Engineer-Amateur Dimitar Tilev constructed radio-controlled model vehicle which simulates the physics of motion of real, full-sized machines. The thing is the previously unknown – light models made of plastic and aluminum have quite different handling characteristics than the heavy structures of steel. In particular, they have virtually no inertia, and therefore can not show such spectacular stunts as drift or police turn.

Machine Tilewa made from a custom version of Oldsmobile Dynamic 88 Wagon 1963, designed for the solution of this engineering task. How to make a model whose weight is measured in grams, demonstrate the same physics of movement, that of the real car weighing more than a ton? To help the inventor come the servo motors and the Arduino chip.

The model has four separate servomotors, which are controlled via Arduino and can change the angle and rotation of each wheel. It works like an active suspension system, but the opposite – instead of conceal irregularities, the design mimics the movement with different load on each wheel. To monitor the movement here uses the accelerometer.

As a consequence, the model quite accurately copies the behavior of this heavy machine. “Squats” at the start, tilted when turning, comes into the drift, effectively inhibits. Dimitar Tilev no plans to sell its development, although it does not preclude the possibility of creating on its basis a kind of commercial version.
