Not much, I suspect, except for this amazing robot that can solve a Rubik’s cube in .38 seconds. The video, above, shows the cube in an unsolved position and then the actuators jump into action, slamming squares into place like some kind of crazed version of Will Smith’s character in *The Pursuit of Happyness*.   Created by [Ben Katz](http://build-its-inprogress.blogspot.com/2018/03/the-rubiks-contraption.html) and Jared Di Carlo, the project uses [set of 6 Kollmorgen ServoDisc U9-series motors and 2 Playstation Eye](http://build-its-inprogress.blogspot.com/2018/03/the-rubiks-contraption.html) cameras. The contraption reads the cube, solves it, and then slams the thing around in seconds. The team also used a unique AND board that ensured that each motor would turn on and off independently, a feature that is necessary to ensure the entire thing doesn’t explode if the motors were to actuate at the same time. It then uses the [min2phase](https://github.com/cs0x7f/min2phase) algorithm to solve the cube in about 21 moves. They could even make the thing slightly faster with a bit of tweaking.

As someone who is still so fascinated with this timeless toy that I often steal it from my kids, hats off to Katz and Di Carlo.  This bonus video features a cube exploding mid-solve:  [![original-stonewall_1-17_retargeting_banner_v4_dm3.png20170203-16093-s1075o](https://eng-pes.com/hs-fs/hubfs/Imported_Blog_Media/original-stonewall_1-17_retargeting_banner_v4_dm3_png20170203-16093-s1075o-Jun-26-2026-03-31-23-5505-AM.png?width=728&height=90&name=original-stonewall_1-17_retargeting_banner_v4_dm3_png20170203-16093-s1075o-Jun-26-2026-03-31-23-5505-AM.png)](http://www.stonewallco.com/) - [Tweet](https://twitter.com/share) [![Winning Bids: Using Technical Expertise and Relationship Skills to Build Success](https://eng-pes.com/hubfs/Imported_Blog_Media/winning.jpg) ](https://eng-pes.com/blog/winning-bids-using-technical-expertise-and-relationship-skills-to-build-success) 1 min read #### [Winning Bids: Using Technical Expertise and Relationship Skills to Build Success](https://eng-pes.com/blog/winning-bids-using-technical-expertise-and-relationship-skills-to-build-success) [Admin](https://eng-pes.com/blog/author/admin) : Jul 10, 2026 7:32:12 AM Achieving technical excellence in a company’s chosen field is a commendable goal, but technical excellence means nothing if it doesn’t translate...
