Cargo 100 tons + 10(?) tons cartThere is more gravity on Mars than on the Moon = 34.8 tons weightSurface slopes up to 20 degrees. path length up to 5 km*Strictly horizontal position of the load in two planes**An absolutely trivial task: Rover!6 supports then, for 1 rack 5800 kg = 56840 NAirless tires 2 m diameter, geared motor for each wheelRover turns by difference in wheel speeds on the right and leftCoefficient of friction tire – soil 0.4 – 0.6 (0.5!)Adaptation of a pair of wheels to the terrain +/- 10 deg (drawings)On a slope of 20 degrees, the all-terrain vehicle is guaranteed to holdWith a wheelbase of 12 m, suspension travel is 4.4 m / 44 s = 0.1 m/sTransportation speed 12/44 = 0.27 m/s – travel time about 5 hoursActive suspension, terrain sensor ahead along the path of the rover (drawing)Required power per rack 5.7 kWEfficiency 0.8 – drive for 1 rack 7 kWMechanical transmission screw - nut (ball screw)Diameter 100 mm, thread angle 2 degrees. pitch 10 – 11 mmRotation speed 10 r/s = 600 rpmContainers with batteries on the sides of the cartSolar panel for charging batteries when there is sufficient lightRotate the panel 360 degrees and tilt towards the light up to 45 degreesOverpass for loading at the beginning and unloading at the end of the routePossibility of transporting up to six 40-pound ship containers instead of a module (total mass 100 tons)The emblem of the Ukrainian Space Agency next to the emblem of NASA - can I dream?Quite realistic - Let's go!Model for illustration onlyEverything is very simple. If you have any questions I will try to answer________Ship 40ft standard container here:Shipping Container (40ft, High Cube)- Many thanks to the author.*Preliminary reconnaissance of the route, for example, on an ATV**If inside the module someone did not fasten their seat belts or left an unclosed bottle w...ith juice on the table :)
