We made an ultrasonic dance with the robot.

With the two big front eyes – called ultrasonic distance detection sensor, the robot is able to detect obstacles in front of it, and therefore make decisions to stop/reverse and avoid crashing onto a wall.

But, one interesting thing is that, if you set it to reverse, and put your hand in front of the sensor while dancing, the robot will dance forward and backward with you. Isn’t that amazing? Please try it and see how you think about it. 😉
