(not alot of pictures so not alot to work off of) DuAxel is an evolution of the Axel system, a versatile family of single-axle rovers designed to access high-risk terrain on planetary surfaces, such as steep slopes, boulder fields, and caves – areas that would be challenging or inaccessible for current rovers in use, such as Mars Curiosity.
POWER OF TWO
DuAxel uses two connected Axel rovers to travel long distances. Upon reaching a steep slope or cliff they split in two so that one tethered Axel can rappel down the steep hazard to reach otherwise inaccessible terrain while the other acts as an anchor at the top of the slope. Learn More here
