Exploration of Mars in the near future will becarried out with the help of automatic rovers. NASA is actively developing various models of alien transport, designed to solve the most difficult problems. The presence on Mars of numerous craters and funnels, in the depths of which there is an inexhaustible storehouse of data for earth science, requires the creation of original devices. One such research vehicle, the DuAxel transformer rover, was presented by NASA engineers.
The uniqueness of the DuAxel four-wheeled rover(abbreviated from "dual-Axel") consists in the possibility of dividing it into two two-wheeled, relatively autonomous devices, such as Axel, connected by a cable and a cable. Such a design will help in studying the steep slopes of Martian craters.
Consisting of two two-wheeled all-terrain vehicles,known as Axel, the rover, splits as it approaches the rim of the crater. One half remains in place, firmly fixing its position, being, in fact, an anchor for the other half, going down the slope. Both halves are connected by a cable that automatically unwinds when driving. The research is carried out using scientific equipment located in the wheel hub. Upon completion of the work, the "researcher" pulls up to the anchor, engages and DuAxel continues to move.
The first system tests were carried outlast fall during field tests in the Mojave Desert, when a group of engineers from NASA's Jet Propulsion Laboratory in Southern California conducted a series of tests on the modular rover.
The presented device will expand the possibilities alreadythe Mars-powered Curiosity device or the Perseverance rover flying towards the Red Planet, as both of these rovers can explore surfaces with a slope of no more than 30 degrees.
