Conclusion

INTRODUCTIONA Gesture Controlled robot is a kind of robot which

can be controlled by your hand gestures not by old

buttons. You just need to wear a small transmitting

device in your hand which included an acceleration

meter. This will transmit an appropriate command to

the robot so that it can do whatever we want.

How Gestures Control Work?

The user just needs to

wear a small transmitting

device on his hand

movement of the hand in a

specific direction will

transmit a command to the

robot which will then move

in a specific direction.

This Project based on hand controlled assistsystem, developed using an electronic andmechanical arrangement controlled by aProgrammable Interface Controller.

BLOCK DIAGRAM

• Accelerometer placed on the hand sensed the tilt madeby the hand.

• Accelerometer capable of measuring how fast the speedof object is changing.

• This tilt corresponded to the analog voltage.

• Using this voltage, control signals are generated for fourdirections of the robot car.

COMPONENTS

USED

Accelerometer

An Accelerometer is a kind of sensor which gives

an analog data while moving in X,Y,Z direction or

may be X,Y direction only depends on the type of

the sensor.

Microcontroller

A microcontroller is a functional computer

system-on-a-chip. It contains a processor,

memory, and programmable input/output

peripherals.

Microcontrollers include an integrated CPU,

memory (a small amount of RAM, program

memory, or both) and peripherals capable of input

and output.

Various Microcontrollers INTEL

L293D L293D is a dual H-bridge motor driver integrated

circuit (IC). Motor drivers act as current amplifiers

since they take a low-current control signal and

provide a higher-current signal. This higher current

signal is used to drive the motors.

Two DC motors can be driven simultaneously, both

in forward and reverse direction.

Wide Supply-Voltage Range: 4.5 V to 36 V

High-Noise-Immunity Inputs.

Motors A machine that converts DC power

into mechanical power is known as aDC motor.

Its operation is based on theprinciple that when a current carryingconductor is placed in a magneticfield, the conductor experiences amechanical force.

DC motors have a revolvingarmature winding but non-revolvingarmature magnetic field and astationary field winding or permanentmagnet.

Different connections of the field andarmature winding provide differentspeed/torque regulation features.

The speed of a DC motor can becontrolled by changing the voltageapplied to the armature or bychanging the field current.

RF Module (Rx/Tx)

Radio frequency (RF) is a rate of

oscillation in the range of about 3

KHz to 300 GHz, which corresponds

to the frequency of radio waves, and

the alternating currents which carry

radio signals.

Although radio frequency is a rate of

oscillation, the term "radio frequency"

or its abbreviation "RF" are also used

as a synonym for radio – i.e. to

describe the use of wireless

communication, as opposed to

communication via electric wires.

The RF module is working on the

frequency of 315 MHz and has a

range of 50-80 meters.

HT12E(Encoder IC)

Operating voltage: 2.4V~5V for the HT12E

Low power and high noise immunity CMOS

technology

Low standby current: 0.1A (typ.) at VDD=5V

HT12A with a 38kHz carrier for infrared

transmission medium.

Minimum transmission word: Four words

HT12D(Decoder IC)

Operating voltage: 2.4V~12V

Low power and high noise immunity CMOS

technology

Low standby current

Capable of decoding 12 bits of information

Binary address setting

Received codes are checked 3 times

Address/Data number combination:

8 address bits and 4 data bits

Advantages

Traditional interfaces, keyboards and mice present a

bottleneck in application that rely on heavy

interaction of the user with the machine due to the

unnaturalness of the interaction.

From reading lots of related articles, we have learnt

that recent efforts have attempted to eliminate this

bottleneck by developing different ways of interacting

with computers, for example: speech, handwriting

Application

Gestures can be used to control interactions for

entertainment purposes such as gaming to make

the game player's experience more interactive or

immersive.

Through the use of gesture recognition, remote

control with the wave of a hand of various devices

is possible.

Industrial application for trolley control,lift control,

etc.

Military application to control robotics.

Medical application for surgery purpose.

Construction application.

This Technology advances in computing, sensor devices, materials and processing/classification techniques will make the next generation of this devices cheaper, more powerful, versatile and more ubiquitous.
