We've already seen researchers at the University of Chicago and Cornell use coffee grounds to develop an entirely different type of robotic hand, and it looks like some folks at McGill University in Montreal, Canada have also been taking a similar approach to quite literally reinvent the wheel. That's being done as part of the Lunar Exploration Light Rover (or LELR) project, which is aiming to build a lunar rover that's light and able to navigate difficult terrain (i.e. the surface of the moon) with ease. One of the key aspects of that, of course, are the wheels, and the McGill researchers' solution is some
