Leonardo da Vinci cam hammer is another example of his thinking centuries ahead of his time. This machine was used extensively for hundreds of years after his death during the Industrial Revolution.
The Steam engine powered them, and they could hammer up to twenty times per second. They were used to draw sheet metal for ships and armored machines for war, such as the tanks in World War I.
Below is his original drawing for the cam hammer –
Leonardo da Vinci’s cam hammer
As you can see, it was intended to be hand-cranked. This would rotate the cam upon which the hammer mechanisms rest and follow. When the cam is rotated, the hammer’s weight ensures that the bar connected to it always wants to be tightened up against it due to the force of gravity.
Eventually, the hammer and its mechanism follow the cam all the way around until it suddenly drops off – this also makes the hammer fall. Below is an animation showing the cam hammer in action –
Hammers like these continued to be used until the early 20th century when rolling mills replaced them. Rolling mills were much more powerful and efficient at rolling sheet metal to its desired dimensions.

Leonardo da Vinci’s sketches reveal his intention to reduce friction between moving parts. He conceptualized a bearing that utilized small metal balls to maintain smooth motion.
This mechanism required a ‘cage’ to keep the balls evenly spaced, which was key in providing stability and efficient motion. His work shows a deep understanding of friction dynamics and mechanical systems.
Da Vinci’s design aimed to optimize the power-to-weight ratio, which is crucial for inventions like his helicopter. Devices could function more smoothly and efficiently by lowering friction, marking a significant leap in mechanical design.

How did wheels work before ball bearings?
Before ball bearings, wheels relied on friction-reducing solutions like greased axles.
Older mechanisms often used materials like wood or bronze to minimize resistance.
The research on the possibility of Leonardo da Vinci perpetual motion machines was very thorough and scientific at the time. He has two pages of notes with several designs showing possible perpetual motion wheel.
Leonardo da Vinci wheels (the first, second, and third designs, from the left)
Among perpetual motion inventions, Leonardo’s first design is a simple overbalanced wheel. In this design, the weight of the ball bearings within the machine will always shift the wheel’s center of gravity away from the center point, thereby allowing continuous rotation. The design has 4 tracks in total, each with its own ball bearing running within it.
His second design incorporates levers and a pawl and racket system into the overbalanced wheel. The design of the wheel’s central hub is such that the levers are held in a controlled position throughout the rotation of the wheel. The pawl and ratchet system ensures that the wheel can only rotate counter-clockwise. This can be seen in the images above and will be shown in operation in the video at the bottom of the page.
His third and most elegant design is for another overbalanced wheel. This design has twelve tracks in total with a ball bearing in each. Once again the center of gravity is constantly shifted by the movement of the balls along the curved tracks during the rotation of the wheel. This design can be seen in the images above and will be shown in operation in the video at the end of the page.
We think his fourth design is a masterpiece of mechanical engineering and conceptual design. It is almost too difficult to explain how it works using words, instead, we will simply add some images of it and allow you to watch the video just below if you have not seen it already – the fourth machine can be seen at 3 minutes 22 seconds. You may have noticed that this model is missing from our set, to be honest, the simple reason why is that we could not manufacture this model without acquiring a 5 axis CNC machine – how someone could design this machine in their head is beyond comprehension, the man was a genius of the highest order.

Leonardo decided against investigating perpetual motion any further after he wrote (in mirror writing) beside the designs – “for every action, there is an opposite and equal reaction” (the machines will not work). That quote is also Isaac Newtons Third Law of Motion, 200 years before Newton was born!!!
Leonardo da Vinci Car Invention can be seen as a first in several categories
It is the first self propelled vehicle in history
It is the first invention of automobile in history
It is the first programmable machine in history
Leonardo da Vinci car
Although not strictly a car in our modern sense as it did not have seats for a passenger (although this is a simple modification) it is, by all means, a very well-designed machine. It is so well designed it is unlikely that it could have been built to Leonardo’s specifications for at least a couple of centuries as very detailed machine tooling would be required to build the complex gear systems inside the car.
Invention of the automobile was most likely designed for one of Leonardo’s wealthy patrons, he was regularly employed to create complex showpieces for his patron’s large and exquisite parties, such things would be a way for them to show their wealth to their guests.
Leonardo da Vinci’s car inventions were spring-driven so they had to be wound up before they would move, you can see the spring in the image below. It was also programmable – pegs were put into small holes to tell the wheels of the car to turn at certain points in time during the journey, it was all controlled internally by complex gearing and cog assemblies, self-propelled car designs and is a car a machine.
Based on the spring diameters and instructions on Leonardo’s design, it is estimated that the machine could move for up to forty meters before needing to recoil.

Recreation of Leonardo da Vinci Car
In 2004, a team from The Institute and Museum of the History of Science in Florence decided to try and recreate Leonardo da Vinci self propelled cart. They spent several months designing a 3rd model of Leonardo’s Car based on his designs, once they had that done they CNC Machined all the components from the 5 different types of wood Leonardo outlined in his plan.
Eventually, after a lot of hard work, they succeeded in creating a full-scale working model, and we might learn how to build a self propelled car, here is a video they took of the DaVinci auto in action –
Another fascinating thing about the car invention is that it is also the first known source showing a steering column, it also features a rack & pinion gear system, these are found in the steering assemblies of almost all automobiles made these days, including those with power steering.
Leonardo da Vinci self supporting bridge instructions also exhibit similar features to his self propelled vehicle ideas.
The Leonardo da Vinci Automotive model replicates exactly what he sketched in his original design. This is a snap together model so no gluing is required. Leonardo’s automobile is the first self-propelled machine in history.
