautics, armyapplications.



INTRODUCTION In our project the robot are designed to move

according to the command given by the user.

We are using RF transmitter to control the robot.

In the Robot we are using RF receiver to receive thecommands given by the user and acts accordingly.

It will move all the direction like forward, reverse,right and left.

Sense the object & human beings send the signal tothe PIC.

HARDWARE AND SOFTWARE HARDWARE

REQUIERMENT

Robot mechanism

Motors

Microcontroller unit

Sensing circuits

RF transmitter and RFreceiver

Buzzer

SOFTWARE REQUIREMENT

Embedded C programming

Keil cross compiler



PIC FEATURES

Operating voltage:4.0 - 5.5 volts

35 single word instructions

Operating speed:20Mhz, 200ns instruction

cycle

15 Interrupt sources



POWER SUPPLY

TRANSFORMER - step down the 230 V

RECTIFIER - AC TO DC conversion

FILTER - It reduce the noises

REGULATOR - It regulate the voltage

TRANSFORMER RECTIFIER FILTER REGULATER



DRIVER CIRCUIT The PWM(Pulse Width Modulation) function of PIC is used

for the electric current control to drive a motor.

It detects and controls the rotational speed of the motor. When lower than the specification speed, it increases a

control electric current. With the circuit this time, I used a motor for the speed

detection apart from the main unit motor.



ABOUT SENSORSIR SENSOR:



HUMAN SENSOR



RF TRANSMITER & RECEIVER



FUTURE OF ENHANCEMENT Instead of power supply solar panel can be

used.

We can add more number of sensors. Web camera or wireless camera can be fixed

on the mechanical model.

In driver circuit FET can be used to increasespeed and gain.



APPLICATION

It can be used in earth quake occurred areas.

Used in military applications.

We can survive the places where humanbeings can not enter.
