Development of Smart Car system for Accident Prevention

In today’s world ROBOTICS is a fast growing and interesting field. SMART CAR has sufficient intelligence to cover the maximum area of provided space. Introduces the design and implementation of an autonomous obstacle -avoiding Smart Car using ultrasonic wave sensor in this thesis. The project is design to build an obstacle avoidance Smart Car vehicle using ultrasonic sensors for its movement. A microcontroller (ATmega328) is used to achieve the desired operation. A Smart Car is a machine that can perform task automatically or with guidance. The project proposes Smart Car vehicle that has an intelligence built in it such that it directs itself whenever an obstacle comes in its path. This Smart Car 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 Smart Car to move in an alternate direction by actuating the motors which are interfaced to it through a motor driver By sending pulses, the obstacle avoidance distance can be measured. At the same time, we can control steering gear to realize the obstacle avoidance function. The Smart Car uses front axle steering, rear wheel drive arrangement. Two drive tires are driven by two DC motors with gear reduction mechanisms. Using Arduino MCU chip as the control core of the Smart Car. Through the design of the hardware and software system, we build the Smart Car car platform and obtain good experimental effect.
