Most Impressive/Advanced/Unique/Cool drivetrain you've ever seen

The particular design we developed was very easy to build. There are only three machined parts in each drive module (the modified gear, the structural support strut, and a small bracket that holds the load bearing in place). The drive modules can be used in either the cambered holonomic drive configuration (our version) or the traditional orthogonal holonomic drive configuration. In fact, we used the modules in the traditional configuration on our test robot for software development. So the answer is that it didn't take any longer to make this version vs. a traditional version. With regard to linear speed of the robot, it was designed for 10 ft/second. But it was never actually timed to determine real performance, so we can't attest to the actual speed.
