Probably, this scientist remained one of the most underestimated geniuses of Russian mathematical science.
Stop walking mechanism.
Perhaps the most spectacular invention of Pafnutiy Chebyshev is his plantigrade machine.
Although it cannot be argued that this is his most famous invention. The talented scientist was talented in everything. Even without taking into account its mechanisms, his works on the theory of probability and in the field of prime numbers deserve the closest attention.
After such a fundamental invention as the wheel, the inventors tried to make it so as to turn the rotary motion into a "foot" motion. And even now this topic is relevant, and, in general, no one managed to cope with it to the end. This is noticeable in American military equipment - for example, in mechanical mules designed to transport military supplies.
But at the Paris exhibition in 1878, an academician from St. Petersburg has already demonstrated his lambda mechanism. And if you connect them in pairs, it is quite similar to a walking horse.
Academician Chebyshev.
Yes, he could only move in a straight line and using a conventional manual drive, that is, it was not equipped with an engine. The man had to push him stupidly like a cart, but the sight turned out to be bewitching.

After all, the slats and sticks somehow turned into a horse. What was the basis of the work of the hinges.
If you talk about what this person was, then you can write about it endlessly. Chebyshev was born in 1821 into a military family - a veteran of the 1812 war. For the sake of their son's education, the family even moved closer to Moscow in order to give their son an excellent education, and they succeeded brilliantly.
The teachers were worthy, first of all Platon Pogorelsky - a famous mathematician of his time.
In general, Chebyshev believed that the theoretically developed mechanisms should have practical implementation. Although he created a stop-walk only in a wooden form. The main thing in the work is the transformation of rotational movement into walking.
In addition to interesting mechanisms - a rowing boat, a certain prototype of a mechanical adding machine, … and others - Chebyshev left behind a rich heritage in the field of cartography and ballistics - he calculated the conditions for the flight of artillery shells. So, it was he who proposed replacing the nuclei with a projectile in the form of a cylinder. Until now, the calculation of the flight of shells in the fleet is calculated according to its methods!
At the age of 29, he was already a professor at the St. Petersburg Academy.
Probably, now his works on the theory of such mechanisms are acquiring special relevance. Indeed, with the development of robotics - including bipedal mechanisms - overcoming obstacles now takes on a special meaning, although so far it is still quite an expensive pleasure. It is worth paying attention to the cost of Japanese technology, and what even to mention about ordinary prostheses for a common person.
Until now, the car of academician Chebyshev can be seen in the Polytechnic Museum in Moscow. She will now delight and make you think about the principle of her movement.
