Leonardo Da Vinci's Self-Propelled Cart

thingiverse

Leonardo Da Vinci's cart showcases his ingenious design skills in creating machines that continue to amaze us today. Like many of his innovative creations, this cart was never brought to life due to the limitations of its time. Instead, it was designed specifically for use in Renaissance Festivals as a special effects tool, not meant for actual transportation. The cart's power comes from two mainspring barrels located at the rear, which regulate acceleration through springs branching off the top of the cage. Steering is achieved by manipulating a lever attached to the front wheel axle, while programming can be done using modular blocks on the mainspring barrels - as seen here in their fixed state. This remarkable invention was meant to demonstrate how technological advancements during the Renaissance influenced innovation, and how creative problem-solving overcame the limitations of its time. Unfortunately, I remain uncertain about this model's functionality due to my inability to successfully print it.
