The car took a year to create â and a lot of trial and error. The system works with an accelerometer connected to an Arduino microcontroller board, which controls the four servos at each corner of the RC car. The servos can adjust the suspensionâs ride height. The board monitors X and Y-axis acceleration data and then calculates the positions for each of the four servos all in realtime.

The creator used a 3D printer for the hardbody, wheels, and tires, though a few cracks are already visible due to a few crashes. The details of the car werenât painted. Instead, itâs a wrap, though the creator admits in the blog explaining the build process, itâs not perfect. Itâs not an easy shape to wrap. Many of the suspension bits were 3D printed, too, but thereâve been no issues.
What really completes the build is the engine sound system that triggers a custom horn thanks to the Arduino microcontroller board, giving the Oldsmobile exhaust pops as it moves. At the back, tiny LEDs in the exhaust flash to signify flames, too.
It took a year to build the Oldsmobile with a functioning active suspension, and itâs an impressive RC car. Do they need lifelike suspensions? No, but just like real cars, even toy ones need a few modifications.
