The mathematics behind the Experiment ZR012 are somewhat complicated, but the basic idea is easy enough to understand. In 1957, German engineer Felix Wankel created an engine that completed intake, compression, combustion, and exhaust through one rotational process. He had been working on the idea for decades and eventually succeeded by using nested epitrochoidal elements – making this shape is where the math gets complicated. It’s these shapes that the Experiment ZR012 utilizes for its movement and display. For a more detailed look at the engineering here, check out the official C3H5N309 webiste.
