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.
