Recently, OpenAI announced they had gotten their dexterous manipulation system to solve a Rubik’s Cube . I thought I wouldn’t have much to say, until I started writing this. What Did OpenAI Do? Using reinforcement learning, they learned a controller for a Shadow Hand that lets them solve a Rubik’s Cube reasonably often. They report a success rate of 60% for average scrambles, and 20% for the hardest possible scrambles that require 26 quarter-face turns. I say doing RL on the Shadow Hand platform, but really, I mean they do learning on a simulated version of the Shadow Hand, then try to get tha
