ABSTRACTThe proposed technique is intended to facilitate the user
to access the Land Rover through Hand Gesture. It provides the
advantages of robust control, wireless control, system reset and
status display in LED. The control of robot involves three distinct
phases: reception, processing and action .generally, the receptor is
the accelerometer sensor receives the transmitted signal, processingis done by the on-board microcontroller according to tilt and
motion of the accelerometer or processor, and the task (action) is
performed using motors or with some other actuators.

POWER SUPPLY SECTION
Transformer - steps down high voltage AC mains to low voltage AC.Rectifier - converts AC to DC, but the DC output is varying.
Smoothing - smoothes the DC from varying greatly to a small ripple.
Regulator - eliminates ripple by setting DC output to a fixed voltage.

Introduction
The 3-axis Accelerometer measures bothstatic and dynamic acceleration of the body to which itis attached. In static acceleration it can measure the tilt,vibration and etc while in dynamic acceleration, it canmeasure the real time acceleration of motion of astructure to which it is attached. It gives 3 coordinatevalues x, y, z as its output.
Features Low cost with high quality.
Easy to get used to board with the best silk layer.
3-axis sensor(X, Y & Z-Axis). Small, Compact and Low Power.
In-built 3.3V supply.
Measures up to 3g.
1X6 Header for external connection.

Introduction The display used here is 16x2 LCD (Liquid
Crystal Display); this means 16 characters per line by 2lines. A very popular standard exists which allows us to
communicate with the vast majority of LCDsregardless of their manufacturer. The standard isreferred to as HD44780U, which refers to thecontroller chip which receives data from an externalsource (in this case, the Atmega16) and communicatesdirectly with the LCD. The 44780 standard requires 3control lines as well as either 4 or 8 I/O lines for thedata bus. Here we are using 8-bit mode of LCD, i.e.,using 8-bit data bus.

RADIO FREQUENCY TRANSMITTERIntroduction
RF modules are normally dividedinto three groups, RF transmitter module,RF receiver module and RF transceivermodule.
Transmitter module is aelectronic component using a variety ofradio signals to remote control the targetdevice which has a receiver module built-
in. The remote distance can bevery long and you don't need a line-of-sight remote controlling compared toremote controls using infared technology.

RADIO FREQUENCY RECEIVER:-
RF modules are normally divided into threegroups, RF transmitter module, RF receivermodule and RF transceiver module.
There are two types of RF receiver
modules: superheterodyne receiver andsuper regenerative receiver,superheterodyne has performanceadvantageover super-regenerative ones,
but also is more complicated and price is alittle higher.
The detailed explanation between thetwo types of receivers can be found here.
