In this instructables, I am going to show and explain the recipe of my voice controlled robot car. I used Amazon Alexa for voice command. I develop a custom skill for the robot. When you say, “Alexa, drive the car forward” or “turn right” Alexa trigger the AWS Lambda and Lambda function sends a command to an MQTT server. For making the car I used Arduino Uno and Raspberry Pi. Raspberry Pi receives the MQTT message from the server and sends it to Arduino using the USB port. Arduino controls the motor according to the received command. In the next few steps, I will show all the procedure step by step. So, keep reading. Before going the next step please enjoy the video.”
