info: This ebook includes building instructions and programming (using scratch blocks) of a robotic Grabber vehicle, using a single Lego SPIKE Prime kit. The model includes an ultrasonic sensor that finds the obstacle's distance and moves accordingly in order to grab it and a color sensor that identifies the color area that it must place the object. The grabber mechanism is based on blocks.
