Voice controlled robotic vehicle

Abstract

This project was constructed in a way that allows the robot to be controlled by voice instructions. An android application with a microcontroller is used for critical tasks. The android app and the car can connect thanks to Bluetooth technology. The user can utilise the program's buttons or speak commands to the robot to control it. The microcontroller at the receiver side is coupled to two DC servo motors that allow the robot to move. The Bluetooth RF transmitter transforms the application's commands into digital signals for the robot at a reasonable range (about 100 meters). At the receiver end, the data is decoded and delivered to the microcontroller, which uses it to drive the necessary DC motors. The goal of a voice-controlled robotic vehicle is to carry out the necessary work by paying attention to the user' sorders. For the user to operate the robot smoothly, a prior preparation session is required. A code is employed for the same purpose to instruct the controller.
