IR CONTROLLED ROBOTIC VEHICLE
ABSTRACT
The
project is designed to control a robotic vehicle using a standard TV remote. IR
sensor is interfaced to the control unit on the robot for sensing the IR
signals transmitted by the remote. This data is conveyed to the control unit
which moves the robot as desired. An 8051 series microcontroller is used in
this project as control device.
Transmitting end uses a TV remote
through which IR commands are transmitted. At the receiver end, these commands
are used for controlling the robot in all directions such as forward, backward
and left or right etc. At the receiving end the movement is achieved by two motors
that are interfaced to the microcontroller. RC5 based coded
data sent from the TV remote is received by an IR receiver interfaced to the
microcontroller. The program on the microcontroller refers to the RC5 code to generate
respective output based on the input data to operate the motors through a motor
driver IC. The motors are
interfaced to the control unit through motor driver IC.
Further the project can be
enhanced by DTMF technology. With this technology we can control the robotic
vehicle by a cell phone. This technology has an advantage over long
communication range as compared to line of sight communication in IR technology.
