Where was this when I needed it 30 years ago? Two students at Rowan University, Zachary Grady and Joe Ridgeway, have constructed a robotic arm that can solve the Rubik’s Cube in 15 seconds. As The New Scientist explains, the “system uses a camera to capture how the cube is scrambled and sends the images to a computer. It determines the pattern on each face and algorithms are used to solve the cube. The solution is then translated to the arm’s pneumatics and motors.” For more brilliant robot tricks, you can watch robots shoot archery, lead the Detroit Symphony orchestra, and even make ethical decisions
