I find it strange that people here are fixated with the solving software part. What's really cool to me in the project is the mechanical solution; fitting all the motors, axles, MCU, sensors and battery inside a customized cube.

Exactly this!

The solving algorithm is no big deal at this point. Experienced cubers can solve them in under 10 seconds. There are machines that can solve them in < 1s. [1] Again, the innovation there is the accuracy and precision of the machinery involved.

The fact they designed custom servos for this surprises me.

That's a significant time/cost, and typically out of reach for home electronics hobbyists.
