You can convert even some scrap into something useful and that is what i have done .
I was just cleaning my room and i got a robot lying alone in the scrap and then comes the idea of converting it into a useful robot and now it can run on four wheels and can play with a tennis ball .
Now i will tell the making of my robot so that you can also make it , it is quite easy.
The first thing i did was that i bought some material required to complete my process .Here i am giving the details of materials that i used in making my robot.
The Robot From The Scrap
This was the robot which i found from the scrap
SOME MATERIALS NECESSARY TO COMPLETE YOUR PROCESS
1. SOLDERING IRON
THE SOLDERDED WIRES WILL LOOK LIKE THIS
One will have to use a power supply to run the motors and the power supply will be given by using two 6V battery.
3.CIRCUIT USED TO RUN ROBOT USING SWITCH AND RELAY
RELAY :- Let me describe you what is a relay , a relay is something used to run high current devices or to control a device through a low power level.A simple relay has 5 pins .There are 2 coil pins ,1 pole pin ,1 normally connected and 1 normally open . Without the application of voltage the pole pin is always connected with normally connected pin and when you will apply voltage the pole pin will got connected to normally open pin.
CIRCUIT DESIGNED IN PROTEUS
It is always better to check the circuit before applying , this can be achieved by a software known as proteus and here is the circuit which i designed in this software .
Now see that all the normally connected pins and one coil pin of all the relay are connected to each other and to negative terminal of the battery .One pin of all the switches are also shorted and other pins of respective switches are connected to other coil pin .The normally open pins of all the relays are also shorted with each other and are connected to power supply through switches .when the above two switches are pressed normally open pin will get the voltage and then the pole pin will get connected to the open pin and the pole pin will also get voltage and the pole pins are going to the motors( which are connected to parallel ) and hence motors will get the power supply and runs .
The Final Robot
