3. Programming an industrial robot by a typical teaching method,
through the use of the typical methods is a very time
consuming task and requires some technical expertise . In
industry, this type of robot programming can be justified
economically only for production of large number of products.
Hence ,new approaches to robot programming are required .
So we have got motivation to design an easy , less complex and
an efficient robot which is less expensive and does not need
technical expertise.
We have designed the robot using the concepts of the
ANNs(Artificial Neural Networks)& HMI(Human Machine
interface ).

4. Gestures are the natural form of communication. In robotics field work
has been done to identify and recognise human gestures.
There are various ways to capture sensors using the finger gesture
reorganisation system based on active tracking mechanisms.
As the keyboards and mouse provide a means of virtually all input. Use
of other option than mouse or key board are head and hand gesture
recognization.
So our robot uses the other method of inputs than the key board or
mouse .
The robot moves according to our hand gesture by recognising the
movement of our hand

5. As we require a setup for any of the thing we want to
design or make so we also have a set up for the project
we have made.
The experimental setup is shown in next slide:

10. The schematic circuit of the transmitter is given
below:-

12. Circuit Diagram this hand gesture controlled robot is
quite simple. As shown in schematic diagrams, a RF
pair is used for communication and connected with
AT89c52 to run the robot motor.
Motor driver’s input pin 2,7,10 &15 is connected to
AT89C52 digital pin number 21,22,23,24 respectively.
Here we have used two DC motors to drive the robot
in which one motor is connected at output pin of
motor driver 3 and 6 and another motor is
connected at output pin 11 and 14. A 12 volt battery is
also used to power the motor driver for driving
motors.

22. We have used three soft wares for making our project.
1. kicad for schematic diagram, for component net list and for
PCB lay out.
2. keil:- for writing , execution and compilation of program.
3. Protious 7.8 for simulation of our circuit . Provided by
labcenter electronics

23. While making this project we found some of the
problems :
1. Schematic diagram development
2. Wires get one over other while developing the PCB board
3. In shouldering

25. The current project can be modified in future for many
purposes .
We can modify it as a gesture recognised wheel chair
for persons with disabilities.
It can be used for detecting bombs and other
explosives
The future prospective diagram is shown in next slide.

The shown diagram is for the transmitter and receiver section. In transmitter section we have an accelerometer then followed by a comparator then an Encoder followed by an RF transmitter. The range of transmitter is 50 meters and is of 443 MHz.
Talking about our receiver part we have got an RF receiver connected to antenna then a Decoder (ADC) is there then cones our programmed micro controller followed by The DC motor driver IC to drive the motor.
This is image of our receiver robot which will move according to the command given by transmitter fixed in our hand.
The above image shown is a typical arrangement of transmitter circuit which remains in our hand and through which we give command to our robot.
The presented slide is circuit diagram for the transmitter section. Here the power supply gives a constant power of 5 volts, then the power comes to the accelerometer and then to the comparator to recognise the gesture and and to transmit the information to the receiver. The comparator IC is connected to the Encoder IC which is further connected to the transmitter of 443 MHz.
Now the given circuit is for receiver section 1st one is power supply(a bridge rectifier) the other is main circuit of receiver. The transmitted information is revived by the receiver then it is given to the decoder and after decoding the decoded digital information moves to the microcontroller which understands the information and gives the command to motor driver IC which drives the motor according to the given command.
This slidee shows the working of our robot as the table shows hand gestures and the input for AT89C52from the corresponding gesture. The table shows the side and the digital bits given to the microcontroller and shows how it moves.
This slide is about the main equipments that we have used in the robot .
Accelerometer(ADXL335):- works as sensor and is a major part of the robot transmitter, makes the robot move according to the hand movement.
it actually contains a liquid metal in so as we tilt our hand the liquid moves to the corresponding pin and conducts the current as data.
2.The next one is motor controller IC named as L293D. Used to drive the motor and the pin diagram is as given above. We can connect two motors to this IC and the motor moves according to the command given by this IC.
3.This side is for the Encoder IC (HT12E) which encodes the information and commands to be transmitted. The pin diagram is shown as.
4. This IC is known as decoder IC (HT12D) and it decodes the information at receiver side. The pin diagram is shown in figure.
Tis IC is known as constant voltage regulator IC named as LM7805 this gives us constant power of +5 volts. Has 3 pin input output and ground. Made up of Zener Diode.
This is the image of the microcontroller that we have used in our project it is named as AT89C52.
The given is the pin diagram of the microcontroller having 4 i/o ports, a vcc , a vss and other pins as shown in figure.
These are the software that we have used during making our project
These are the current opportunities for our project.
A typical image for the work we can do in future for helping disables. We wish to make a wheel chair which is conntrolled by our head gestures.
