armored machine
Leonardo's idea for an armored machine eventually became the idea for a modern tank. The armored machine was driven by men inside. They would turn cracks that turned the wheels of the machine. Inside the armored machine there were cannons that would fire at the enemy. Leonardo da Vinci put the gears in the wrong order on propose so no one will steal his idea. It was sketched around 1485. In September of 1915 a tank was created in Britain. The tank was called " Little Willie". It was used for the Royal Navy. The tank by Leonardo da Vinci was tested and was a half success. Since the gears were in reverse it was hard to build it. Therefore it was not as accurate as if Leonardo made it.
