Meccano Build of Leonardo da Vinci's Self-Powered Cart
Summary: In October 2021, Alan Wenbourne created a Meccano model of Leonardo Da Vinci's self-powered cart, inspired by a large replica he saw at the Dover Transport Museum. The cart's motive power was provided by coil springs located in drums on the underside, with programmable steering using leaf springs and cams. Wenbourne's model used clock springs to replicate Da Vinci's intent, but further development is needed to optimize performance.
