The problem Obstracle avoiding car Model Using Arduino Uno solves

The obstacle avoidance robotic vehicle uses ultrasonic sensors for its movements. A microcontroller of 8051 families is used to achieve the desired operation. The motors are connected through the motor driver IC to the microcontroller. The ultrasonic sensor is attached in front of the robot.
it also runs in remote places in hilly areas

Challenges we ran into
