NASA Rover

Last crawled date: 7 months ago

Cargo 100 tons + 10(?) tons cart
There is more gravity on Mars than on the Moon = 34.8 tons weight
Surface 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 N
Airless tires 2 m diameter, geared motor for each wheel
Rover turns by difference in wheel speeds on the right and left
Coefficient 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 hold
With a wheelbase of 12 m, suspension travel is 4.4 m / 44 s = 0.1 m/s
Transportation speed 12/44 = 0.27 m/s – travel time about 5 hours
Active suspension, terrain sensor ahead along the path of the rover (drawing)
Required power per rack 5.7 kW
Efficiency 0.8 – drive for 1 rack 7 kW
Mechanical transmission screw - nut (ball screw)
Diameter 100 mm, thread angle 2 degrees. pitch 10 – 11 mm
Rotation speed 10 r/s = 600 rpm
Containers with batteries on the sides of the cart
Solar panel for charging batteries when there is sufficient light
Rotate the panel 360 degrees and tilt towards the light up to 45 degrees
Overpass for loading at the beginning and unloading at the end of the route
Possibility 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 only
Everything is very simple. If you have any questions I will try to answer

*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 :)
