0.38 sec: Fastest Rubik's Cube-solving robot uses 6 Kollmorgen ServoDisc motors A pair of enterprising engineering students has posted a video online that shows a machine they built solving a Rubik's Cube puzzle in 0.38 sec -- the fastest in the world by far if they can get it made official (current world record is 0.637 sec). The machine was created by MIT Biometrics Lab Master's student Ben Katz and software developer Jared Di Carlo, and each has posted an in-depth blog about their creation and methods. "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. So we did," said Di Carlo, adding that each motor "can accelerate insanely fast. In a 10-ms quarter-turn move, the motor reaches over 1,000 rpm." Katz said the device uses six Kollmorgen ServoDisc U9-series motors. "Two were taken from my old robot arm project, the rest were found pretty cheaply on eBay," he said. Two PlayStation cameras are also part of the mix. Read Katz's blog, which contains videos and a link to his partner's page.

Top Product: Pistons made of sapphire? Mid Michigan Research selects Insaco for critical part fabrication If you want a prototype piston made of metal for research purposes, you have a lot of options -- you can even 3D print your own. But what if you need something much more exotic, like the second-hardest natural material? When Mid Michigan Research had just such a need, it turned to Insaco for the company's long history of custom fabrication of sapphire precision parts, often in unusual forms.
