Abstract
The project is about building a Multifunctional Robot with Obstacle Avoidance Robotic Vehicle using Ultrasonic sensors for its movement and Bluetooth control through manual or voice commands. A Microcontroller (ATmega328P) is used to achieve the desired operation. A Robot is a machine that can perform task automatically or with guidance. The project proposes robotic vehicle that has an intelligence built in it such that it directs itself whenever an obstacle comes in its path. This robotic vehicle is built, using a micro-controller of AT mega 328 family. An ultrasonic sensor is used to detect any obstacle ahead of it and sends a command to the micro-controller. Depending on the input signal received, the micro-controller redirects the robot to move in an alternate direction by actuating the motors which are interfaced to it through a motor driver. It has features as smart voice control by which user can give commands as left, right, front, back which gives another mode as manual operating mode.
