How to make money on a rover

Where to start your career as a famous person, or how to earn your first working money or “build” yourself a decent side income? Make someone paint a fence instead of yourself, like Tom Sawyer did? Sell ​​tickets to Failure so you don’t really fail, like Bender? So we already have it without him.

In any case, we must remember the main rule of commerce better than the Snow Queen adviser from the movie “The Snow Queen”, filmed back in Soviet times: “In summer, ice is rare and I sell ice. In winter, flowers are rare and I sell flowers! ”That is, you need to get rich on rarities, and today the“ most important rarity ”is Mars, where people are preparing to fly and where American spacecraft-rovers have landed.

Well, in any case, you can start your own business from an exhibition – one of the most effective means of public relations and advertising. And not paintings in the style of pop art or sculptural compositions from iron scrap, but … an exhibition of all-terrain vehicle models for the exploration of Mars. Landing apparatus “Kyuriosity” is at everyone’s hearing, which means we must take advantage of this. And today there were people who were able to make money on models of Martian all-terrain vehicles!

The exhibition “Space Program: Mars” with the help of various artistic techniques helps to present to the viewer what will surround him in the future during an interplanetary journey, and this is an excellent way to interest people in the problems of the space industry using modeling from improvised means.

The fact is that Tom Sesh and his assistants filled the exhibition space with structures from some rubbish and parts of unknown machines and mechanisms, plywood, polystyrene, various metal products, which, with their outlines, copy original NASA objects with amazing accuracy. The flight control panel, platforms for launching spacecraft, devices for splashdown, etc., were recreated.

The exhibition is located in a huge hall with an area of ​​55,000 square meters. feet where the rocky terrain of Mars is recreated. This is a good business, and at the same time, the installation of T. Sesha is a genuine anthem to science and intellect.

So this problem is solved for young people. But if T. Sesh and his friends created mock-ups of real devices, then it’s much more interesting to make the devices “fantastic”, which “could be”, and maybe “someday will be”! That is, to make models of Mars rovers for the study of Mars from improvised materials, but in such a way that they arouse interest in their appearance! Mars is, first of all, sand, and therefore the chassis of these all-terrain vehicles must be such that it provides them with high cross-country ability on sand! Let’s look around us and we will see many different items that are very easy to use for our purposes, for example – jars of Yantar cheese, mayonnaise, sour cream, or butter. Look at them carefully, and you will understand that in your hands you have a ready-made support element for the chassis of the most promising Martian all-terrain vehicle. How can it be? Yes, very easy! Cut an octahedron of such a size from the packing cardboard so that the width of each face is equal to the width of the bottom of this jar and stick these jars on them around the perimeter. What happened? Wheel with individual cameras having an extremely large footprint! Well, in order to increase the permeability of such a wheel even more, glue the second one to one such octahedron, while displacing the jars so that they connect to each other in a checkerboard pattern. Not enough eight faces? Make a wheel rim of 12, and then 24 cans for each such wheel, and 96 for all four wheels!

Now the case, which can be made from the same cardboard box packaging, antennas from disposable plastic plates! The model should be painted silver, somewhere to add a coating of chocolate foil, a “camera” on it, and you can expose it as a kind of designer refinement of your mind and imagination! It is also important that the rover will turn out to be quite large. Not a desktop model, and not a “toy”, but a completely “real device”, that is, a thing that makes you respect yourself! But on one model, even if the size of a desk, or even more, you will not go far. For the exhibition of Mars rovers, you need a “line of cars” – pieces 5, or even 10. Therefore, in addition to one rover, think of how to make several of them!

For example, in addition to one rover on four wheels, you can do exactly the same, but on six! Moreover, the middle pair should have a wheel axle capable of freely rising and lowering inside the vertical groove. What will it give? The increased cross-country ability, so for clarity, this Mars rover will need to be put on a small layout of the terrain, and not just a layout, but with such a relief that it shows how this middle wheel will roll over an obstacle!

A car on square wheels on Earth will not go far! But on Mars, a six-wheeled all-terrain vehicle on square wheels, and the average should be shifted relative to the other two by 45 degrees, and, accordingly, the “wheels” should also be shifted
