Paddleboat

In Da Vinci’s time, nautical expedition was

the most expedient method of communicating

with the world and his design for a boat

with large wheel-shaped paddles that

would propel it through water offered a faster

and easier method of water transportation.

Self-Propelled Cart

Da Vinci’s self-propelled cart was the first

to be capable of moving without being

pushed or pulled manually.

But it is not a car! It is a king of robot,

designed to take by self-movement a puppet on

the stage of a teather. And probably with

a programmed path.

Catapult

Improvements were made to the age-old military

launching device called a catapult.

The new design employed a hand-crank that

caused tension on the throw arm.

The spring design produced a large amount

of energy in order to propel stone projectiles or

incendiary materials over great distances.

Bombard

This improved cannon was designed to

include projectiles that contained a quantity

of mini gunpowder shots packed into petal-shaped

iron pieces that formed a ball.

The device exploded into fragments that had greater

range and impact than a single cannonball.
