Review on Advanced Obstacle Avoidance Techniques for Arduino-based Intelligent Vehicles

Abstract

Abstract: Robotics is a rapidly expanding and fascinating field in the modern world. Because of its high level of intelligence, a smart car can utilize all of the available space. This thesis presents the design and execution of a self-driving, obstacle-avoiding Smart Car that uses an ultrasonic wave sensor. The goal of the project is to create a Smart Car that can move around obstacles by employing ultrasonic sensors. To carry out the needed procedure, an ATmega328 microcontroller is employed. A machine that can work automatically or with instruction is referred to as a smart car. The proposal suggests a smart car that can selfsteer when an impediment is in its way since it has intelligence built into it. A microcontroller from the AT mega 328 series was used to construct this Smart Car vehicle. Any obstruction in front of it is detected by an ultrasonic sensor, which then sends an instruction to the microcontroller. The microcontroller instructs the Intelligent Car to travel in a different direction based on the signal that it receives by activating the motors that are connected to it by a motor driver. The roadblock avoidance distance may be calculated by emitting pulses. We can simultaneously manage the steering to carry out the function of obstacle avoidance. The Smart Car has rear wheel drive and front axle steering. Two electric motors using gear reduction systems power two driving tires. Using an Arduino MCU microchip as the brains of the Smart Car's control system. We construct our Smart Car platform while achieving positive experimental results through the design for both the software and the hardware systems.
