Neat concept. I like the use of passive properties of its materials and construction to help it move over rough terrain. It reminds me of the Mars Ball, an experimental Mars rover project developed in the 1980s at the University of Arizona: https://www.lpl.arizona.edu/about/history/mars-ball-project https://www.lpl.arizona.edu/about/history/mars-ball-project The Mars Ball was basically a payload suspended between two huge wheels each of which had soft inflatable segments. Rather than using cameras or LIDAR and SLAM to navigate the rocky terrain of Mars, the Ball could simply roll right over any obstacles.
