HOW TO MAKE A RC ROBOT CAR
Through this post you can, step by step, learn how to make a simple Remote Control Car that operates in RF (radio frequency). This is a very simple and beginner level robotic project which can be made by anyone with interest. All you need to know is the working of all integrated circuits (IC) and modules used in this robot. And there is absolutely no programming required for making this robot!
This is not exactly a robotics project. By definition, a robot is something that makes a decision based on some external parameters. But it is still something to start with.
Thing you will need:-
|Chassis: It is the base frame of the car.|
|L-Clamps (motor mount)|
|Castor Wheel DC Motor|
And in terms of electronics, you will need the following major components. You may also need some other basic components such as resistors and capacitors but we will discuss them as and when we get it.
RF Transmitter (Can be ordered online
along with RF receiver with cost around
|An encoder(HT12E)-decoder(HT12D) pair ( Can be ordered online|
with cost around Rs. 200)
|Motor Driver (Can be ordered online with|
price around Rs. 70-90)
|Tactile Switch (Can be ordered online at very low price)|
Here we will use a couple of ICs and a motor fixed to a chassis to make a remote control car. The brief idea is to transmit control signals through Radio Frequency and receive it through a receiver module in the car. We will have two switches in our remote control to power each motor of the car. The state of the switches (ON / OFF) is the control data. This data from the remote control is encoded before transmission, received back and decoded again to be sent to the motor drivers. This is achieved using an RF module and an encoder(HT12E)-decoder(HT12D) pair.
