INTRODUCTION
Historically speaking a robot is used to be shaped like humans and referred to as machines and electric systems that were capable of performing similar actions as humans.
It is these robots play active roles in comic magazines, animations and science fiction.
Because they are artificially created, they are called “artificial man”.
And since they look like humans in appearance they are often called “androids” or “humanoids”.

This robot is controlled by an RF remote.
A control signal is transferred from transmitter end in the form of EMF waves or radio waves such that to control to the device remotely which is connected to the receiver end.
RF Module:
The RF module used here are STT-433MHZ transmitter,STR-433MHZ receiver.
They work in pairs meaning you need both receiver and transmitter to communicate with each other.
Receiver has 4 pins but we actually use 3 pins i.e. ground,vcc and one data pin.
RF ENCODER & DECODER:
We also use HT640RF encoder and HT648RF decoder.
It has a transmission enable line(TE).
When it is pulled high this cycle will repeat itself as long as the TE line is held high.
Once TE line falls low the encoder output completes its final cycle and then stops.
AT89S52 MICROCONTROLLER
In this project we use AT89S52 microcontroller.
AT89S52 is a low power, high performance coms 8 bit microcontroller with 4k bytes of In-system programmable flash memory.
It provides the following features:
4k bytes of flash
128 bytes of ram
52 input & output pins
2 data pointer.
This can be moved forward and reverse direction using greased motors of 60RPM.
This robot can take sharp turnings towards left and right directions.
Also wireless camera with voice & image transmission is interfaced to the kit.
By using microphone, commands given by the user will be recognition module.
