This functioning 1:35 scale model was developed, printed, and constructed over the course of a year and a half. It includes an automated transfer track, launch, brake run, and station that are all run by an Arduino Mega controlling 9 micro servo motors, 1 BLDC motor, and 6 hall sensors.
Stay tuned for a final video, but for now, take a look at what it took to bring this concept into reality via the link below:
