While most gear mechanisms are decades and even centuries old, the Eccentrically Cycloidal gear drive is so new the ink is still not dry on its patents. This video is published with the explicit permission of the patent holder.
This futuristically-looking mechanism is very efficient and extremely compact. The gear pair shown here has the gear ratio of 1:9, an almost impossible feat for a traditional involute gear pair.
