22,00 €PRM booklet not included from Jule 2013 Sheets 90/v and 91/r of the Madrid Code include drawings of “strange” mechanisms that are not linked to the treatise on mechanics and often have no explanatory text. Analysing them led to the reconstruction of mechanisms enabling a mysterious animal, a mechanical lion, to move robotically. The lion, a gift from Pope Leone X and the town of Florence, was taken to Lyon, in France; on July 12 1515, at the end of a surprising, magical walk before the King of France, Francis I, it stopped knocking some lilies over. It can be considered one of the first animal-like robots ever built. Per saperne di più -

Among the several war machines designed by Leonardo, there are true pieces of artillery such as spingardes.The drawings on the 32r sheet of the Atlantic code hide ingenious insights for that age and represent two different versions of the spingardes. The first was mounted on a tripod and held with wooden pegs along a perforated ring; this solution allowed varying the height of the shot and was designed for spingardes of large dimensions.Our model is a reproduction of the second project: a spingardes with a rotated barrel that allowed the transport of a shed or mantlet, which was intended to protect the gunner.Originally designed for the launch of stones, spingardes were then used with the invention of gunpowder to launch bullets and darts of various types.In fact, some studies related to bullets and recipes of gunpowders are represented on Leonardo's sheet.

18,00 €The catapult was a medieval weapon which Leonardo reworked and improved upon. As shown in the drawings on page 140a/br of the Atlantic Code, which represent six designs of a spoonshaped catapult, the loading mechanism is activated by two large flexible wooden arms that increase launching power. The stone or metal projectile is placed in the spoon-shaped end of a long lever. The loading operation turns the large central pin and flexes the curved wooden arm. The safety catch is then released to launch the projectile straight at the target. The launching power is proportional to the length of the lever arm and so the energy involved in throwing the projectile is high, allowing the projectile to cover particularly long distances.

19,00 €Helicopter Leonardo da Vinci Italeri This machine, which is considered the ancestor of the modern helicopter,appears in a drawing dated roughly 1480 contained in theCodex Atlanticus. Leonardo outlines the plan for an “aerial screw”imagining it as a worm screw with a diameter of approximately 5metres, in his intentions, it should have “screwed itself” in air takingadvantage of its density. Moved by the muscle strength of four menwalking on the central platform, it consisted of a wooden structurecovered with starched linen cloth. Since there is no proof that Leonardoactually built the machine he imagined, it remains one of hismany theoretical insights. Per saperne di più -
22,00 €On page 945/r/ of the Codex Atlanticus, Leonardo da Vinci drew many devices for the plan of a mechanical paddle boat. One or more sailors can alternate working the pedals. The pedals transfer the alternate motion to a central gear, where it becomes linear motion, and a series of gears transfer it to the two big paddles on the sides of the craft. The central gear is drawn in more accurately on another page, 30/v/, and the mechanism works through springs hidden in the two main wheels that alternate. Per saperne di più -
18,00 €The ornithopter is a machine designed to fly by the flapping of its wings in imitation of birds.In 1485, Leonardo da Vinci began to study the flight of birds. He grasped that humans are too heavy, and not strong enough, to fly using wings simply attached to the arms. Therefore he sketched a device in which the aviator lies down on a plank and works two large, membranous wings using hand levers, foot pedals, and a system of pulleys. Per saperne di più -

22,00 €PRM booklet not included from september 2013 This model represents one of Leonardo da Vinci's most intriguing designs. It has been known as "Leonardo's Automobile" but recent studies consider it one of the first robots in history. The machine is drawn on folio 812/r/ of the Codex Atlanticus together with other devices. The robot's engine is hidden internally: a spring held fast by a stopping mechanism trasmits motion to the gears that move the wheels on the sides. Per saperne di più
