Manufacturers like Tesla have long dreamed of autonomous vehicles. However, the idea of the robot car is not new. Leonardo da Vinci, who died 500 years ago, had already designed such a car. Whether he actually produced it is unknown.
Mechanical knight and mechanical lion
The artist engineer from Tuscany drew countless automatons and also "robots," for example a mechanical knight with cable rolls. There is evidence that he built and demonstrated his mechanical lion. The animal was able to walk a few steps. It opened its chest and distributed lilies.
Several institutions, including museums in Florence, Milan and Vinci, have tried to rebuild his constructions. There is also a model collection in New York.
Originally, his self-propelled cart was regarded as the forerunner of our car; today, it is assumed that it was intended for theatre stages. The spring-driven programmable vehicle was able to drive straight ahead, to the left and to the right. The images below present three replicas of different ages from Italy; they usually have three wheels.
