Mobile Controlled Walking Robot

Today one of the common thing for all of us is Mobile or Smart Phone. Imagine there is robot which can be operated by your smart phone. Isn’t is cool?? Through this project you are going to build a unique walking robot which can be controlled by any smart phone.

You will need an Arduino to interface the microcontroller with the Servo motors and DTMF module. You will programme the microcontroller in such a way that as soon as you press the Specific number in the mobile app DTMF tone generator, immediately your walking robot will start walking into the specified direction. Let say you have programmed that whenever microcontroller receives a command for 2, the robot should walk in forward direction. Similarly 8 for backward, 4 for turning left, 6 for turning right. Now you had pressed the number 2, immediately tone for number 2 will be generated and the generated tone will be converted into digital signal by the DTMF module and it will be given to microcontroller as input. As soon as microcontroller receives the digital input, it will process the condition and once condition is satisfied, it make the robot to walk in forward Direction. Similarly this will apply for all the conditions.

Project Description:

1. DTMF Module: The DTMF module decodes the audio signal generated using DTMF technology into digital values which can be understandable by compiler
2. Arduino Uno: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
3. Servo Motors: A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is a signal (either analogue or digital) representing the position
4. Motor Driver: Generally the Arduino board is not capable of providing required amount of current for running the motors. So we use a device called Motor Driver which will provide sufficient current for driving the motors.

Project Implementation:

1. Interface the DTMF module and Servo motors with the Arduino board
2. Power the Robot and upload the code
3. Install the Android app DTMF Tone Generator from Play Store (available for free)
4. Connect your Smart phone to the walking robot through DTMF module
5. Test the Walking Robot by pressing different numbers in the app

Software requirements:

1. Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board

Programming language: Arduino Programming (C++)
