      I mean, hal, robots can totally solve rubiks cubes. This is not a big open problem Here's a robot built with legos! Legos, hal. And a cell phone! And it's infinitely more capable than the openai "demo."https://www.youtube.com/watch?v=X0pFZG7j5cE …

      Replying to @halhod @GaryMarcus and

      using a robot hand to rotate a cube and spin the top in a stable configuration is a nice research project, but barely a "challenge." also it didn't work 8 out of the 10 times they tried it on the actual robot.

      The hand costs 300,000 dollars. It is very special purpose, and, for this task, there are remarkably simpler and cheaper solutions. Why should one tie their hands behind their back to make a problem artificially harder?

      Thee sim2real canard is ridiculous. The only reason RL people claim sim2real is hard is because their simulators are garbage. It is standard robotics practice to develop in simulation and then deploy in real robots.

      Sim2real has two separate axis physics and perception. Physics is typically fine (airplanes etc. are complex and simulated with an amazing accuracy). Sim2real for perception is really hard but they have no perception, it is perfect state.

      Loading seems to be taking a while.
