Great for any skill level whether youre a pro, enthusiast, or a beginner, assembling your new robotic car kit will help you learn to create circuits, program sensors and actuators, learn about the Internet of Things (IoT) and get hands-on programming, coding, electronics and robotics experience. [Obstacle Avoidance] Under this mode the robot car will automatically detect obstacles ahead of it no matter which direction it is from with the ultrasonic sensors on the platform by sending waves and calculating the distance. Keep your car away from collision and enjoy the fun. [Line Tracking] The line tracking modules at the bottom of the car make sure it follows the runway you design with its infrared transmitter tube and an infrared receiver tube.
