HOW TO MAKE WIRELESS ROBOT
Robotics can be defined as the science or study of the technology primarily associated with the design, fabrication, theory, and application of robots.I will explain the simple wireless robot using ASK (Amplitude Shift Keying) based Tx/Rx (transmitter/receiver) pair or RF MODULE operating at 434 MHZ.
This is a very simple project, and can easily be expanded to transmit temperature data, alarm status, remote control signals, and other information over wireless links.
The encoder IC takes in parallel data which is to be transmitted, packages it into serial format and then transmits it with the help of the RF transmitter module. At the receiver end the decoder IC receives the signal via the RF receiver module, decodes the serial data and reproduces the original data in the parallel format.
THE RECEIVER CIRCUIT DIAGRAM:
in order to control say a dc motor, we require 2 bits of information (switching it on/off) while we need 4 bits of information to control 2 motors. HT12E and HT12D are 4 channel encoder/decoder ICs directly compatible with the specified RF module.
In order to drive motors, we would need to connect a suitable motor driver at the output of the decoder IC. Bcoz the current is not sufficient to drive the motor. The motor driver circuit can consist of a relay, transistorized H-Bridge or motor driver ICs like the L293D, L298 etc.
