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 https://www.facebook.com/arduinolabviewsolidworks https://twitter.com/learnrobotix

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

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?
