You can consult the dedicated article Vehicles \u2013 Center of gravity \u2013 Center of inertia.<\/p>\n\n\n\n<p>The center of gravity is on the vehicle&rsquo;s center, the vehicle is considered symmetrical. To know its height, it is enough to determine the angle of the vehicle when it tilts.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"395\" src=\"https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2017\/12\/caisses_2.png\" alt=\"\" class=\"wp-image-673\" srcset=\"https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2017\/12\/caisses_2.png 800w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2017\/12\/caisses_2-300x148.png 300w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2017\/12\/caisses_2-768x379.png 768w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2017\/12\/caisses_2-600x296.png 600w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>To do this, we make an assembly. The vehicle rests on a plate (with a hole to let the braids and guide pass through. So the car rests on its 4 wheels. Fixed on an axis to make it rotate, the objective is to give an angle to the car and when it tilts, note the angle. How to know the angle in real time? No question of using a protractor, we need a more reliable solution. So I used a gyroscope as a sensor. The same element that is found on drones. It allows you to know all the angles of the sensor. Connected to a raspberry pi, we have the angle of the plate in real time on the screen.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"564\" src=\"https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_2.jpg\" alt=\"\" class=\"wp-image-2749\" srcset=\"https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_2.jpg 1000w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_2-300x169.jpg 300w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_2-768x433.jpg 768w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_2-600x338.jpg 600w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"564\" src=\"https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_1.jpg\" alt=\"\" class=\"wp-image-2748\" srcset=\"https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_1.jpg 1000w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_1-300x169.jpg 300w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_1-768x433.jpg 768w, https:\/\/www.carrera-fun.com\/wp-content\/uploads\/2020\/07\/angle_1-600x338.jpg 600w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p>On the side of the tires, a bar or stop prevents the vehicle from sliding but forces it to tip over.
