Obstacle Detection and Avoidance Robot

Abstract

This is a cost effective obstacle avoidance circuit developed in Amrita University. This robot is driven with an Arduino board controlled by an ultrasonic sensor. The obstacle is being detected at a distance of 15 cm when it senses the right path to move with the level of distance to the next obstacle. The number of vehicles is tremendously increasing day to day and the risk factor of accidents also increases with it. The Bluetooth module acts as an interface to communicate with the device using android apps. While driving the system with 76.93cm/s speed, an accuracy of obstacle detection of 92.5 percent is being achieved.
