How to Make a Voice Control, Direction Control, Remote Control, Android and Arduino Robot, (3 in One)


Introduction: How to Make a Voice Control, Direction Control, Remote Control, Android and Arduino Robot, (3 in One)

About: I make hobbyist stuffs and play with electronics follow me to know more

This is a simplified version of any other voice control robot, No complex coding easy to understand coding with easy algorithm.

The app is developed in such a way that it convert the voice command to text and transfer the text to the connected Bluetooth device.

The bluetooth connected on the Arduino board receives text from the Android app as characters and stored them as string to the assigned String.

There are words pre-programmed (forward, reverse, right , left and stop) to the arduino , whenever the received text matches with the pre-programmed words ,the arduino executes the command that assigned to the words.

Arduino can connect to Laptop to monitor serial communication and check the working process and the words received by the Bluetooth.

Required Components:
Arduino Uno

Bluetooth Module

L293D Motor Driver

2x Gear Motor

2x Wheel

1x Chasis

A breadboard Connecting wires

Step 1: Circuit Diagram and Arduino Program

Connect the components according to the circuit diagram

Program the arduino with the uploaded bluetooth program

IF you have any doubts regarding the assembly of the robot please do reply I will add a video about how to assemble the components and make the mechanical structure.

Step 2: Tutorial and Working Video

Step 3: Android Apps

Voice control app:

Direction control app:

Bluetooth Remote control app:

How can the circuit diagram be arranged using the AT90USB1287 micro controller for making the bot??

What is that blue material over the battery and what is it used for and where can I get it? And as for the wires connecting the battery to Arduino can I just use the jumper wires Arduino has?


Question 4 months ago

How to dump the program in arudino is there any program available sir

how to download these apps as these are apk files

First of all, I followed the circuit diagram and have built the Arduino robot. I also have the application up and running. I am able to connect the Bluetooth module to the phone and when I press the button and say forward the serial monitor indicates the word. However, the robot does not move. In addition, If I say another command an error code will pop up on the phone saying Error 516 Broken Pipe. Has anyone else come across this problem and have they been able to fix it? Also, does it matter which wires go to the sockets for its corresponding motor?

I got same error ..So what I do now.... Please reply me answer in my mail...

plz send the code of voice controlling robot to

plz send the code ...To

Plz send coding for voice recognition robot

hey can u give me the source code of the android app plz my email is



can you send me the exact link of downloading voice command app and secondly how to open an bluwtooth.ino file.

I need a video on assembling of chassis as well

Could you send me the Android codes for these Apps for App Inventor, please? Thanks much.

how to use motor controller L293D
instead of the Ic driver?
please circuit diagram! :(

I've done everything as you described but the robot isn't working.
I've even used a 12V battery to check but didn't work. So could you
please suggest me what to do? And is it necessary to use the same motors
as you used?
