Cool stuff by Matthew!

I saw this on BBC it was by imperial college london student called Matthew and was 33 seconds

Weird that the 3x3 robot crushes a human but a human (presently) crushes a 4x4 robot.

dude what you're talking about? throw a human at that machine and throw that machine at the human and let's see who crushes who
that thing must have some 100kg

max park can solve faster than bro

Crush = beats by faster time
3x3 Robot = 0.2 seconds vs. Human 2.5 seconds
4x4 Robot 30-50 seconds vs. Human 17 seconds

Think he knows that lol

It is interesting hiw fast 3x3 bots are more than 4x4 bots are. I think this is becasue of the 4x4 bot hardware. Its way harder to build something that can turn inner layers than just outer layers.

I think that another thing limiting it is the algorithm used to find the solution. Just from looking at the turns per second and the length of the machine's solve, it looks like it did about 75-100 turns to solve the cube. The God's number for 4x4 has a lower bound of 35 and upper bound of 57, which really shows that a better solving approach could definitely have been taken to reduce solve time significantly.

Is there currently an optimal algorithm for 4x4 like there is Korf's algorithm for 3x3? No. But an equivalent of an optimal solving algorithm for 4x4 created in the future would drastically improve this solver.

4x4 also doesn't have fixed centers so you can't just attach the centers to the machine to do turns
