An ESP32 drives the motor, receiving its commands through WiFi, while the complete setup is controlled by a Raspberry Pi that runs the cart through a predetermined sequence. ![]() ![]() This means that technically this model isn’t a roller coaster, since the cart never makes a gravity-powered drop it’s actually a small rack railway, powered by a lithium-ion battery carried on board the cart. The main trick to the system’s unique motion is that the cart is motorized: a brushless DC motor moves it along the track using a rack-and-pinion system. The track and cart are all made of 3D printed pieces, which altogether took about 400 hours to print. fixed this deficiency by designing a model roller coaster that accurately simulates a full-sized ride. However, they actually make a poor analog of a full-sized ride, as gravitational force and aerodynamic drag don’t scale down in the same way, model roller coasters usually move way faster than the same design would in the real world. While they don’t give the physical thrill of a real one, model roller coasters are always fun to watch.
