Professor Danielle George demonstrates the world鈥檚 fastest Rubik鈥檚 cube solver and explains how it works using just a smartphone and lego. The smartphone takes photographs of the cube using it鈥檚 built in camera and the software works out the fastest way to solve the cube. The smartphone then sends instructions to the lego arms to tell them which parts of the cube to rotate. The Rubik鈥檚 cube solver is a prime example of how electronics in our everyday lives are capable of doing unexpected things.
