We will do our best with our sensors and control software to keep our robotic VX on safe terrain... but mistakes are expected. We want to minimize the exposure. Last year the CMU robot "Sandstorm" ended up high-centered on a berm on a switchback and burned its tires trying to free itself. We expect to run over stuff and want to minimize risk to the vehicle. Anyone have advice on skid plates? Any other advice on how to protect the underside? Thanks!
