The video below shows an intense race between the Mindcuber robot and my 11 year old human daughter. This was a really fun and easy to build project that we found on mindcuber.com using the LEGO Mindstorms EV3 robotics set. The robot is fast, but not too fast so this is actually pretty competitive.
If you want to see a really fast cube solving robot, see the video below to watch the Cubestormer 3 robot smash the Guiness World Record for a single solve.
11/14/15 Update: Looks like the world record was just broken again. A new robot was able to solve the cube in just 2.39 seconds. See the video below.
