Assemble set series Leonardo da Vinci designed the first self-propelled cart capable of moving without being pushed or pulled manually. This precursor to the automobile was one of the many inventions that Da Vinci created dealing with locomotion and transportation. The cart was powered by coiled springs and also featured steering and brake mechanisms. When the brake was released, the cart would propel forward, and steering was programmable to go either straight or at pre-set angles.
