This tweet by Woj Zaremba is bewildering. If we all agree it's about physics and manipulation, how do you get to claim that a failure in manipulation doesn't matter?

> It’s 20% success rate to solve the most difficult configuration of Rubik’s cube. However, on average the success rate is 60%. Moreover, the failure is by dropping the cube. The hand always solves the Rubik’s cube if you put it back the cube after the drop.
- randyrand 7y agoThe takeaway from that comment is that it's not like the robot is just unable to solve certain cubes or has an equipment failure, etc.
- scotty79 7y agoI think it just points out that hardest part is not dropping the cube. The hard problem they solved completely is orienting and manipulating the cube in an intended way, provided they managed not to drop it. Determining how to manipulate cube to get it solved state wasn't part of the problem as it is trivially easy for a machine or any human that learned how to solve rubiks cube.
