Info: This ebook includes building instructions and programming (using scratch blocks) of a robotic Helicopter, using a single Lego SPIKE Prime kit. The model includes an ultrasonic sensor that changes speed rotation according to ground distance and a color sensor that speeds up or down that rotation. Finally, the led matrix screen shows the navigation of the helicopter based on the gyro sensor values.
