The Desert Buggy works using a classic rubber‑band motor, which stores potential energy through tension. When wound and released, the rubber band unwinds and transfers energy through a series of interlocking gears. This gear train converts stored potential energy into controlled kinetic energy, turning the wheels and powering the buggy forward.

The open‑body structure allows users to observe mechanical principles in action including gear rotation, wheel axle movement, friction control provided by rubber tyres, and directional steering via the front wheel pivot system. This hands on interaction helps introduce foundational concepts of mechanical engineering, energy transfer, and motion dynamics in a simple, intuitive way.
