Check out this crazy-cool invention called Inception Drive by Alexander Kernbaum of Stanford Research Institute (SRI), the same organization that developed Apple’s Siri. It’s an actuator, but one that uses a pulley-within-a-pulley to produce an infinitely-variable transmission. This technology could be used to make robots move more efficiently, and perhaps even make them safer. While Mr. Kernbaum’s focus is robotics, his invention could be applied to any number of uses where things move, and that’s just way cool. The IEEE Spectrum has more on the invention, including the video below. I love how Mr. Kernbaum is casually hanging out in a hallway with demo models of something that could change the way humanity’s machines move.
