Ultrasonic Obstacle avoidance robotic Vehicle using 8051 Based Microcontroller

Obstacle avoiding robot which avoids the obstacles on its way .The project that we have made the robot keeps moving forward if the obstacle is more than 25cm the robot does not take any action and keeps on moving . If the distance is less than 25 cm the robot moves back and takes a left turn and keeps on doing this until the obstacle is avoided.And if the obstacle is just the way head that is less than 10cm the robot stop.
