Critics say this massive dorm is a 'psychological experiment.'. The "bounce" comes from metal bending and springing back into its former shape. instead you should use replaceable teeth on wheels the way we use in heavy tunnel drills. Within a year, the soft metal alloy of the unmanned explorer's wheels was showing obvious signs of wear as treads came loose and holes started to appear. Ready to use as a Pawn. The follow-on Mars 2020 rover project is designing and testing a modified wheel with greater durability over harsh terrain and sand traverse performance equal to MSL (despite an increase in rover mass), while minimizing wheel mass growth (Reference (7), p. 12). A significant portion of this work is dedicated toward the determination of the proper soil simulant to use in the test rig. Even though it might seem like a metal tire would be harder to produce or more expensive than a traditional tire, it could save money for trucking companies, because there's no problem with under-inflating the tire. Curiosity is the size of a 4x4 and the surface of Mars turned out to be much rougher than expected. NASA. For future rovers that will explore the surface of Mars, NASA scientists have created a tire that contains no air, can handle the rugged Martian terrain, and may even have applications on Earth for trucks and off-road vehicles. NASA's Mars 2020 rover looks virtually the same as Curiosity but there are a number of differences. Wheeled robots take many forms: 2-, 3-, 4-, 6- or 8-wheels, with and without suspension. Made for Mars, the wheel made of nickel-titanium alloy can change shape as needed. NASA's current Mars rover, the famed Curiosity, was designed with six aluminum wheels, each milled from a solid block of metal. An Earth-bound Jeep is outfitted with a tire built from a "shape memory alloy," or a metal that springs back into its original shape after being deformed. A good example is a maneuver to fix the wheels that the engineers have come up with and tested, but have not had to use yet. The rocks that Spirit and Opportunity studied showed scientists that a long time ago, water on Mars may have looked a lot like water on Earth.
