Prepare to see what’s probably the most realistic remote control car ever, and we’re not just talking about the look. This car has a simulated suspension system under the hood, making the car rock and wobble in response to the motor revving as well as the braking, accelerating of the vehicle.
The creator behind the tiny vehicle is Dimitar Tilev, who revealed that many of the vehicle’s parts are 3D-printed like structural components, tires, wheels, along with the body of a 1963 Oldsmobile Dynamic 88 Wagon. The replica is about 3.4 kilograms heavy, so Tilev didn’t use miniature springs for bouncing movements as the car drives and stops. Because that wouldn’t look real, which is one of the most important things Tilev wanted for this build, taking him over one year to complete.
Instead of miniature springs, he chose servos that were as tiny, one in each corner of the vehicle, creating an active suspension system. Similar setups are used in over-the-top low-riders that are able to raise or lower their bodies high off the ground; however, the servos are used for a subtler effect.
In addition, this car packs an Arduino board monitoring real-time signals sent from an accelerator about the X and Y-axis movements of the vehicle. The data coming from the accelerator is for calculating how the suspension points each wheel would move in a certain situation if the car were in full size.
When the 1963 Oldsmobile accelerates, its front seems to raise while its back lowers, and vice versa when it stops along with some simulated jiggling making the car look even more realistic. It even lurches left and right each time the engine is revved corresponding to the torque from the engine. There are also LEDs in its tailpipes and fake engine noises.
