witkali Obstacle Avoidance Robot kit using Ultrasonic Sensor ( Pre-assembled Project Kit ) with tutorials and code (3 wheels) Automotive Electronic Hobby Kit

Witkali Obstacle Avoidance Robot detects an obstacle in front of it and makes a new path. Here Ultrasonic sensor is used to detect the obstacle. The ultrasonic sensor emits and receives ultrasonic waves. The emitted wave will be reflected after hitting the obstacle. The time when waves are emitted and received will be used to calculate the distance between the robot and the obstacle. Which determines whether it should stop and make a new path.
