That was fun.
It shouldn’t be surpising. The fact there are step by step instructions on how to solve Rubik’s cube means it is a programmable algorithm.
Then it is a matter of manipulation and some basic optical acuity.
I am not a robotics/AI guy (I checked into it and the math was cool but just not up my alley). But this is great to see and, as with so many basic things technological, a stepping stone to what we will no doubt soon call astonishing!
By cool do you mean interesting?
