Meet NASA’s future Martian rover, the 12-TET-Rover:

The 12-Tet Rover is … 12 tetrahedrons made of 26 struts … that will roam all over Mars’ complex terrain. Unlike the current wheeled rovers, it will be autonomous, so it will not require instruction from a whole team of scientists to complete a simple task. It will recognize obstacles and figure out how to get around them. It has a huge advantage over wheeled rovers because it does not require flat ground to operate properly. Rather than use wheels, it extends its struts and tumbles forward.
