VOICE-CONTROLLED ROBOT USING RASPBERRY PI AND BLUETOOTH

In this digital technology era for all the risky and dangerous tasks we prefer Robots rather than people. In the early stage of this Robotics the Robes are manually controlled but due advancement in wireless technology now Robes can be controlled via voice This project employs voice commands to control through an Android app linked to a microcontroller via Bluetooth .Users can control the robot either by tapping buttons on the app or by speaking commands. Movement is powered by two DC servo motors connected to the receiver microcontroller. The voice commands are converted in to digital signals by the Bluetooth RF transmitter for an appropriate range to the robot. At the receiver end the data gets decoded by the receiver and is fed to the microcontroller which drives the DC motors for the necessary work. This research objective is to design and implement a cost effective but yet flexible, adaptive and secured voice controlled robotic vehicle to perform the required task by listening to the commands of the user. Voice interfaces offer numerous advantages. Notably, they eliminate the need for technology training making them instantly accessible to users.
