Cell Phone Controlled Robotic Vehicle
Introduction

• The project is designed to develop a robotic
  vehicle that is controlled by a cell phone. DTMF
  commands from a phone are sent to another cell
  phone which is mounted on the robot. These
  commands are fed to a microcontroller of 8051
  family to operate the vehicle movement through
  motor interface.

Cell Phone Controlled Robotic Vehicle
Functionality

• Send commands from one cell phone to be received
  by another cell phone.
• Mounted on the robot to receive the DTMF (Dual
  Tone Multi Frequency) mode commands.
• Which are then decoded by a DTMF decoder.
• The corresponding codes are then fed to a
  microcontroller.

Cell Phone Controlled Robotic Vehicle
Functionality

• Microcontroller are programmed to recognize those
  codes to operate 2nos DC motors through motor
  driver IC.
• It commands for any direction movement as per the
  sent commands from senders mobile.
• The motors are controlled using motor driver IC
  which is interfaced to the microcontroller.
• It uses microcontroller from 8051 family and a
  battery for power source.

Cell Phone Controlled Robotic Vehicle
Disadvantage

• Cell phone bill.
• 2. Mobile batteries drain out early so charging
  problem.
• 3. Cost of project if Cell phone cost included.
• 4. Not flexible with all cell phones as only a
  particular ,cell phone whose earpiece is attached
  can only be used.

Cell Phone Controlled Robotic Vehicle
Military and Law Enforcement

• Remote control vehicles are used in law
  enforcement and military engagements for some of
  the same reasons.
• It can be used in the borders for disposing
  hidden land mines.
• Remote Controlled Vehicle is used by police to
  detect bombs, or some chemicals, etc.
• Remote controlled vehicles are used by many
  police department bomb-squads to defuse or
  detonate explosives.

Search and Rescue Operations

• UAVs and Robotic Vehicles will likely play an
  increased role in search and rescue operations in
  natural calamities like earth quakes, floods,
  wild fire and hurricanes.
