Rubik cube solving machine: a tribute to Ernő Rubik

Back in September 2016 I demonstrated my Meccano Rubik cube solver (also called Rubik's Shrine) to a gentleman who was a guest in one of my Airbnb accommodations. The difference between this vid and the original vid is, that the ratio of the drive to rotate the satellite of the gripper has been reduced from 1:5 to 1:2. With this modification we could optimize the speed. NEMA 14 stepper motors were used, they are of course less powerfull than the NEMA 17 motors.

Very beautiful in the way that it moves

We showed the Rubiks Shrine at Skegex 2016, but later that year we were able to speed up the machine. In 2022 I substituted the DRV 8825 drivers by tmc silent stepperdrivers. The stepper motors are now completely silent.

@@Meccanokinematics I do remember your previous video. It does seem a bit smoother and quieter. Very nice work :-)

@@Meccanokinematics Some of our greatest creations have the potential to be greater I suppose!

@Meccano Man The machine in this video is faster, but the tmc drivers were only a recent addition from 2022 and this latest configuration has not been filmed yet.
