Rubik's robot solves puzzle in 0.38 seconds [Video]

A robot that can solve a Rubik's cube puzzle in 0.38 seconds has been developed by two researchers in the US. The current world record is 0.637 seconds, which was set by German engineer Albert Beer and his robot Sub1 Reloaded. The researchers realised they could solve the cube more quickly by using a different type of motor in their robot. They suggested the contraption could be tweaked to go faster but said they had "lost interest" in tuning the device. Ben Katz, a student at the Massachusetts Institute of Technology, collaborated with Jared Di Carlo to create the robot. "We noticed that all of the fast Rubik's Cube solvers were using stepper motors and thought that we could do better if we used better motors," said Mr Di Carlo in a blog post. Mr Katz said in his blog the 0.38 seconds included "image capture and computation time, as well as actually moving the cube". Their contraption used two PlayStation Eye cameras from the old PS3 console to identify the configuration of the cube. However, mistakes often resulted in a cube being destroyed.
