Tsar Tank

According to the memoirs of Lebedenko, the idea of this machine was prompted by Turkic carts, which, thanks to large diameter wheels, were able to easily traverse bumps and ditches.

The decisive audience for the project took place in January 1915 during which Lebedenko presented Nicholas II with a clockwork wooden model of his car with an engine based on a gramophone spring.

According to the recollections of the courtiers, the Tsar and the engineer played with a model of the machine which briskly ran along the carpet, easily overcoming stacks of two or three volumes of the "Code of Laws of the Russian Empire".

However, the rear steerable roller, due to its small size and the incorrect weight distribution of the machine as a whole, got stuck in soft ground almost immediately after the start of the test.

Design work on it was no longer carried out and the huge structure of the vehicle rusted for another 6 years in the forest some 60 kilometres (37 mi) from Moscow until 1923, when the tank was finally dismantled for scrap.
