If you have a four-wheel drive vehicle, you may think that it’s pretty good for getting around off-road. On the other hand, for really extreme terrain navigation, the six-wheeled rocker-bogie mechanism, modeled with PVC pipe in the video seen here, is up to the challenge.

Not only are all six wheels powered independently in this model by electric motors, but the front two wheels can rock back and forth, and the left and right wheel set can even rotate with respect to each other. This allows to maintain wheel contact, even when facing proportionally huge obstacles

The video involves a few interesting tricks, such as mounting the motors using hose clamps through slots in the PVC pipe frame, seen at 2:30. Perhaps the most interesting part of this project is that creator Navin Khambhala, aka “crazyNK,” actually shows how to build the tools used in the video via the “card” notes that pop up throughout.
